Product Description
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.
