Specifications

■Ratings/Characteristics

Note: 1. Do not use the Inverter o utput for the Power Supply. Inverters with an output frequency of 50/60 Hz are available, but the rise in the internal temperature of the Power

Supply may result in ignition or burning.

2. Refer to the Engineering Data (15-W, 30-W, 50-W, 100-W, 150-W Models) section on page 9 to 11 for details.

3. If the V. ADJ adjuster is turned, the voltage will increase by more than +20% 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.

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

5. Conducted emissions: The noise value is affected by factors such as the wiring method. The Power Supply conforms to Class B when the aluminum plate is laid under

the Power Supply. For 15-W models, insert a clamp filter (ZCAT2436-1330 by TDK: 50 Ω min. [50 to 500 MHz], or the equivalent) in the output wire to reduce noise.

6. Radiated emissions: The noise value is affected by factors such as the wiring method. The Power Supply conforms to Class B when the aluminum plate is laid under the
Power Supply. For 150-W models, insert a clamp filter (ZCAT2017-0930 by TDK: 35 Ω min. [50 to 500 MHz], or the equivalent) in the input wire to reduce noise.

Engineering Data (15-W, 30-W, 50-W, 100-W, 150-W Models)

■Derating Curve

300W/600W/1,500W

Note: Refer to page 15.
Note: 1. Internal part s may occasionally be dete riorated or d amaged. Do no t use the Power Supply in areas outside the d erating cur ves (i.e., the area shown by

shading A in the above graphs).

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

3. When mounting two or more Power Supplies side- by-side, allow at least 20 mm spacin g betw een th em. Mu ltiple 100- and 15 0-W models cannot be use d

side by side. Be sure to install the Power Supplies as far away from heat-generating sources as possible. As a reference value, allow at least 50 mm spacing
on the right and left sides. If only 20 mm spacing is allowed, use the Power Supply at a load ratio of 80% or less.

4. When using 150-W models for a long period of time at an input voltage of 90 VAC or lower, reduce the load to 80% or less of the above derating curves.

■Mounting

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

may occasionally result in deterioration or damage of inter­nal parts.
Use the Power Supply within the derating curve for the
mounting direction that is used.

2. Use the metal plate as the mounting panel (*1).

3. Install the Power Supply so that the air flow circulates

around the Power Supply, as the Power Supply is designed
to radiate heat by means of natural air flow.

4. Mounting screw tightening torque
(recommended value: M3 (0.49 N·m))

■Remote Sensing Function

(S8VM-100@@@@/150@@@@ only)

This function compensates a voltage drop on the load lines.
To use this function, connect after removing the two short bars of the
remote sensing terminal.

Note: 1. Use a 2-conductor shielded cable as a connection wire (*1).

2. Use as thick a wire as possible since high voltage drops on

the load lines (*2) may activate the overvoltage protection
function.

3. Use when the voltage drop is 0.3 V or lower.

4. When the +S and

−S terminals are opened with the shor t

bar removed, the overvoltage protection function is activat­ed and the output voltage will be cut off.

5. If the load line is too long, use an electrolytic capacitor in the
following 3 locations:

1) Across the load terminals

2) Between the +S terminal and + terminal

3) Between the

−S terminal and − terminal

Select the capacity of the connected capacitor from be­tween several tens to several hundreds of

µF as a guide,

and then determine the capacity when actually connecting
the capacitor between terminals as shown below.

Item Value Definition

Reliability
(MTBF)

135,000 hrs
min.

MTBF stands for Mean Time Between Failures, which
is calculated according to the probability of accidental
device failures, and indicates the reliability of a device.
Therefore, it does not necessarily represent the life of
the Power Supply.

Life
expectancy

10 yrs. min. The life expectancy indicates average operating hours

under the ambient temperature of 40

°C and a load rate

of 50%.
Normally this is determined by the life expectancy of
the built-in aluminum electrolytic capacitor.

Switch Mode Power Supply S8VM 11

■Overload Protection

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

The values shown in the above diagrams are for reference only.
Note: 1. Internal parts may occasionally deteriorate or be damaged

if a short-circuited or other overcurrent state continues dur­ing operation.
Eliminate the overcurrent state as soon as possible.

2. Internal parts may possibly be deteriorated or damaged if the
Power Supply is used for applications with frequent inrush cur­rent or overloading at the load end. Do not use the P ower 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 140% of the rated voltage or more is
output, the output voltage is shut OFF, preventing damage to the l oad
due to overvoltage. Reset the input power by turning it OFF for at
least three minutes and then turning it back ON again.

The values shown in the above diagram are for reference only.
*1 S8VM-@@@24A@/P@
*2 Except for S8VM-@@@24A@/P@
Note: 1. Do not turn ON the input power again until the cause of the

overvoltage has been removed.

2. The overvoltage protection function may be activated when
the output voltage adjuster (V.ADJ) is set to a value that ex­ceeds +20% of the rated output voltage.

■Undervoltage Alarm Function (Indication and Output)

(Only S8VM-@@@24A@/P@)

If an output voltage drop is detected with an S8VM-@@@24A@/P@ with undervoltage alarm function, the DC LOW indicator will light to notify of an
output error. The transistor also sends an output externally to notify of the error (except for the S8VM-01524A@ and S8VM-03024A@).

Transistor Output: Sinking type: (NPN) (S8VM-@@@24A@)

Sourcing type: (PNP) (S8V M-@@@24P@)
30 VDC max., 50 mA max., Residual voltage when ON: 2 V or less, Leakage current when OFF: 0.1 mA or less

• Undervoltage Alarm Function 1 (DC LOW1)
Only a momentary voltage drop is detected. Detection voltage is automatically adjusted internally by detecting the output voltage (approx. 2.7 V

lower than the voltage output at an output voltage of 24.0 V).
During detection, the transistor is OFF (with no continuity across 8 and 10) and the LED (6: Yellow) lights. (The Undervoltage Alarm Function 1 is
used as a latch holding function.)

• Undervoltage Alarm Function 2 (DC LOW2)
Detection voltage is set to approx. 20.0 V (from 18.0 to 21.6 V).

During detection, the transistor is OFF (with no continuity across 9 and 10) and the LED (7: Red) lights.
Note: 1. This function monitors the voltage at the Power Supply output terminals.

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

2. Gradual voltage drop is not detected by the Undervoltage Alarm Function 1 (DC LOW1).

3. Once undervoltage is detected by Undervoltage Alarm Function 1 (DC LOW1), the transistor turns OFF and status of the LED (6: Y ellow)

light is maintained. To reset the function, turn OFF the input power for 60 seconds or longer, and then turn it ON again.

4. If the output voltage remains at 15 V or lower for several seconds when using Undervoltage Alarm Function 1 (DC LOW 1), the output
hold status for detection may be reset.
