Switch Mode Power Supply S8VS 3

Specifications

■ Ratings/Characteristics

Note: 1. Refer to the Engineering Data section on page 17 for details.

2. If the V.ADJ adjuster is turned, the voltage will increase by more than +15% of the voltage adjustment range. When adjusting the output voltage, confirm the actual output voltage from

the Power Supply and be sure that the load is not damaged.

3. The overvoltage protection of the S8VS-015@@ uses a zener diode clamp. If the internal feedback circuit is destroyed by any chance, the load may be destroyed by the clamped output

voltage (approx. 140% to 190% of the rated output voltage).

4. To reset the protection, turn OFF the power supply for three minutes or longer and then turn the power supply back ON.

5. The typical values indicate the values for an input condition of 230 VAC. All items are measured at a frequency of 50 Hz.

6. The inrush current circuits do not differ for voltage specifications. Therefore, the typical values are the data values for 24-V models.

7. The circuit forms are different, so the start up time is shorter only when using a 15-W power rating.

Note: 1. Internal parts may occasionally deteriorate or be damaged.

Do not use the Power Supply in areas outside the derating curve (i.e., the area shown by shading A in the above graph).

2. If there is a derating problem, use forced air-cooling.

3. Provide a space of at least 20 mm when using standard

mounting and horizontal mounting. If 20 mm is not available, make sure that the space is at least 10 mm. In this case, reduce the corresponding derating curve by 5

°C.

4. When mounting Power Supplies facing horizontally in a vertical stack, provide a space of at least 75 mm in between the Power Supplies. If 75 mm is not available, reduce the corresponding derating curve by 1

°C for every 5-mm reduction in

space. A space of at least 25 mm, however, must be provided. In this case, reduce the corresponding derating curve by 10

■ Mounting

Note: 1. Improper mounting will interfere with heat dissipation and may

occasionally result in deterioration or damage of internal parts. Use the product within the derating curve for the mounting direction that is used. Do not use the Power Supply mounted in any way not shown above.

2. Use a mounting bracket (S82Y-VS30P, sold separately) when the Product is mounted facing horizontally.

3. Heat dissipation will be adversely affected. When the Product is mounted facing horizontally, always place the side with the label facing upward.

4. Use PFP-M End Plates on the top and bottom of the Power Supply when mounting facing horizontally on a DIN rail.

■ Overload Protection

The Power Supply is provided with an overload protection function that protects the power supply from possible damage by overcurrent. When the output current rises above 105% min. of the rated current, the protection function is triggered, decreasing the output voltage. When the output current falls within the rated range, the overload protection function is automatically cleared.

Note: 1. Internal parts may occasionally deteriorate or be damaged if a

short-circuited or overcurrent state continues during operation.

2. Internal parts may possibly deteriorate or be damaged if the Power Supply is used for applications with frequent inrush current or overloading at the load end. Do not use the Power Supply for such applications.

■ Overvoltage Protection

Consider the possibility of an overvoltage and design the system so that the load will not be subjected to an excessive voltage even if the feedback circuit in the Power Supply fails. When an excessive voltage that is approximately 130% of the rated voltage or more is output, the output voltage is shut OFF. Reset the Power Supply by turning it OFF for at least three minutes and then turning it back ON again.

Note: 1. Do not turn ON the power again until the cause of the overvolt-

age has been removed.

2. The overvoltage protection of the S8VS-015@@ uses a zener di-

ode clamp. The output voltage will be clamped at approx. 140% or higher of the rated output voltage (approx. 140% to 190%). If the internal feedback circuit is destroyed by any chance, the load may be destroyed by the clamped output voltage (approx. 140% to 190% of the rated output voltage). The power Supply will not restart if the output is turned OFF by the overvoltage protection operation. If this occurs, replace the Power Supply.

■ Inrush Current, Start Up Time, Output Hold Time

■ Undervoltage Alarm Indication

LED (DC LOW red) lights to warn of output voltage drop.

Detection voltage is set to approx. 80% (75 to 90%) of the rated output voltage.

Note: This function monitors the voltage at the power supply output termi-

nals. To check actual voltage, measure voltage on the load side.

■ Maintenance Forecast

(S8VS-@@@24A@)

Displays when the maintenance forecast has reached the set value.

■ Indication and Output

When the product is purchased, “ful” will be indicated. As electrolytic capacitors deteriorate, indication changes to “

hlf”. “ful” will be

indicated for the maintenance forecast display for approximately one month after the Power Supply is first turned ON. The accumulated value will then be displayed depending on the ambient conditions thereafter. (However, the “

hlf” indication may not appear, depending

on the usage environment and the set value for maintenance forecast.)

S8VS-06024A:

After the remaining time to maintenance is reduced to less than two years, indication automatically changes to a value, which decreases from “

1.5” to “1.0” to “0.5” to “0.0” (year) as the running hours

increase. If the remaining time becomes less than 0.5 year, an alarm (

a02) and “0.0” are indicated alternately.

S8VS-09024A@/S8VS-12024A@, S8VS-18024A@/S8VS-24024A@:

If the maintenance forecast setting L (which can be set arbitrarily from 0.0 to 5.0 years in 0.5-year steps) is set to a value larger than two years, the indication automatically changes to a value (L - 0.5) after the remaining time to maintenance is reduced to the set years, and an alarm (

a02) and the remaining time are indicated alternately.

If the setting is less than 2.0 years, the indication changes to a value (1.5) after the remaining time becomes less than two years, and after the remaining time becomes less than the set time, an alarm (

a02)

and the remaining time (L - 0.5) are indicated alternately.

If the alarm (

a02) and a numeric value are indicated alternately, a

transistor ((12) maintenance forecast output terminal (Yrs)) will turn OFF to indicate the need for maintenance. (The transistor turns OFF when the maintenance forecast time is reached, i.e., there will be no continuity between (12) maintenance forecast output terminal (Yrs) and (13) alarm output common terminal.)

Note: 1. The remaining time to maintenance is based on continuous

operation, not including the time when the power supply is turned OFF.

2. “

ful” will be indicated until approximately one month of

time is accumulated to estimate the speed of deterioration and the output will remain ON (continuity between (12) maintenance forecast output terminal (Yrs) and (13) alarm output common terminal).

3. For details on the display, refer to Relationship between In- dication Value and Outputs of Set Value under Maintenance Forecast Monitor Function.

Switch Mode Power Supply S8VS 15

■ Maintenance Forecast Monitor Function

The Power Supply is equipped with electrolytic capacitors.

The electrolyte inside the electrolytic capacitor penetrates the sealing rubber and evaporates as time passes since it is manufactured, which causes deterioration of characteristics such as decreasing the capacitance, etc.

Due to this deterioration of the characteristics of the electrolytic capacitor, the Power Supply decreases its performance as time passes.

The maintenance forecast monitor function shows an approximate period left for maintenance of the Power Supply due to deterioration of electrolytic capacitors. When the period left for maintenance that the power supply forecasts reaches the set value, an alarm is indicated and an output signal is triggered.

Use this function to know the approximate replacement timing of the Power Supply.

Note: The maintenance forecast monitor function indicates an ap-

proximate period left for maintenance, based on deterioration of the electrolytic capacitor. It does not predict failures caused by other reasons.

Relationship between Indicated Values and Output of Set Values

■ Principle of Operation

The deterioration speed of the electrolytic capacitor varies considerably according to the ambient temperature. (Generally the speed follows “Rule of Two for every 10°C”; for every 10°C increase in temperature the rate of degradation doubles according to Arrhenius’s equation.) The S8VS-@@@24A@ monitors the temperature inside the power supply, and calculates the amount of deterioration according to the running hours and inside temperature. Judging by this amount of deterioration, the power supply will give the alarm indication and output when the period left for maintenance reaches the set value.

Note: 1. Due to degradation of internal electronic parts, replace the

power supply approximately 15 years after purchase even if indication and output of maintenance forecast monitor are not issued.

2. The maintenance forecast is accelerated or decelerated according to operating conditions. Periodically check indication.

3. Acceleration or deceleration of the maintenance forecast may cause the output to repeatedly go ON/OFF. Only the S8VS-09024A@, S8VS-12024A@, S8VS18024A@, and S8VS-24024A@ are equipped with output.

4. The accuracy of the maintenance forecast function may be adversely affected by applications in which the AC input is frequently turned ON/OFF.

■ Reference Values

Note: The maintenance forecast is the service life (the power supply’s

internal temperature is monitored at all times) of the internal electrolytic capacitor in actual operating conditions, and varies according to the customer’s operating conditions. 15 years is taken as the maximum period of the maintenance forecast.

■ Undervoltage Alarm Function (Indication and Output)

(S8VS-@@@24@@ Only)

When output voltage drop is detected, an alarm (a01) and lowest output voltage value are indicated alternately. The preset value of detection voltage can be changed in the setting mode. (From 18.5 to 27.5 V (18.5 to 26.3 V for the S8VS-24024@@), in 0.1V steps. The value is fixed at 20.0 V for the S8VS-06024@.)

Further, an output ((11) undervoltage output terminal (DC LOW)) to an external device is given from the transistor to notify of the error (excluding S8VS-06024@). (Output voltage drop = OFF, i.e., no continuity between (11) undervoltage output terminal (DC LOW) and (13) alarm output common terminal.)

Example: Outputting an Alarm When the Voltage Output by the S8VS-09024@@ Drops to the Set Value (19.0 V) or Lower

Note: 1. Operation begins after about three seconds since the AC

power is supplied.

2. The alarm is not indicated in the setting mode.

3. Press the ((8) Mode Key) after the output voltage is re-

stored, to reset alarm indication.

4. The undervoltage alarm function monitors the output terminal voltage of the Power Supply. To check the voltage accurately, measure the voltage at the load end.

Note: 1. Operation begins after about three seconds since the AC

power is supplied.

2. The undervoltage alarm function may also operate when an interruption in AC input is not restored within 20 ms.

In the case that the output voltage drops below the set value (19.0 V) and an alarm is issued

Safety Precautions

■ Precautions for Safe Use

Mounting

Take adequate measures to ensure proper heat dissipation to increase the long-term reliability of the product. Be sure to allow convection in the atmosphere around devices when mounting. Do not use in locations where the ambient temperature exceeds the range of the derating curve.

When cutting out holes for mounting, make sure that cuttings do not enter the interior of the products.

(15-W and 30-W Models)

Improper mounting will interfere with heat dissipation and may occasionally result in deterioration or damage of internal parts. Use the product within the derating curve for the mounting direction that is used.

Use a mounting bracket when the product is mounted facing horizontally.

Heat dissipation will be adversely affected. When the product is mounted facing horizontally, always place the side with the label facing upward.

Always provide a space of 20 mm even when mounting horizontally or facing horizontally. If a space of 20 mm is not available, at least 10 mm must be provided. When mounting Power Supplies facing horizontally in a vertical stack, provide a space of at least 75 mm in between the Power Supplies. For details, refer to Derating Curve on page 8.

(60-W, 90-W, 120-W, 180-W and 240-W Models)

Improper mounting will interfere with heat dissipation and may occasionally result in deterioration or damage of internal par ts. Use the standard mounting method only.

Wiring

Connect the ground completely. A protective earthing terminal stipulated in safety standards is used. Electric shock or malfunction may occur if the ground is not connected completely.

Minor fire may possibly occur. Ensure that input and output terminals are wired correctly.

Do not apply more than 100 N force to the terminal block when tightening it.

Be sure to remove the sheet covering the product for machining before power-ON so that it does not interfere with heat dissipation.

Use the following material for the wires to be connected to the S8VS to prevent smoking or ignition caused by abnormal loads.

Recommended Wire Type

15-W and 30-W Models

60-W, 90-W, 120-W, 180-W and 240-W Models

Installation Environment

Do not use the Power Supply in locations subject to shocks or vibrations. In particular, install the Power Supply as far away as possible from contactors or other devices that are a vibration source.

Install the Power Supply well away from any sources of strong, high-frequency noise and surge.

Operating Life

The life of a Power Supply is determined by the life of the electrolytic capacitors used inside. Here, Arrhenius’s Law applies, i.e., the life will be cut in half for each rise of 10°C or the life will be doubled for each drop of 10°C. The life of the Power Supply can thus be increased by reducing its internal temperature.

Ambient Operating and Storage Environments

Store the Power Supply at a temperature of −25 to 65°C and a humidity of

−25% to 90%.

Do not use the Power Supply in areas outside the derating curve otherwise, internal parts may occasionally deteriorate or be damaged.

Use the Power Supply at a humidity of 25% to 85%.

Minor electric shock, fire, or Product failure may occasionally occur. Do not disassemble, modify, or repair the Product or touch the interior of the Product.

Minor burns may occasionally occur. Do not touch the Product while power is being supplied or immediately after power is turned OFF.

Fire may occasionally occur. Tighten terminal screws to the specified torque (15 and 30 W Models: 0.8 to 1.0 N·m

60, 90,120, 180, and 240 W Models: 1.08 N·m).

Minor injury due to electric shock may occasionally occur. Do not touch the terminals while power is being supplied. Always close the terminal cover after wiring.

Minor electric shock, fire, or Product failure may occasionally occur. Do not allow any pieces of metal or conductors or any clippings or cuttings resulting from installation work to enter the Product.

!CAUTION

*1. Convection of air *2. 20 mm min.

If 20 mm is not available, however, at least 10 mm must be provided.

Do not use the Power Supply in locations subject to direct sunlight.

Do not use locations where liquids, foreign matter, or corrosive gases may enter the interior of products.

S8VS-@@@24A@ Models only

Satisfy the following conditions when storing the Power Supply for long periods of time to maintain its remaining service life function.

• When storing for more than three months, store within an ambient temperature range of

−25 to +30°C and the humidity range of 25%

to 70%.

Periodic Check (S8VS-09024@@, S8VS- 12024@@, S8VS-18024@@ and S8VS- 24024@@ only)

It may take from several years to more than 10 years under general operating conditions for the power supply to output the maintenance forecast monitor alarm (S8VS-@@@24A@). The total run time monitor (S8VS-@@@24B@) may be a similar number of years as the maintenance forecast monitor according to some settings. During operation over an extended period of time, periodically check if the maintenance forecast monitor output ((12)Yrs) or total run time monitor output ((12)kh) is correctly functioning by the following procedure.

1. Select the operation mode.

2. Check that the output ((12)Yrs/kh) is turned ON (with continuity

between (12) and (13)).

3. In the operation mode, press and hold the Down Key D (10) and

the Mode Key M (8) simultaneously

for at least three seconds.

The main display (6) changes to “

a02.”

An inactive output ((12)Yrs/kh) (no continuity between (12) and (13)) in the “

a02” indication indicates the correct function.

4. Release keys to return to the regular state.

Note: DC output stays ON during the periodical check.

Overcurrent Protection

Internal parts may possibly deteriorate or be damaged if a short-circuited or overcurrent state continues during operation.

Internal parts may possibly deteriorate or be damaged if the Power Supply is used for applications with frequent inrush current or overloading at the load end. Do not use the Power Supply for such applications.

Alarm Output (S8VS-09024@@, S8VS-12024@@, S8VS-18024@@, S8VS-24024@@ Only)

When using the alarm output, sufficiently consider the maximum ratings, residual voltage, and leakage current.

Transistor output: Sinking for S8VS-@@@24@ Models

Sourcing for S8VS-@@@24@P Models

30 VDC max., 50 mA max.

ON residually voltage: 2 V max. OFF leakage current: 0.1 mA max.

Charging the Battery

If a battery is to be connected as the load, mount an overcurrent limiting circuit and an overvoltage protection circuit.

Dielectric Strength Test

If a high voltage is applied between an input and the case (FG), it will pass though the LC of the built-in noise filter and energy will be stored. If the high voltages used for dielectric strength testing are turned ON and OFF with a switch, timer, or similar device, impulse voltage will be generated when the voltage is turned OFF and internal parts may possibly be damaged. To prevent the generation of impulse voltages, reduce the applied voltage slowly with a variable resistor on the test device or turn the voltage ON and OFF at the zero-cross point.

Inrush Current

When two or more Power Supplies are connected to the same input, the total current is the sum of the currents for each Supply. Select fuses and circuit breakers giving sufficient consideration to the fusing or operating characteristics so that fuses will not burn and breakers will not break due to inrush current.

Output Voltage Adjuster (V.ADJ)

The output voltage adjuster (V.ADJ) may possibly be damaged if it is turned with unnecessary force. Do not turn the adjuster with excessive force.

After completing output voltage adjustment, be sure that the output capacity or output current does not exceed the rated output capacity or rated output current.

15-W, 30-W Models

If the output voltage is set to a value less than −10%, the undervoltage alarm function may operate.

60-W, 90-W, 120-W, 180-W, and 240-W Models

If the output voltage is set to a value less than 20 V (the factory setting), the undervoltage alarm function may operate.

DIN Rail Mounting

To mount the Block on a DIN rail, hook portion (A) of the Block onto the rail and press the Block in direction (B).

To dismount the Block, pull down portion (C) with a flat-blade screwdriver and pull out the Block.

Series Operation

(24-V Model)

Two power supplies can be connected in series.

The (±) voltage output can be accomplished with two power supplies.

Note: 1. The diode is connected as shown in the figure. If the load is

short-circuited, a reverse voltage will be generated inside the Power Supply. If this occurs the Power Supply may possibly deteriorate or be damaged. Always connect a diode as shown in the figure. Select a diode having the following ratings.

2. Although products having different specifications can be

connected in series, the current flowing through the load must not exceed the smaller rated output current.

3. Serial operation is not possible with 5-V and 12-V Models.

Parallel Operation

The product is not designed for parallel operation.

In Case There Is No Output Voltage

The possible cause for no output voltage may be that the overcurrent or overvoltage protection has operated. The internal protection may operate if a large amount of surge voltage such as a lightening surge occurs while turning ON the power supply.

In case there is no output voltage, please check the following points before contacting us:

• Checking overload protected status: Check whether the load is in overload status or is short-circuited. Remove wires to load when checking.

• Checking overvoltage or internal protection (except for 15-W Models): Turn the power supply OFF once, and leave it OFF for at least 3 minutes. Then turn it ON again to see if this clears the condition.

Harmonic Current Suppression Circuits

(120-W, 180-W and 240-W Models)

A harmonic current suppression circuit is built into the Power Supply. This circuit can create noise when the input is turned ON, but it will last only until the internal circuits stabilize and does not indicate any problem in the product.
