Export Restrictions: Fast solid-state switches with a maximum peak current equal or higher than 500 Amperes are export restricted according to the United States law as well as the German law (dual use regulation). These goods must not be exported to third countries without a valid export permit of the US or German export authorities. An enduser statement may be required. Please consult BEHLKE.

Product Code: 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 10-70-F:  HTS = HV Transistor Switch, 1 = 1 kV,  0 = fixed on-time, 70 = 700 Ampere, F = Fast
