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.

■ Derating Curve

S8VS-015@@

S8VS-03005/S8VS-03012

S8VS-03024

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

°C.

1 AC Input terminals (L), (N) Connect the input lines to these terminals. (See note 1.)
2 Protective Earth terminal (PE) Connect the ground line to this terminal. (See note 2.)
3 DC Output terminals (

4 Output indicator (DC ON: Green) Lights while a direct current (DC) output is ON.
5 Undervoltage indicator (DC LOW: Red) Lights when a drop is detected in the output voltage.
6 Output voltage adjuster (V.ADJ) Use to adjust the voltage.

■ 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.

■ Reference Values

Note: Refer to page 15 for definitions of MTBF and life expectancy.
