Thermostats for UPS Battery Back-Up Systems from ATC Semitec

When a power-cut hits a company, they need to be sure that their UPS system performs immediately and for as long as possible until mains power is re-established.

The life of a battery back-up system is partly dependant on its stable temperature control which is often achieved using electronic means. As an alternative to electronic sensors, the Matsuo MQT thermostat offers UPS system installers a simpler and more cost-effective solution.

Matsuo thermostats have a unique twin-bimetal system that creates a control which is capable of switching over 1 million cycles. Accuracies of ±1.5K and differentials down to 3K±1K are readily available, with repeatability as small as ±0.2K. Basically they function on a par with electronic controllers.

The thermostat’s IP64 plastic housing can be readily fixed to the side of a battery and so each one can be safely monitored.
