HVP 1000/200

Product catalog summary

Overview: The HVP 1000/200 is a high voltage pulser designed for driving Piezocomposite Actuators or similar loads with high charging currents in a pulse-wise, square-wave mode. It is particularly suitable for applications requiring rapid actuation.

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 200 A to flow briefly, rapidly increasing the voltage at the actuator.

Special Features:

High charging current for minimal rise times.
Option to use an ohmic resistor to adjust rise time.

Applications:

Material testing
Sensor calibration
Rapid actuation of ultra-fast valves

Technical Specifications:

Output Voltage: +40 to +1000 V
Max Current: 200 A
Charging Resistor: 5 Ω
Input Voltage Range: 0 to +5 V (external), LOW = 0; HIGH = 5 V (MOD.IN)

Monitor Output Voltage Range: 0 to +10 V
Mains Voltage: AC 230 ±10% @50/60 Hz
Dimensions: 260 x 160 x 270 mm (10.2 x 6.3 x 10.6 inches)

Additional Features:

LEMO and SLS200 plug options for actuator connection.
BNC plug for input and monitor output.
Integrated safety features including automated voltage output shutdown in case of overheating or overload.

Catalog excerpts

Voltage amplifier for pulse generation Concept: The high voltage pulser HVP 1000/200 has been designed to drive special Piezocomposite Actuators or other suitable loads with very high charging currents for pulse-wise operation in a kind of "on-off" square-wave mode. Specials: The basic principle of the HVP 1000/200 is the charging of a capacitor (C»100pF) with the necessary voltage. If triggered the capacitor will be disconnected from the power supply and discharged instantly by the Piezocomposite Actuator. A current of 200A flows for a short time. The voltage at the Piezocomposite Actuator increases in a few ps on the pre-set value. The Piezocomposite Actuator can be connected via LEMO or laboratory plugs (SLS200). Alternative at the SLS200 plugs an ohmic resistor can be applied to adjust the rise time. Product highlights: • Very high charging current for shortest rise times • Alternative ohmic resistor to adjust the rise time Application examples: • Material testing • Calibration of sensors • Rapid actuation of ultra fast valves
