Inrush current <= maximum operating current, Ground Leakage current <= 5 mA. Separate M6 ground stud (metric size) on the rear panel.
Output
0kV to 3kV. Output voltage overshoot smaller 0.1% of full scale 3kV, measured at the 5 meter-long cable end output.
Output power
About at 100 % of rated voltage (charge 21µF in 1ms from 0V to 3000V), exact value determined by critical performance parameters
Efficiency
> 85 % .
Input Protection
Phase loss detection. Equipped with a dedicated 3 phases circuit breaker.
Power factor
> 85%.

Harting type Han B Base Panel 2 Levers.
Power Functions and Performance
Parallel operation. The HVPS can be paralleled with a second (third) HVPS to provide twice (triple)output power. Input power may be parallel and HV output power may be parallel. Interlocks for each unit displayed on the input panel.
Regulation
40% to 100% scale of rate output, ±0.1% peak to peak (6V total voltage range at 3kV) for 0-600Hz as measured on the first consecutive pulse after a change in output voltage or rep rate.
Stability
<±0.1% within every 8 hours after 1 hour warm-up.
Linearity of programmed output voltage
40% to 100% scale of rate output,±1.0%.
Programming accuracy of output voltage
40% to100% scale of rate output, ±0.1% peak to peak (6V total voltage range at 3kV) for 0-600Hz measured on the first consecutive pulse after a change in output voltage or rep rate.
Autoinhibit
Adjustable self-rejection range from 10μs to1010μsfactory set self-rejection 500μs.
External Inhibit
The power supply allows external signals to control the output of the power supply for suppression. The high voltage is triggered by the light enable on the optical receiver, and the maximum external suppression time is 1010µs.
Status Indicators
Green LED for mains on,green LED for HV on. 5 red Leds for interlocks phase loss, Overtemp, Overvoltage, Short circuit, Remote Error. The corresponding LED will remain lit until the system is manually reset or until the fault condition is resolved.
