DIN-A-MITE B Power Controller

Configure ProductRequest Information
The DIN-A-MITE B power controller provides a low-cost, highly compact and versatile solid state option for controlling electric heat. The DIN-A-MITE B capabilities include single-phase and three-phase zero-cross switching up to 40 and 22 amperes, respectively at 600VAC (see rating curve). This controller's design includes proper heat sinking and terminations simplifying integration into applications. DIN-rail and back panel mounting is standard on this family of controllers. The DIN-A-MITE controller is also mercury free.

Variable time base, 4-20mA process control or VAC/VDC input contactor versions are available. A shorted silicon controlled rectifier (SCR) alarm option is also available. All options are model number dependent and factory configurable. This power controller also includes 200KA short circuit current rating (SCCR) tested up to 480VAC to prevent arch flash with required fusing.
