Braking Transistor Products

Bonitron Braking Transistors are used with AC drives to allow full power braking and eliminate overvoltage faults. This permits controlled braking and dramatically shortens motor stopping time. Bonitron transistors monitor the DC bus, and if overvoltage occurs, the transistor shunts the excess energy through a resistor to prevent overvoltage faults.

The M3675T shown below is rated for lower-current applications in 110–480VAC configurations. For the full range of sizes, see our complete line of Braking Transistors, or use our How to Size a Braking Transistor guide to find the right rating for your application.
