 Remote ON/OFF Control (Optional)
Remote ON/OFF control function is available as option
with model name followed by "/R". Using this function al-
lows the user to turn the all outputs on and off without
having to turn the AC input on and off. 基板上のコネクタ
trolled by the voltage applied to +R and -R. This current is
in the secondary (output) side of the power supply unit. Do
not connect in the primary (input) side. And this circuit is
isolated from the output by a photocoupler.
 Insulation Resistance Test
The insulation resistance value is above 100MΩ at
Please use the mounting hole as:
and insert the spacer (MAXφ6.0) of height over 8mm to
lift the unit.
The vibration spec is the value taken when the unit is
raised by 8mm spacers.

Considering the safety, please set the voltage value of DC
insulation meter before the test, and well discharge the in-
sulation meter after the test.
 Withstand Voltage Test
ZWS300 is designed to be able to withstand 3kVAC
(10mA) 1minute between input-output, 2kVAC (10mA)
1minute between input-FG, and 500VAC (100mA) 1 min-
ute between output-FG.
Please set the limit current value of the withstand voltage
tester as mentioned above before doing test.
Please elevate the applying voltage gradually, and lower it
gradually, too, when shutdown.
Please do not use a timer in the test.
Because when the test voltage is supplied or shutdown, an
impulse high voltage may be generated which will break
the power supply unit.
Please left 5mm space from the surfaces and left 4mm
space from the sides of PCB, especially from the solder
surface, 8mm space is necessary.
If the space is not enough, the specification of insulation
and withstand will not be satisfied.
FG should be connected to the earth terminal of the appa-
ratus.
If not, the conducted noise and output noise will increase.
