2. Terminal Connecting Method

Pay attention to the input wiring. If it is connected to

wrong terminal, the power supply will be damaged.

• Input must be off when making connections.

• Connect FG terminal of input connector and mount-

able FG to ground terminal of the equipment.

• Output current of each connector pin must be less

than 5A. ( Except /T, /S models which M4 screw is

used. )

• The output load line and input line shall be separated

and twisted to improve noise sensitivity.

• Remote ON/OFF control lines shall be twisted or use

shielded wire.

• Use the input/output connector housing, terminal pin

as specified in outline drawing. Also, use recom-

mended crimping tool.

Connector housing and terminal pin is not included

with this product.

• When connecting or removing connector, do not ap-

ply stress to PCB.

INSTRUCTION MANUAL

3. Explanation of Functions and Precautions

3-1. Input Voltage Range

Input voltage range is single phase 85 ~ 265VAC ( 47 ~

63Hz ) or 120 ~ 370VDC. Input voltage which is out of

specification may cause unit damage. For cases where con-

formance to various safety specs(UL,CSA,EN) are re-

quired, input voltage range will be 100 ~ 240VAC

( 50/60Hz ).

3-2. Output Voltage Range

V.ADJ trimmer(VR51) that is nearby to output connector

is for output voltage adjustment within the range of speci-

fications. To turn the trimmer clockwise, the output volt-

age will be increased. Note over voltage protection (OVP)

function may trigger if the output voltage is increased ex-

cessively.

3-3. Inrush Current

This series has used Power Thermistor to protect the cir-

cuit from Inrush Current. Please carefully select input

switch and fuse in cases of the high temperature and re-

input the power.

3-4. Over Voltage Protection ( OVP )

The OVP function ( Inverter shut down method, manual

reset type ) is provided. OVP function operates within the

range of OVP specification.When OVP triggers, the out-

put will be shut down. The input shall be removed for a

few minutes, and then re-input for recovery of the output.

OVP setting is fixed and not to be adjusted externally.

3-5. Over Current Protection ( OCP )

Constant current limiting, automatic recovery. OCP func-

tion operates when the output current exceeds OCP speci-

fication. The output will be automatically recovered when

the overload condition is cancelled. Do not operate over-

load or dead short conditions for more than 30 seconds,

which could result in damage or insulation failure.

3-6. Over Temperature Protection ( OTP )

For /OTP, /JOTP, /TOTP, /SOTP models, OTP circuit is

built into the power supply to prevent power supply from

damage when ambient temperature over the specification.

3-7. Output Ripple & Noise

The standard specification for maximum ripple value is

measured according to measurement circuit specified by

JEITA-RC9131. When load lines are longer, ripple be-

comes larger. In this case, electrolytic capacitor, film ca-

pacitor, etc. might be necessary to use across the load ter-

minal. The output ripple cannot be measured accurately if

the probe ground lead of oscilloscope is too long.

3-10. Peak Output Current

For ZWS150PAF series, the peak output current should

satisfy the conditions below:

1)Should not exceed the rated peak current in the

specifications.(eg. 12A for ZWS150PAF-24)

2)Duty cycle of the peak output current should be < 35%,

and operating time of peak output current is less than 10

seconds. If the power supply is operated under convec-

tion cooling, and ambient exceeds 50oC, the following

operating period for peak current is recommended.

Ambient Temperature ( C) Peak current operating time

-10 ~ +50 C within 10 seconds

+50 C onwards within 5 seconds

3)The relation between peak output current with maximum

average output current is defined as below:

Ip = Peak output current

Im = Minimum output current

D = Duty cycle, τ/T

τ= Peak output current operating time

T = Period

Io = Maximum allowable average output current of speci-

fications (Io should be average load after derating at

various mounting and ambient temperature)

Formula:

ZWS150PAF: 1.4 Io2> Ip2D + Im2(1-D)

Example I : For ZWS150PAF-24 at Ta =60 C,Mounting A,

Max Io =4.41A (after 70% Derating)

1.4 Io2> Ip2 D + Im2(1-D)

(A): In case of Im =0, Ip =12A,

D<18.9%

(B): In case of Im =2A, Ip =12A,

D<16.6%

Example II : Following table illustrate some peak load op-

eration examples for ZWS150PAF-24.

Please note that the actual Io in peak load operation is low .

3-11. Remote ON/OFF Control

Remote ON/OFF control (CN2,CN52) function is avail-

able. Using this function allows the user to turn the output

on and off without having to turn the AC input on and off.

Remote ON/OFF control can be used by following 2 modes.

However, for Cover and Chassis type (eg. ZWS150PAF/A,

/JA, /TA, /SA) cannot be used.

INSTRUCTION MANUAL

Using CN2

It is controlled by short or open between +R & -R of CN2.

CN2 is provided in the primary circuit for ON/OFF control

by means of a switch or other device. When using this con-

nector, which is considered to be electrically connected to

the mains input voltage, all the requirements of EN60950

must be met with respect to the connector, wiring and

switch etc.

In particular:

1) Basic insulation must be provided between the

ON/OFF control circuit and earth.

2) Reinforced insulation must be provided between the

ON/OFF control circuit and any secondary circuit or

accessible part.

3) Wiring must be routed such that damage to the insula-

tion of the wire or additional sleeving cannot occur.

4) The switch must meet requirements for reinforced in-

sulation from the ON/OFF control circuit to actua-

tor/ac-cessible parts.

[CN2] The control mode is shown below.

+R & -R Terminal condition Output condition

Short ON

Open OFF

*Using CN52

At first, remove short piece of CN2.

It is controlled by the voltage applied to +R and –R. This

circuit is in the Secondary ( output ) side of the power sup-

ply unit. Do not connect in the Primary ( input ) side. And

this circuit is isolated from the output by a photo-coupler.

3-12. Isolation Test

Isolation resistance between output and FG (Chassis) shall

be more than 100MΩat 500VDC. For safety operation,

voltage setting of DC isolation tester must be done before

the test. Ensure that the it is fully discharged after the test.

3-13. Withstand Voltage

This series is designed to withstand 3.0kVAC between in-

put and output, 2.0kVAC between input and FG (Chassis)

and 500VAC between output and the FG (Chassis) each

for 1 minute. When testing withstand voltage, set current

limit of the withstand voltage test equipment to 20mA

( Output - FG (Chassis) : 100mA ). The applied voltage

must be gradually increased from zero to the 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 out-

put as follows.
