The A1P and A3P Phase angle proportional controls. No temperature or power cycling. Fast response - 1/2 of power line cycle. Increase heater life up to 7x. Unique mono-couple design assures phase tracking for life (A1P). No phase restrictions and independent zero and span adjustments for each phase (A3P). Optional voltage and current limit.
The A3Z and A1Z zero voltage switches. Independent automatic syncronization, no phase rotation restrictions, fast, wide-ratio auto-variable time based proportioning, and superior firing resolution. No third line hook up for A3Z.

SCR Power Controls
SCR Power Controls
Reliable - Oversized, isolated SCR's with MOV, DV/DT protection and I2T Rectifier fuses standard. No phase restrictions. No transformers to wire up. No field calibration needed.
Versatile - Phase Angle Control for IR Quartz heaters. Voltage and current limit gives smooth Proportional control. Zero voltage switched, with fast, wide-ratio, auto-variable time based proportioning and no 3rd line hookup required. On/Off controls replace mechanical and mercury contactors. SCR's can cycle 1,000,000,000 times or more. No HazMat problems, no arcs or mechanical wear.
Compact - Space saving integrated thermal-mechanical designs.
Custom and Multi-zone configurations available.
Affordable - Large family of controls lets you choose what is right for your needs.
Delivery - Stocked for overnight delivery.
