M3775R Braking Resistors are used with Bonitron Braking Transistors to allow full power braking and eliminate overvoltage faults. This permits controlled braking and dramatically shortens motor stopping, time. If overvoltage occurs, Bonitron Transistors or the drive’s internal brake, shunts excess energy through a Bonitron M3775R Braking Resistor to prevent overvoltage faults.
