West Control Solution Powerstack 3PH Thyristor Power Controller
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. West Control Solutions presents a range of thyristor power controllers which have been designed to switch 3 legs of 3 phase loads.
