2． Features

2-1

Input voltage

・ Input voltage range is single phase alternating

current. 85～264Vac(47～63Hz).

・ We recommend that you do not use this power

supply unit outside of it's normal intended use in

order to avoid any damage or malfunctions.

2-2

Output voltage setting

・ You can adjust +Vout by using Output Voltage

Adjustment Potentiometer that is next to the

connector (CN501).

・ You can increase output voltage by turning clockwise.

If you need decrease, you can turn it the other way.

・ Please use it within the following range when you

adjust the output voltage.

・Within +/- 10% rated output voltage.

・Do not use maximum output power.

・ Do not exceed rated output current.

2-5

Over-Voltage Protection(OVP)

・

It detects when the output voltage exceeds by some

reasons, and the output is intercepted at once.

・

When it works once, the over-voltage protection

continues the output interception while the input is

supplied.

・

Turn it on again after a few minutes after intercepting

the input when resetting it.

・

Note that the output voltage might be abnormal when

you turn it on again. (In this case, the over voltage

protection works again. )

2-7

Over Temperature Protection (OTP)

・

It detects internal components temperature abnormally

getting higher, then turn off the output.

・

Once it detects and stops output, it stops supplying the

output even AC input supplies.

・

In order to reset this, please disconnect AC input, then

confirm well cooling down the temperature inside the PSU

after several minutes. Then please apply AC input. Also

please confirm the forced air convection would well enough

to meet the air flow condition.

2-3

Inrush Current

・ The inrush current limiting circuit is built-in.

・ The inrush current limiting circuit might released it

when the input re-turning on time is short, because

SCR is used for the inrush current limiting. So turn it

on again enough after time.

・ The first inrush current and the second inrush

current flow because it adopts SCR method for the

inrush current limiting circuit.

2-4

Over-current Protection(OCP)

・ The over-current protection works and the output is

intercepted when becoming 110% or more of the

output current ratings.

・ Remove the factor of the overload, and turn on the

input again after a few minutes of cutting when

resetting it.

・ Please avoid operation in the over-current state

for 10 seconds or more.

It will cause damage or isolation failure.

2-6

Remote Sensing

・

Please use within 0.3V voltage drop range to adjust.

・

Then, please set up the output voltage range won't

exceed voltage range we specify.

・

Please twist the wires and install just besides in parallel

with wires for load as shown below.

Power

・

Note: We connected with wires between Pin#1 & Pin#2,

Also Pin #3 & Pin#4 as a default settings when we ship

from factory. This setting is for the customers who won't

use remote sensing feature. So, if you need to use this

feature, 1) Please remove the existing wires 2) Use

twisted cable for this feature to use shown as above.
