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 1 V can be dropped
in each load lead. The drop in the load
leads subtracts from the voltage available
for the load.
Settling Time: Less than 90msec for the
output voltage to change from 1% to 99%
or vice versa following the receipt of
VOLTage or APPLy command via direct
GPIB or RS-232 interface.
Product Regulation:
Designed to comply with UL3111-1;
certified to CSA 22.2 No. 1010.1; conforms
to IEC 1010-1; complies with EMC
directive 89/336/EEC(Group1, Class A)
OVP Accuracy: 0.5% + 0.5 V, activation
time: ≥3 V, <1.5 ms, and <3 V, <10 ms
Isolation: ±240 Vdc
Stability: Voltage <0.02% + 2 mV;
Current <0.1% + 1 mA
Temperature Coefficient: <0.01% + 3 mV,
