Arc Quench: An arc quench feature provides sensing of each load arc and quickly inhibits the HV output for
approximately 20 ms after each arc.
Arc Count: Internal circuitry senses the number of arcs caused by external load discharges. If the rate of consecutive arcs exceeds approximately 2 arcs per second for at least five arcs, the supply will turn off for approximately 2.5 seconds to allow clearance of the fault. After this period, the supply will return automatically to theprogrammed output voltage value with the voltage rise time constant indicated. If the load fault still exists,
the above cycle will be repeated
Latching Arc Count: Same as Arc Count with the exception that the output will be latched off rather thanrecover automatically after 2.5 s. The Arc Fault is reset by cycling HV Enable OFF/ON either in LOCAL or
REMOTE control mode or by cycling AC Power OFF/ON.
