4. Functions and Precautions

4-1. Input Voltage Range

Input voltage range is single phase 85 ~ 265VAC (47 ~ 63Hz) or 120 ~ 330VDC. Input voltage, which is out of

specification, may cause unit damage. Rated input voltage for safety standard application is 100AC-240VAC(50/60Hz).

4-2. Output Voltage Range

Output voltage is set to the rated value at shipment. V.ADJ trimmer on the front panel side is may be used to adjust the

output voltage within the range specified.

Output voltage range is within ±20% of rated output voltage (48V Output Model : -20% ~ +10%).

To turn the trimmer clockwise, the output voltage will be increased. Take note when the output voltage is increased

excessively, over voltage protection (OVP) function may trigger and output voltage will be shut down.

4-3. Over Voltage Protection (OVP)

The OVP function (Inverter shutdown method, manual reset type) is provided. OVP function operates within 125-145%

of the rated output voltage value (48V type: 115-135%), and the output will be shut down when OVP function triggers.

To reset OVP, remove the input of power supply for a few minutes, and then re-input. Or, use CNT reset ( remote

ON/OFF : OFF to ON). OVP value is fixed and not to be adjusted externally.

Never apply more than rated output voltage to output terminal, which may leads damage. In the case of inductive load,

use decoupling diode at output line.

4-4. Over Current Protection (OCP)

The OCP function is provided. OCP characteristic is constant current limiting, (less than 5V output model: with Hiccup

operation) automatic recovery. OCP function operates when the output current exceeds 105%(24V output model: 119%)

of maximum DC output current specification. The output will be automatically recovered when the overload condition is

canceled. Never operate the unit under over current or shorted conditions for more than 30 seconds, which may leads

damage. OCP setting is fixed and not to be adjusted externally.

4-5. Over Temperature Protection (OTP)

The OTP function (manual reset type) is provided. When ambient or internal temperature rises abnormally, OTP

function operates and output will be shut down. After shut down, remove the input and cool it down to reset OTP.

Then re-input.

4-6. Low Output Detection Circuit (PF)

Low output voltage detection circuit is provided. Power Fail (PF) signal will turn “High” level to indicate the abnormal

status when the output voltage becomes within 65 ~ 80% of rated value caused by either the drop or brownout of the

input voltage or OCP, OVP and OTP function operation. When the built-in FAN motor of this power supply unit stops,

PF signal will turn to “H”. The PF signal is isolated from input and output by a photo-coupler. It uses the open collector

method shown in below.

4-7. Remote Sensing (+S, -S terminal)

This function compensates voltage drop of wiring from output terminals to load terminals. Connect “+S” terminal to “+”

terminal of load and “-S” terminal to “-” terminal of load with sensing wires. The total line voltage drop (+ side line and

- side line) shall be less than 0.3V. In case that sensing lines are too long, it is necessary to put an electrolytic capacitor in

following 3 placed;

1) across the load terminal,

2) between “+S” terminal and “+” terminal,

3) between “‐S” terminal and “‐”terminal.

When the function of remote sensing is not in used, connect +S terminal to +Vm terminal, and –S terminal to –Vm

terminal by the attachment connector.

If remote sensing terminals are opened, the stability and the accuracy of the output deteriorated. Therefore, terminal

+S, -S must be connected.

4-8. Remote ON/OFF Control

Remote ON/OFF control is provided.

Using this function, output on/off is allowed to control without input voltage on/off. The output is turned to ON when

TOG and CNT terminals are shorted, and the output is turned to OFF when these terminals are opened. When the

function is not used, connect TOG and CNT terminals. The standards for this function are as follows. “TOG” terminal is

return for “CNT” terminal.

(1) TTL compatible. The maximum input voltage to CNT terminal is 12V, and the maximum allowable reverse voltage

is -1V. The sink current for CNT terminal is 3.5mA.

(2) A switch and relay or a transistor can be used as ON/OFF switch.

(3) Remote ON/OFF control circuit is isolated from the input and output by a photo-coupler and can be controlled

regardless of the output potential (+ or -). Connect TOG terminal to ground of control signal.

c). Inserting contact into housing

Inserting crimped contact into housing

(1) Do not apply any pulling force to crimped part, and insert contact parallel to housing

(2) Insert contact into housing without stopping to innermost

(3) Check secure locking per each insertion by pulling wire softly in order to check that contact does not come off

housing. Besides, check whether there is the backlash in the direction of insertion axis.

d). Mating and Unmating Connector

(1) Inserting connector

Hold receptacle housing securely and insert into header straight against to header post until click sounds.

(2) Unmating connector

Hold all wires securely and fix receptacle housing by fingers so as to pry, and then, withdraw it on the mating axis.

e). Routing of Wire

Routing wire so as not to apply external force to connector except force to such an extent that wire slightly buckles,

considering an enough length to route and fixing of wire.

7. The life expectancy

The life of the power supply depends on the life of the built-in aluminum electrolytic capacitor being used and fan

mounted products will depend on fan life. Each life is described in reliability data.

The life of the aluminum electrolytic capacitor varies depending on the method of mounting the power supply, the load current,

and the ambient temperature. Please refer to “Electrolytic Capacitor Lifetime”.

The life of the fan depends on the fan intake or exhaust temperature. Please refer to “Fan Life Expectancy.

Please do not use the product which passed over the life expectancy. There is a risk of unexpected output shutdown and

specifications may not be satisfied.

Please contact us for maintenance or exchange the product which passed over the life expectancy.

8. External Fuse Rating

Refer to the following fuse rating when selecting the external fuses that are to be used on input line. Surge current flows

when line turns on. Use slow-blow or time-lag type fuse, not fast-blow fuse. Fuse rating is specified by in-rush current

value at line turn-on. Do not select the fuse according to input current (RMS.) values under the actual load condition.

9. Fan life expectancy

The Fan-life has limitation. Therefore, periodic maintenance by exchanging the life-expired fan is required for the

power supply. The following figure shows the life of fan.

The difference between the intake temperature and the exhaust temperature of the Power supply at Io=100% :

HWS300 : 4℃

HWS600 : 8℃

10. Before concluding that the unit is at fault…

Before concluding that the unit is at fault, make the following checks.

(1) Check if the rated input voltage is connected.

(2) Check if the wiring of input and output is correct.

(3) Check if the I/O terminal connection is properly tighten by regulated torque.

(4) Check if the wire thickness is enough.

(5) Check if the output voltage control (V.adj) is properly adjusted. OVP might be trigged and output is shut down.

(6) If use function of the Remote ON/OFF control, check if the Remote ON/OFF control connector is not opened.

If in open condition, power supply will not output.

(7) Check if the built-in FAN is not stopped. Is FAN stopped by something irregulars or etc?

If FAN stops, the PF signal turn “High’’ level and OTP might be activated.

(8) Power supply has ventilating holes on the front and back panels. Check if there is any irregulars or dust, etc.

(9) Is the chassis of power supply hot abnormally? The output is shut down by OTP operation.

Please re-input after the unit to cool down sufficiently.

(10) Check if the output current and output wattage does not over specification.

(11) Audible noise can be heard when input voltage waveform is not sinusoidal.

(12) Audible noise can be heard during dynamic load operation.

11. Warranty Period

This product is warranted for a period of 5 years from the date of shipment.

For damages occurring at normal operation within this warranty period, repair is free of charge.
