C7

HV switch with variable on-time, Thyristor / MCT  


 

Versatile HV switch with true relay character On-time controllable by TTL signal Low turn-on losses High surge current capability  200 Amps turn-off capability 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 41-300-MCT:  HTS = HV Thyristor Switch, 4 = 4 kV,  1 = variable on-time, 300 = 3000 Ampere, MCT = MOS Controlled Thyristor
