Single Phase Thyristors Controllers

Download the PMA BrochureWest Control Solutions presents a range of thyristor power controllers designed to switch single phase loads. This type of thyristor units is ideal for normal or variable resistive loads as well as transformer and inductive load types

Relay S – 1PH = Simple on/off firing with a DC logic input, time proportioned burst firing with a DC linear input (basic firing selectable between 4,8 or 16 cycles).

Relay M – 1PH = Time proportioned burst firing with a DC linear input, front panel display & RS485 comms as standard

Relay CL = More complex load requirements inc. feedback and current limit
