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 k Ohm nominal
ac Input: (ac input frequency 47 to 63 Hz)

Input Power: 1,380 VA, 1,100 W at full load; 120 W at no load
GPIB Interface Capabilities: SH1, AH1, T6, L4, SR1, RL1, PP0, DC1,
DT1, E1, and C0. IEEE-488.2 and SCPI-compatible command set.
Regulatory Compliance: Listed to UL 1244; conforms to IEC 61010-1.
