POWER SERIES™

Microprocessor-Based SCR Power Control Designed for Application Flexibility

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 and solid state controller on the market today.

Watlow's POWER SERIES solid state 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 solid state controllers are UL® listed and C-UL® recognized, ensuring that they meet world safety and operational standards.
