Over-voltage Protection:
Accuracy 0.25% + 0.25 V 0.25% + 0.15V 0.25% + 0.3V
Accuracy with Option 761 0.25% + 0.25 V 0.25% + 0.45V 0.25% + 0.6V
Accuracy with Option 760 - 0.25% + 0.45V 0.25% + 0.6V
Maximum setting 55 V 22 V 66 V
Response time
50 µs from occurrence of over-voltage condition to start of output shutdown
Output Ripple and Noise:
(PARD)
CC rms: 2 mA 10 mA 4 mA
Common Mode Noise:
(from 20 Hz – 20 MHz; from either output to chassis)
rms
500 µA 500 µA 750 µA
peak-to-peak < 2 mA < 2 mA < 3 mA
Remote Sense Capability:
Outputs can maintain specifications with up to a 1-volt drop per load lead.
The load lead drop reduces the maximum available voltage at the load.
Series and Parallel Operation:
Identically rated outputs can be operated directly in parallel
or can be connected for straight series operation..
Minimum Output Turn-On Delay:
(Time from when any Output On command is received until the output starts
turning on)
Without relay option 25 ms 18 ms 18 ms
With relay Option 760 51 ms 44 ms 44 ms
1
Correction On compensates for current flowing into the output capacitor during voltage transients.
2
Stated values apply when the load resistance is at or close to zero. To determine the frequency for larger resistance values, refer to the
User’s Guide under “Measurement System Bandwidth”.
3
Modules can discharge the specified capacitive load from full scale to 0V at a rate of 4 times/second.
