Standard SSR's
SSR Series Single phase, zero cross SSR Power Controller
Chromalox SSR power controllers deliver high precision power modulation and smooth power output to the heating load, ensuring process stability. Chromalox delivers, from stock, an entire range of industrial SSR power control units to handle your toughest heating applications. These units are easy-to-install, are maintenance-free and employ the latest SSR power control technology and features.
The Chromalox SSR family line of solid state relays are an ideal low cost power control solution for furnace/oven, heat treating, plastics, food, semiconductor, lighting, and drying applications just to name a few. The SSR line of power controllers are a complete package. They feature a rugged design, touch safe exterior, back-to-back SCR design, ambient ratings of 40˚C, and are DIN rail mount.
The benefits from the Chromalox SSR line are quick and low cost installation, reduced panel space, increased heater life due to fast cycling, and easy replacements for mechanical contactors.
SSR1, SSR2 & SSR3 Series:
SSR1 Single phase, zero cross SSR power controllers
SSR2 3-phase, 2 leg, zero cross SSR power controllers
SSR3 3-phase, zero cross SSR power controllers
These units are rated for 10, 15, 25, 35, 40, 50, 70 and 75 amps with operational voltages up to 600 VAC. The series is zero-fired single phase, three-phase two leg and three-phase three leg control. The control signal can be 4.5 - 32 VDC, or 24 - 265 VAC / 24 - 190 VDC.
SSR1P Single phase, phase angle SSR Power Controller
These units are rated for 15, 25, 35, 40, 50 and 70 amps with operational voltages up to 600 VAC. The series is phase-angle fired single-phase and three-phase three leg design. The control signal can be 4 - 20 mA or 0 - 20 mA.
