Supplemental Characteristics
for all model numbers
dc Floating Voltage: Output terminal can
be floated up to ±60 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 at
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 power supplies
connected directly to the GPIB.
Modulation: (analog programming of
output voltage and current):
Input Signal: 0 to –5 V for voltage,
and 0 to +5 V for current.
Input Impedance: 30 kΩ or greater.
ac Input (47 to 63 Hz): 180 to 235 Vac
(line-to-line 3 phase) 36 A rms maximum
worst case, 28 A rms nominal;
360 to 440 Vac, 18 A rms maximum
worst case, 14 A rms nominal.
(Maximum line current includes 5%
unbalanced phase voltage condition).
Input Power: 9000 VA and 7950 W
maximum; 175 W at no load.
Size: 425.5 mm W x 221.5 mm H x
674.7 mm D (16.75 in x
8.75 in x 25.56 in).
See page 104 for more details.
Warranty Period: Three years.
Single-Output: 6600 W GPIB (Continued)
