Watlow has manufactured solid state power controllers for
over thirty years. Watlow’s POWER SERIES represents the
latest in SCR power controller technology. This microproces-
sor-based product offers features and application flexibility
unmatched by any other SCR power controller on the market
today.
Capabilities of Watlow’s POWER SERIES controllers 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.The 50/60Hz
independent operation allows utilization almost everywhere
in the world without special calibration considerations. Serial
communication utilizing Modbus
protocol provides 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 these benefits are in a
touch-safe package that can be quickly and easily mounted
in your control cabinet.
