Three Phase Thyristor Power Controllers

Enquiry widget >West Control Solutions presents a range of thyristor power controllers which have been designed to switch 3 legs of 3 phase loads. These thyristor units are ideal for 3 phase configuration with neutral connection, normal (Relay S or Relay M) or variable resistive loads and transformer load types (PM3000-3PH).

Relay S- 3PH = 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 - 3PH = Time proportioned burst firing with a DC linear input (fully adjustable burst firing (3 to 255 cycles)), front panel display & keypad plus RS485 comms as standard

PMA3000 - 3PH = More complex load requirements that may need phase angle firing, delayed triggering, or features such as feedback, current limit etc.
