HTS-300 solid-state switches generate precise high-voltage pulses with amplitudes of up to 30 kV as needed for example in pulsed electrostatic deflection and acceleration systems. HTS-300 are perfect for generating high voltage pulses with a very fast leading edge and a highly stable and ripple-free pulse top, but without special requirements regarding the trailing edge.

In contrast to conventional high-voltage switches like gas discharge tubes or electron tubes, HTS switches do not need heating power or complex drive circuitries. They show a very short recovery time, low jitter and high-reliability typical for semiconductor devices. The power part of the switching modules is made up of a large number of MOSFET connected in parallel and in series which are absolutely synchronously controlled by a special driver. Due to the galvanic isolation the devices can be used as high-side switches for positive as well as for negative voltages. The modules are protected from thermal overload by means of an internal temperature sensor. Further protection is afforded against too high a signal frequency and unsufficient auxiliary supply. All fault conditions will be indicated at the fault signal output (pin 4) as a logical "Low" signal. At the same time the switch will be turned off until correct operating conditions are ensured.
