M3775R Resistive Load Banks 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, a Bonitron Transistor or the drive’s internal brake, shunts excess energy through a Bonitron M3775R Resistive Load Bank to prevent overvoltage faults.
