High Voltage / High Current Pulsers

High Voltage / High Current

Overview

The DEI Division specializes in high-performance pulsers, laser diode drivers, and high-voltage power supplies for demanding scientific, industrial, and defense applications. Designed for rapid rise times, stability, and customizable outputs, these systems support applications from particle beam modulation and time-of-flight mass spectrometry to driving high-power laser diodes. Key models include the PVX-4110 (10 kV bipolar pulse generator), PVX-4151 (±1.5 kV pulse output), the PCX-7421 (50 mA–21.5 A laser diode driver with 50 ns–500 ms pulse widths), and the EVO Series high-voltage supplies delivering up to 3 kW in a compact 2U design. Built for reliability and precision, DEI solutions ensure stable, long-term performance in critical environments.
