SCR Electrical relays control voltage to fit your process needs. Phoenix Thermal Supply Power Relays include SSR power controls for a more versatile & precise temperature and power control for applications where you need tighter control. SCR’s have smooth switching like solid state relays but with a Input card allowing greater controllability. The input card allows control with Analog signal, AC, DC. The tight packaging allows for reduced control panel space and an easy installation.
With Silicone Controlled Rectifier switching your heater, the life is increased and temperature control can be really optimized. Due to the nicer switching of Solid State Relays, users can increase watt densities of their heaters and safely control them without the over-shooting of the mechanical switching. Single and Three Phase options. 3 phase 2-leg, 3 phase 3-leg, Phase Angle, Zero Cross Switching, Time Proportion, etc. Our sales engineers can help you select the correct SCR product for your process. Tighter control than Electro-mechanical Relays.
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.
We have several line of SCR power controls. These packages are Solid State Relays with and input card. We provide different configurations with and without heat sinks.
