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
directlytotheGPIB
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
1LSB(0.025%xratedvoltage)offinal
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 k nominal
