Description

The front panel includes a VFD for displaying the output voltage and
current. Two 4-digit voltage and current meters accurately show the actual
or limit values of a selected supply simultaneously. Three meter selection
keys choose the voltage and current of any one output to be monitored on
the display.
Connections to the power supply's output and to chassis ground are made to
binding posts on the front panel. The +25V and -25V supply's outputs share a
common output terminal which is isolated from chassis ground. The positive
and negative terminals of each output can be grounded, or each output can
be kept within ±240 Vdc from the chassis ground. The power supply is
shipped with a detachable, 3-wire grounding type power cord. The ac line
fuse is an extractor type on the rear panel.
The power supply can be calibrated from the front panel directly or with a
controller over the GPIB or RS-232 interface using calibration commands.
Correction factors are stored in
non-volatile
memory and are used during
output programming. Calibration from the front panel or a controller
eliminates the need to remove the top cover or even the need to remove the
power supply from your system cabinet. You can guard against unauthorized
calibration by using the

calibration protection function.
