SPECIFICATIONS
dc Floating Voltage: Output terminals can be floated up to
±240 Vdc maximum from chassis ground
Remote Sensing: Up to two volts dropped in each load lead. Add 2
mV to the voltage load regulation specification for each one volt
change in the positive output lead due to load current change.
Command-Processing Time:
Average time required for the output
voltage
to begin to change following receipt of digital data is 4
ms for the power supplies connected directly to the GPIB.
(Display disabled.)
Output-Programming Response Time: The rise and fall time (10/90%
and 90/10%) of the output voltage is less than 2 ms (400 µs in
fast mode). The output voltage change settles within 1 LSB
(0.025% x rated voltage) of final value in less than 6 ms
(2 ms in the fast mode).
GPIB Interface Capabilities: IEEE-488.2, SCPI command set and
6630A Series programming compatability
Measurement Time: Average time to make a voltage or current
measurement is 50 ms.
Input Power (full load): 3.5 A, 250 W
Regulatory Compliance: Complies with EMC directive 89/336/EEC
(ISM 1B). See page 73 for more information.
Warranty Period: Three years
* When programming in the 6630A Series language compatibility mode.
Size: 425.5 mm W x 88.1 mm H x 364.4 mm D (16.8 in x 3.5 in x 14.3 in).
