BEFORE USING THE POWER SUPPLY UNIT

Pay attention to all warnings and cautions before using the unit. Incorrect usage could lead to an electrical

shock, damage to the unit or a fire hazard.

WARNING and CAUTION

zDo not modify.

zDo not touch the internal components, they may have high voltage or high temperature. You may get

electrical shock or burned.

zWhen the unit is operating, keep your hands and face away from it as you may be injured by flying debris in

the event of a fault.

zThis power supply is designed for use within an end product. Stick the WARNING label for users on the

system equipment and notify in the system instruction manual.

zNever operate the unit under over current or short-circuit conditions for more than 30 seconds or outside its

specified Input Voltage Range. Insulation failure, burning, smoke or other damages may occur.

zConfirm connections to input/output terminals are correct as indicated in the instruction manual.

zThis power supply has a possibility for hazardous voltage to appear at output terminal depending on the type

of failure. The outputs of these products must be earthed in the end equipment to maintain SELV.

If the outputs are not earthed, they must be considered hazardous and must not be made user accessible.

Note: CE MARKING

CE marking, when applied to the LS series products, indicates compliance with the Low Voltage Directive

(2006/95/EC) in that it complies with EN60950-1.

3. Explanation of Functions and Precautions

3-1. Input Voltage Range

Input voltage range is single phase 88 ~ 264VAC (47 ~ 63Hz) or 125 ~ 373VDC for LS25 ~ LS100.

For LS150, selectable switch 115/230VAC will decide the input voltage range as mentioned in the table below.

Input voltage which is out of specification, may damage the unit. For cases where conformance to various

safety specs(UL,CSA,EN) are required, input voltage range will be 100~240VAC (50/60Hz ).

Note : LS series able to withstand Input Surge of 300VAC for 5 seconds.

LS150 – Selectable voltage range

Selected Range Applicable Input Voltage Range in VAC Applicable Input Voltage Range in VDC

115 88 ~ 132 NA

230 176 ~ 264 248 ~ 373

3-2. Output Voltage Range

V.ADJ trimmer is for output voltage adjustment within the range of specifications. Turning the trimmer clockwise will

increase the output voltage. Note over voltage protection ( OVP ) function may trigger if the output voltage is increased

excessively.

3-3. Inrush Current

Power Thermistor is built in to protect the circuit from high Inrush Current. Please select suitable input switch and fuse

rating in case of re-input the power at high temperature.

3-4. Over Voltage Protection (OVP)

The OVP function will shutdown the output except for LS25. The input need to be removed for a few minutes, and then

re-input for recovery of the output. OVP setting is fixed and cannot be adjusted externally.

Note : For LS25, OVP function will cause the output into ”hiccup” mode and damage the unit.

3-5. Over Current Protection (OCP)

OCP function operates when the output current exceeds OCP specifications. The output will automatically recover when

the overload condition is removed. Do not operate overload or dead short conditions for more than 30 seconds, which

could result in damage or insulation failure.

3-6. Output Ripple & Noise

Ripple & noise are measured at 20MHz by using a 300mm twisted pair of load wires terminated with a 0.1uF film ca-

pacitor & 47uF electrolytic capacitor. When load lines are longer, ripple becomes larger. The output ripple cannot be

measured accurately if the probe ground lead of oscilloscope is too long. At low temperature, large ripple & noise may

also be observed due to large ESR of the internal Electrolytic Capacitors especially at -25degC. Output voltage rise may

not be smooth during initial turn on at low temperature.

3-8. Parallel Operation

(A) Operation to increase the Output Current is not possible.

(B) Operation as a Backup Power Supply is possible as follows.

1. Set the power supply output voltage higher by the amount of forward voltage drop ( VF) of the diode.

2. Please adjust the output voltage of each power supply to be the same.

3. Please use within the specifications for output voltage and output current.

4. Isolation / Withstand Voltage

4-1. Isolation Test

Isolation resistance between output and FG (chassis) shall be more than 100MΩat 500VDC. For safety, voltage setting

of DC isolation tester must be done before the test. Ensure that the unit is fully discharged after the test.

4-2. Withstand Voltage

This series is designed to withstand 3.0kVAC between input and output, 1.5kVAC between input and FG (chassis) and

500VAC between output and FG (chassis) each for 1 minute. When testing withstand voltage, set current limit of with-

stand voltage test equipment at 20mA ( Output-FG (chassis) : 100mA ). The applied voltage must be gradually increased

from zero to testing value and then gradually decreased for shut down. When timer is used, the power supply may be

damaged by high impulse voltage at timer switch on and off. Connect input and output as follows :

(a) Input ~ FG (chassis) : solid line (c) Output ~ FG (chassis) : 500VAC, 1min (100mA)
