Power Controls & SCRs

Power Controls have many different names.  Solid Sate Relays, SSRs, SCRs, Silicon Rectifiers, Thyristors, Zero Cross Relays ,Triac Relays and Phase Angle SCRs.

Silicon Controlled Rectifier (SCR) power controller provides a low cost, compact and versatile solid state controller option for controlling electric heat.  Basic features of the solid state controller include single-phase, three-phase/two leg, and three-phase/three leg, 24-600VAC operation. Current switching capabilities range from 12 to 800A depending on the model ordered. Variable time base, linear voltage and current process control or VAC/VDC input contactor versions are available.

Single and Three phase, phase angle firing and current limiting are also available referred to as Power Controls. All configurations are model number dependent and factory selectable. This solid state power controller includes 200KA short circuit current rating (SCCR) tested up to 480VAC to prevent arch flash with required fusing.

The Watlow family of Din-A-Mites & Aspyre SCRs can fit any heating system requirement.
