Crydom Solid State Relays (SSRs) are widely used in temperature control systems. They are primarily used to switch motors, heaters, and valves in industrial and domestic heating systems, industrial and domestic air conditioning systems, refrigeration units, food heating systems, and aircraft heating and air conditioning systems.

When Random Turn-on Crydom SSR’s are utilized for phase angle controlling, more accurate control of resistance heaters can result.

The Crydom MC series of all-in-one microprocessor controlled / power SSR modules, direct temperature sensing and control can be accomplished by one product using the Crydom MCTC product line.

In addition, the Crydom MCPC proportional control/SSR module and the MCBC burst control/SSR module offers an alternative method of controlling resistance heating for closed loop control, or for users that already have sensing available.
