Watlow Power Series™

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.

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, optional on-board heater bakeout and control diagnostics can help eliminate initial start up problems.

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

Toughness/Reliability

TE10A thyristors can withstand momentary over currents up to 15 times the nominal rating - important when controlling short-wave infrared elements. The thyristor breakdown voltage is three times greater than the nominal operating voltage. Current derating curves as a function of ambient temperature enable TE10A units to be used up to +60°C.
