3.2 Basic operation
There are two different modes for the unit: constant voltage (CV)
mode, and the constant current (CC) mode. Before starting to use the
unit, determine which mode is to be employed, and select the proce-
dure suitable for the selected operation mode.
• To protect the load, preset the OVP trip point for
either operation mode.
3.2.1 OVP(Over Voltage Protection) trip point preset-
ting
The overvoltage protection (OVP) function protects a load from
unexpectedly high voltage. If the OVP function is activated, the
"ALM" (alarm) LED on the control panel lights up, and output is shut
down. To release the alarm, turn off the OUTPUT switch and turn on
the POWER switch again. In this case, lower the output voltage pre-
set value. Otherwise, the OVP function is re-activated when the
OUTPUT switch is turned on.
• The OVP trip point is factory-preset to approx. 110 %
of the rated output voltage of the unit. When using
the unit, preset to an OVP trip point suitable for the
load.
• To turn on the POWER switch again after OVP has been acti-
vated, wait for at least 3 seconds after cutting off the output,
then turn on the POWER switch. Otherwise, the output cut-
off circuit may remain latched, disabling the output.
• If the OVP function is activated, the 700W and 1000W mod-
els turn off the POWER switch when output is shut down.
