Thyristor Power Controller 8 - 1,500A, 220 - 1,000V (4 - 1,000kW)

TPS Thyristor Power Controller

The TPS is a fully digital Thyristor Power Controller. The TPS has a heavy duty one, two or three phase power unit for controlling the voltages applied to loads such as a variety of heating elements. The TPS allows continuous automatic temperature control while eliminating contactor switching and over/under heating. Standard features are phase control, zero crossing, PID input, local potentiometer control, and optional RS-485 communications.
