C1

HV switches with variable on-time, general purpose, MOSFET  


  

Versatile HV switch with true relay character On-time controllable by TTL signal Negligible dynamic switching losses due to fast transistion time Robust regarding overload and voltage reversal Excellent dv/dt immunity against HV transients

    

Note: The model number contains coded information about voltage, current and turn-on behavior.  The first digits stand for the voltage in kV, the last digit before the dash indicates the turn-on behavior (0 = fixed on-time, 1 = variable on-time). The digits after the dash indicate the current  in Amperes x10. Special features are coded by the letters after a second dash.

Example HTS 31-06-C:  HTS = HV Transistor Switch, 3 = 3 kV,  1 = variable on-time, 06 = 60 Ampere, C = Compact.
