The STOM2 is a microprocessor based trigger module capable of driving most power thyristors. The STOM2 has two modes of triggering control, phase-angle and burst-firing either can be selected separately. The module can also be used for soft-starting in phase-angle mode and it will automatically switch to burst-fire mode when the control signal has reached a preset level. The STOM2 has a soft-start from power up which can be set from 0-30 seconds. The signal inputs are fully isolated operating from either 0-5V dc or 4-20mA – accepting signals from temperature controllers, manual potentiometers, microprocessors etc.

Suitable for most resistive and inductive loads including ovens, moulders, and dryers Ideal for unusual heating loads which have very low resistance when cold.

Energy saving Soft start-facility Phase-angle or burst-firing
Simple wiring Standard 80mm fixing Solid-state reliability
