M3452-U1600HM14-R7E
$17,568
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.
