Description
Control Systems 662F-22-031-00 Series 662 Power Control 50A 208VAC SCR
The Control Systems Research Series 662 is a solid-state SCR (silicon controlled rectifier) power control designed for proportional load control of resistive or inductive industrial loads. The 662F-22-031-00 is rated at 50 amps and 208 VAC. Built around a thyristor-based switching circuit mounted to a large integral aluminum finned heat sink, the Series 662 provides phase-angle or zero-crossing power regulation without mechanical contacts, making it well suited for applications requiring smooth, repeatable power delivery to heating elements or similar loads. A prominent "Caution High Voltage" label is affixed to the top of the unit.

Applications
The Series 662 SCR power controls from Control Systems Research were designed for industrial process heating and load-control applications — most commonly used to regulate AC power to resistance heating elements, infrared heaters, heating platens, and similar resistive loads in manufacturing and laboratory environments. SCR-based power controls like the Series 662 became the standard in industrial temperature control systems from the 1970s through the 1990s, replacing mechanical contactors and variable autotransformers due to their solid-state reliability, absence of moving parts, and the ability to perform smooth phase-angle firing for precise power modulation. They are commonly found in plastics processing equipment, industrial ovens and furnaces, semiconductor fabrication support systems, and general process control panels. Units of this type continue to be used in legacy industrial systems where replacement-in-kind is preferred over control system redesign. The integral finned heat sink is characteristic of open-frame SCR power controls designed for panel or chassis mounting within a ventilated enclosure.
This Control Systems Research 662F-22-031-00 Series 662 Power Control has been inspected and is in good used condition. It was pulled from a working environment where it was in active use. The unit's aluminum finned heat sink shows surface oxidation and general wear consistent with industrial service. The enclosure and SCR module body show typical scuffing and age-related discoloration. Wiring leads are present and intact. The nameplate is legible.
