HIGH ENERGY SPARK GAP DEVICES
TG Legacy Series
DESCRIPTION
CP Clare’s TG Legacy Series of two electrode sparkgaps excel in applications that require the efficient transfer of high voltage, high energy pulses and DC overvoltage protection for magnetrons, diodes, capacitors, etc. The TG Legacy Series also includes three electrode triggered sparkgaps (cold cathode thyratrons) for switching high levels of stored energy in fractions of a microsecond, on command, using low energy control pulses.
FEATURES
