Supplemental characteristics
for all model numbers
DC floating voltage: Output terminals
can be floated up to ±240 VDC from
chassis ground
Remote sensing: Up to half the rated
output voltage can be dropped in each
load lead. The drop in the load leads
subtracts from the voltage available
for the load.
Command processing time: Average time
required for the output voltage to begin to
change following receipt of digital data is
20 ms for the power supplies connected
directly to the GPIB
Output programming response time: The
rise and fall time (10/90% and 90/10%)
of the output voltage is less than 15 ms.
The output voltage change settles within
1 LSB (0.025% x rated voltage) of final
value in less than 60 ms.
Down programming: An active down
programmer sinks approximately
20% of the rated output current
Modulation: (Analog programming
of output voltage and current)
Input Signal: 0 to -5 V
Input Impedance: 10 kΩ nominal
