M3452-U1600HM14-R7

The Bonitron M3452-U1600HM14-R7 is a heavy-duty dynamic braking transistor designed for high-horsepower variable frequency drive systems that require dependable control of regenerative energy. This 1600 A M14 configuration monitors the VFD DC bus and switches excess energy to an external braking resistor, helping prevent DC bus overvoltage faults during deceleration, stopping, or overhauling operation. Rated for 1600 A peak and 1200 A RMS braking current, the unit supports a minimum braking resistance of 0.47 ohms and uses 120 VAC control power. The standard R7 control board provides a straightforward control platform for demanding industrial braking applications, while the open-chassis M14 construction is designed to accommodate the high-current requirements of large drive systems.
