Temperature Control

A range of triac drive integrated circuits designed for simmerstat operations or with sense inputs for single or multiple feedback control.  

Power Control and Mains Phase Control

Phase control by OM5428 integrated circuit designed to replace the TCA280B type products, for use with modern high reliability, high sensitivity 3 quadrant or snubberless Triacs such as in the Philips Semiconductor range.

Commercial and Industrial Temperature Control

Temperature control for commercial refrigeration and beverage cooler markets, and also industrial temperature control.  Modules are designed around temperature control triac drive integrated circuits, to meet high performing management control, and maintenance diagnostic demands of this market place.

Mains Relay Switching with Contact Protection

Mains relays require special contact materials and characteristics and operational performance may be limited to give acceptable lifetime of contacts and therefore relay reliability.

The implementation of effective contact protection extends both the mains relay reliability, and the operational reliability of the circuit in which it operates.  This therefore makes the designer’s task more simple, and enables a significant overall reliability improvement and equipment lifetime.

The IES5541A introduces the capability of longer relay life, higher switching rates and significantly lower EMI interference.  This integrated circuit offers controlled mains relay drive when implemented with the typical circuit configuration and thereby offers a higher reliability solution in a wide range of controlled mains switching situations, where either sensing or logic driven inputs are used.
