External Voltage Control
Operating Mode: The applied voltage determines the operating level within the
selected range.
Scaling: 4 Volts full scale.
Accuracy: ± 0·3% ± accuracy of selected range.
Common mode rejection: Better than –66dB.
External TTL Control
Operating Mode: The applied signal selects between Level A and Level B settings.
Threshold: + 1·5V nominal. A logic high selects Level B.
Remote Disable Input
Connection: Terminal block on rear panel.
Threshold: Apply +3 to +5 V to disable load input.
PROTECTION
Excess Current: The unit will trip into the fault state at nominally 92 Amps.
Excess Power: The unit will attempt to limit the power to approx 335 Watts; if this
fails the unit will trip into the fault state at about 360 Watts.
Excess Voltage: The unit will conduct a current pulse (to absorb inductively generated
spikes) for 1ms at 90V.
The unit will trip into the fault state at nominally 95V.
Surge suppressors will start to conduct above 120V.
Temperature: The unit will trip into the fault state if the heatsink temperature
exceeds safe levels.
Sense Error: The unit will trip into the fault state if the external voltage sense is
more than 6V below the internal sense.
Mode Switching: The unit will trip into the fault state if the mode is changed while the
input is enabled.
