Eurotherm TE300 SCR Power Controller Inquiry Item

Details

This Eurotherm TE300 is a thyristor (SCR) power controller for resistance heating loads. It supports phase angle control and burst firing control modes, receiving 4~20mA or 0~10V control signal from PID temperature controller to adjust output power continuously. It can adapt to single-phase or three-phase load wiring modes, including star, delta closed/ open winding connections. Built-in heater break detection, current monitoring and overcurrent protection. The TE300 series has been discontinued, widely used in heat treatment furnace, packaging heat sealing, plastic extrusion, infrared heating industry, it is a common maintenance spare for old thermal process control cabinets.
