Two Phase Thyristor Controllers

Download the PMA BrochureWest Control Solutions presents a range of thyristor power controllers which have been designed to switch 2 legs of 3 phase loads. These thyristor units are ideal for 3 phase configuration, resistive load, without neutral connection.

Relay S – 2PH = 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 - 2 PH = Fully adjustable burst firing (3 to 255 cycles), front panel display & keypad plus RS485 comms as standard

front panel display & RS485 comms

PMA3000 - 2PH = More complex load requirements such as feedback and current limit

Relay S - 2PH Thyristor Power Controller - up to 700A
