System self-test
This power supply is equipped with a liquid crystal display for displaying the output
of voltage and current. A 5-digit voltage and a 5-digit current could show the actual or
setting value of a selected supply simultaneously. And the liquid crystal display can
show the current mode of power supply
。
Connections to the power supply’s output and to chassis ground are made to binding
terminals on the front panel. The Sense terminals can remotely sample the power
supply’s voltage. The positive and negative terminals of each output can be grounded,
or kept a certain voltage with the chassis ground. But voltage between each output
and the chassis ground should be kept within ±240 Vdc. The power supply is provided
with a detachable 3-wire grounding type power cord. The AC line fuse is on the rear
panel. It can be extracted for replacement when needed.
The power supply can be calibrated from the front panel directly without opening the
cabinet. Correction factors are stored in non-volatile memory. You can guard against
unauthorized calibration by using the “Standard” calibration protection function.
