RISTAL CONTROLS is changing the SCR world by introducing the smallest and the most innovative SCR on the market.

Cristal's sealed SCR controllers are safer and less prone to problems — Unlike competitive products, which have all their circuits exposed to dust, humidity, vibration and other environmental conditions, Cristal's SCR power controllers are designed to withstand the test of time.

For example, there is no possibility of short-circuits created by dust built-up on circuits in a humid environment. This is an important consideration in industrial applications. Also, the heat sink is completely isolated from the power source. You can touch it live without risk of shock.

Installation is faster and easier — Forget those bulky SCR power controllers that need oversize holes in your control panel. Forget these ugly heat sinks outside the control boxes. Our super clean design is a breeze to install, and requires only a few ventilating louvers.

A full range of products for all applications — Up to 750 Amps, 1 or 3 phases, Zero Crossing, Phase Angle, SSR, Step Controllers, with or without enclosure. And they are all available with NEMA-4 or ventilated enclosure for remote installation. Special orders are welcome.
