HVP 300/20

Product catalog summary

Overview: The HVP 300/20 is a voltage amplifier designed for pulse generation, specifically to drive Piezocomposite Actuators with high charging currents in an on-off square-wave mode.

Concept: The device operates by charging a capacitor (approximately 100 µF) to the necessary voltage. Upon triggering, the capacitor disconnects from the power supply and discharges through the actuator, allowing a current of 20 A to flow briefly, rapidly increasing the voltage at the load.

Special Features: The amplifier offers high charging currents for short rise times and allows the use of an alternative ohmic resistor to adjust rise time. Connections can be made via LEMO or SLS200 plugs.

Applications: The HVP 300/20 is suitable for material testing, sensor calibration, and rapid actuation of ultra-fast valves.

HVP 300/20 Voltage amplifier for pulse generation Concept: The high voltage pulser HVP 300/20 has been designed to drive special Piezocomposite Actuators from piezosystem jena or other suitable loads with high charging currents for pulse-wise operation in a kind of “on-off” square-wave mode. Image: HVP 300/20 Specials: The basic principle of the HVP 300/20 is the charging of a capacitor (C»100 µF) with the necessary voltage. If triggered the capacitor will be discon- Product highlights: nected from the power supply and discharged instantly by the Piezocomposite Actuator. A current of 20 A flows for a short time. The voltage at the load increases in a few µs on the pre-set value. The load can be connected via LEMO or laboratory Alternative ohmic resistor to adjust the rise time plugs (SLS200). Alternative at the SLS200 plugs an ohmic resistor can be applied to adjust the rise time. High charging current for short rise Material testing Rapid actu
