AXPERT Opti-torque Electronic Soft Starter is a modern Digital Signal Processor based highly functional Soft Starter that is easy to use. Six thyristors are used in back to back connection. The control board uses 32-bit High-Performance Digital Signal Processor and generates the necessary gate pulses for Soft Starter operation. It accepts various inputs from different circuits and Digital Operation Panel (LCD Keypad Module) to generate the necessary control and gate signals.

Models:  50 to 1000HP
