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 Silicon 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 Electromechanical Relays.
