Protection 

All outputs are protected from arcs in the load and continuous short circuit.  

The unit will withstand maximum voltage arcs with an average repetition rate of up to 0.1Hz.  

If the Accelerator has more than 8 arcs in a nominal 10 second period the unit will shut down. If there 
are less than 8 arcs the unit will continue to operate. Arc events less than 100ms from the previous 
event will be ignored.  

A shutdown event maybe reset by toggling the ‘Outputs 1, 2&3 remote on/off’ level off and on again or 

toggling the input power off and on again. 

All low voltage inputs are protected against over voltage (up to 30V) and negative input voltages (up to 
-30V). 

The maximum output voltage, even under single fault conditions, is 40kV.
