Power Switching Devices
Watlow solid state power switching devices complement the rapid
switching required by PID temperature controllers and help deliver
optimum system performance and service life. They are available in
1-phase and 3-phase/2-leg and 3-leg configurations, feature touch-safe
terminations, input indicators, zero-cross, random or phase-angle fire
options, ratings from 18 to 1,000 amperes and agency approvals including
CE and UL® 508. Various configurations offer short circuit
current ratings (SCCR) of 200,000 amperes, extensive system and heater
diagnostic capabilities, heater bake out, integrated heat sinks,
on-board fuses, RoHS compliance and serial communications.
Watlow DIN-A-MITE® and E-SAFE II power switching devices provide convenient DIN-rail mount packages and are a good replacement for mercury displacement relays.
Additionally the EZ-ZONE ST offers an integrated temperature and process controller with optional over- and under-temperature limit and safety shutdown contactor.
