Line regulation
(% of output offset)
(Change in output voltage and
current for any line change within
ratings)
Voltage 0.01% 2 mV
Current 0.01% 250 A
Programming resolution Voltage 1 mV
Current 0.5 mA
Readback resolution Voltage 0.5 mV
Current 0.1 mA
Front panel resolution Voltage 1 mV
Current 1 mA
Transient response time 50 s for the output to recover to within 15 mV following a change in
the output current from full load to half load, or vice versa.
Command processing time Average time for the output voltage to begin to change after receiving
the digital data when the power supply is connected directly to the
GPIB or RS-232 is less than 100 ms
OVP and OCP accuracy
(% of output offset)
Overvoltage
protection (OVP)
0.5% +0.5 V
Overcurrent
protection (OCP)
0.5% +0.5 A
Activation time
(Average time for the output to
start to drop after OVP or OCP
condition occurs)
OVP • <1.5 ms when the trip voltage is equal or greater than 3 V
• <10 ms when the trip voltage is less than 3 V
OCP <10 ms
[1] Accuracy specifications after a 1-hour warm-up period with no load and calibration at 25 C.
