Fixed Thyristor/SCR Switches

Overview

Fixed Thyristor/SCR switches handle high-voltage, high-peak-current applications such as piezo and flash lamp drivers, crowbar circuits, and surge generators, providing rapid, reliable switching while keeping your control systems isolated.

Features and applications

Customised voltages up to 150 kV for flexible high-voltage testing across applications
Peak pulsed current up to 100 kA for high-energy rapid-rise and discharge events
Extremely high di/dt for precise simulation of fast electrical pulses
Suitable for piezo drivers, flash lamp drivers, crowbar circuits and surge generators

Detail

The Silicon Controlled Rectifier handles high surge currents, ensuring your systems operate reliably under peak loads. Interference-proof signal conditioning monitors voltage, frequency, and temperature, while fault signals alert you immediately. Up to 50 modules can be paralleled to scale current for your needs, and the SCR delivers stable energy until current drops below holding level. Efficient casing and optional cooling fans optimise continuous performance, keeping your system safe, reliable, and fully under your control.
