APPLICATION
HOW TO S E T OVERVOLTAGE PROTECTION
(OVP) LEVEL
Keeping the OVP CHECK switch depressed, the overvoltage
protection level indicated on the voltmeter.
(1) Turn off the OUTPUT switch.
(2) Keeping the OVP CHECK switch depressed, screw the
OVP adjuster with a screwdriver and set an overvoltage
protection level.
(3) Turn on the OUTPUT switch with no load connected (the
indicator lights). Raising the output voltage gradually,
check if the power switch turns off at the preset over-
voltage protection level.
(4) Set the overvoltage protection level at the maximum
reading of the output voltmeter if overvoltage protection
is not necessary.
USE OF REAR-PANEL TERMINALS
The output and control terminals shown above are equipped
on the rear panel. These terminals may be used to perform
remote sensing, remote control of output voltage and output
current, master/slave control operation with power supply
connected in series or parallel.
REMOTE SENSING
When the device is connected to a load, voltage drops due to
contact resistance at the output terminals and resistance of
conductors. Remote sensing is performed to compensate for
the voltage drop.
1) Turn off power.
2) Remove the short bars © -
(£s)
and © - (Js).
3) Connect and to the load. Use a two-core shield
cable for these sensing lines and connect the shield line to
© output.
