Pulse Amplifier/Puff Valve Driver

The EHT Pulse Amplifier offers a simple way to generate high voltage pulses up to 800 V. This unit includes four independently triggered channels and features a dual voltage isolated internal supply that can rapidly actuate valves, and then hold them open continuously. The user can choose whether to connect an external higher power voltage source up to 800 V, or can elect to use the internal power supplies. This module is controllable via fiber or BNC input, at frequencies up to 50 kHz.
