West Control Solution Relay M-3PH Thyristor Power Controller is 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.
