FEATURES
· Linear control for low noise: 100 micro-
volts typical in voltage mode; and high
precision: 0.0005% source effect {regulation}
in voltage mode.
· Voltage and current control with equivalent
performance. A high speed mode allows
fast-recovery current-controlled stabilization
into a varying load.
· Overvoltage and overcurrent settings
individually programmed by the front
panel keypad or remotely by the bus with
a programmable delay to allow for reactive-
load transients.
· A manually set overvoltage crowbar
monitors the output to protect sensitive
loads. This setting is done only from the
front panel and cannot be modified by the
keypad or GPIB.
