Watlow's Power Series

Microprocessor-Based SCR Power Controller Designed for Application Flexibility

For over thirty years Watlow has been manufacturing solid state power controllers. Watlow's new POWER SERIES represents the latest in SCR power controller technology. This microprocessor-based product offers features and application flexibility unmatched by any other SCR power controller on the market today.

Capabilities include single-phase and three-phase models from 65 to 250 amps. Field configurable phase angle or zero-cross firing improves application flexibility on site where you need it. 50/60Hz independent operation means you can operate almost everywhere in the world without special calibration considerations. Serial communications utilizing Modbus™ protocol allow for remote control setup, and monitoring of load status from a nearby 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 this in a touch-safe package that can be quickly and easily mounted in your control cabinet.

Agency approvals ensure a product that meets world safety and operational standards. You can be assured your power controller will be ideal wherever you choose to do business.
