D-C Isolation Voltage 500V d-c
Enable/Disable Output Power Using front panel or via the Digital Bus.
Polarity Reversal
(MR and MGR models only) Built-in polarity reversal power & sense relays.
Protection
Overvoltage Tracks programmed voltage, crowbars output & turns off input circuit
breaker.
Overcurrent Tracks programmed current, crowbars output & turns off input circuit
breaker.
Overtemperature Monitors heatsink temperature, crowbars output & turns off input circuit
breaker.
External Polarity
Reversal Built-in diode protects unipolar supply output.
Power Loss Detects loss of a-c input power, disables output & turns
off input circuit breaker.
Overvoltage or
interruption
between Power
and Sensing Leads MR and MGR Models:
Output voltage and current programmed to zero
and output relays opened.
M and MG Models:
Output voltage and current programmed to zero
and/or output crowbar activated and input circuit
breaker turned off
