    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.

    M3452-U1600HM14-R7E

    The Bonitron M3452-U1600HM14-R7E is a high-current dynamic braking transistor designed for large 460 VAC variable frequency drive systems that generate significant regenerative energy. Rated for 1600 A peak and 1200 A RMS braking current, this M14 configuration monitors the drive DC bus and switches excess energy to an external braking resistor when voltage rises above the braking threshold. By controlling regenerative energy during rapid deceleration or overhauling loads, the unit helps reduce DC bus overvoltage trips and supports consistent motor stopping performance. The M3452-U1600HM14-R7E uses 120 VAC control power, a 750 VDC braking setpoint, and a 0.47-ohm minimum braking resistance. Its R7E control configuration adds enhanced monitoring and diagnostic capability for demanding industrial VFD applications.

    M3452-U1600HT10-R7

    $20,449

    M3452-U1600HT10-R7

    The Bonitron M3452-U1600HT10-R7 is a 1600 A heavy-duty dynamic braking transistor built for high-power 460–480 VAC variable frequency drive systems. Designed to monitor the VFD DC bus, the M3452 activates when regenerative energy causes bus voltage to rise, routing that excess energy through an external braking resistor to help prevent overvoltage faults and shorten motor stopping times. This model supports up to 1600 A peak and 1200 A RMS braking current with a 750 VDC braking setpoint and 0.47-ohm minimum resistance. The R7 control configuration provides hardwired enable, fault reset, master/slave control, and system status outputs, making this unit well suited for large industrial drive applications requiring high-current regenerative braking and straightforward external control.

    M3452-U1600HT10-R7E

    $20,766

    M3452-U1600HT10-R7E

    The Bonitron M3452-U1600HT10-R7E is a heavy-duty braking transistor designed for high-horsepower 460–480 VAC variable frequency drive applications. Rated for up to 1600 A peak braking current, this unit monitors the VFD DC bus and directs excess regenerative energy to an external braking resistor when bus voltage rises. This controlled dissipation helps prevent DC bus overvoltage faults while providing faster, more predictable motor stopping. The M3452-U1600HT10-R7E uses 120 VAC control power and features the R7E control option for enhanced system status, diagnostics, and control capabilities. With a 750 VDC braking setpoint and 0.47-ohm minimum braking resistance, this configuration is suited for demanding regenerative loads requiring high-current dynamic braking and reliable overvoltage management.
