Power Switch
To enhance the safety of the power supply, the protect function
based on an AC power relay is provided separately from the power
switch. The AC power relay can be turned on/off from a external
signal while leaving the power switch in the on position.

Function
OVP Presetting
Pressing the OVP switch displays the OVP (Over Voltage
Protector) trip voltage on the voltmeter. This lets you perform
setting and verification without interrupting operation, even while
the output is on.
Digital Display
A bright, easy-to-read red LED shows the voltage and current
simultaneously. The voltage can be measured in 3-1/2 digits (auto-
ranging) with a maximum display resolution of 10 mV with all
models. The current can be measured in 3-1/2 digits (auto-
ranging) with a maximum display resolution of 10 mA with models
with rated cur rents below 50 A, and in 3-1/2 digits with a
maximum display resolution of 100 mA with models with rated
currents of 50 A or more (3-digit, 1 A resolution with the PS10-
210).
Output Switch
The output switch uses an electronic switch system to eliminate
chattering or noise. The switch is set automatically to off when
power is switched on so that unexpected output is not produced.
The output can be fixed to on or the output on/off switching can
be remote controlled with an external signal according to the DIP
switch selection.
Limit Switch
Pressing the LIMIT switch displays the constant voltage setting
value on the voltmeter and the constant current setting value
(current limiting value) on the ammeter. This makes setting and
verification possible without interruption, even while the output is
on.
