Options
AQ - Arc Quench: An arc quench feature provides sensing of each load arc and quickly inhibits the HV output forapproximately 20 ms after each arc.
AC - 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 the programmed output voltage value with the voltage rise time constant indicated. If the load fault still exists, the above
cycle will be repeated
ETH - Ethernet: Virtual RS-232 COM port over Ethernet network. (Requires compatible OS (eg Windows) for COMdrivers). RS-485 feature is disabled on units with Ethernet option.
SS - Slow Start Ramp: Specify standard times of 5, 10, 15, 20, or 30 seconds, ±20%.
