Watlow Power Series SCR

Watlow® has manufactured solid state power controllers for over forty years. Watlow’s POWER SERIES™ is a microprocessor-based product that features application flexibility unmatched by any other silicon controlled rectifier (SCR) power controller on the market today.

Watlow’s POWER SERIES controllers include single and three-phase models from 65 to 250 amperes. Field configurable phase-angle or zero-cross firing improves application flexibility on site where needed. 50/60Hz independent operation allows utilization almost everywhere in the world without special calibration considerations. Serial communication via Modbus® RTU allows setup and monitoring of load status from a computer station or control room. On-board semiconductor fusing improves reliability by protecting the SCRs from heater short circuits. Plus, on-board heater bakeout and control diagnostics can help eliminate initial start up problems.

All these benefits are in a touch-safe package that can be quickly and easily mounted in a control cabinet. Watlow’s POWER SERIES controllers are UL® and C-UL® listed, ensuring that they meet world safety and operational standards.
