The M3452 series are heavy-duty braking transistors designed to prevent overvoltage faults in AC drives by shunting excess DC bus energy through an external braking resistor. The M3452-U800YK9-R7E variant supports 800 A peak braking current and 400 A RMS current for 690 VAC drives with a 1090 VDC bus setpoint, operates with a 24 VDC control voltage (R7E option), and has dimensions of 20.00" x 9.05" x 10.25". It is UL and CUL listed, features EtherNet/IP and PROFIBUS DP networking options, and supports master/slave configuration. All units above 200 A include master/slave capability and are rated for a peak on-time of 60 seconds with continuous operation at the RMS rating.
Bonitron Braking Transistors are used with AC drives to allow full power braking and eliminate overvoltage faults. This permits controlled braking and dramatically shortens motor stopping time. The M3452 works with Variable Speed Drives (VSDs) to monitor the DC bus. If overvoltage occurs, the M3452 shunts the excess energy through a braking resistor to prevent overvoltage faults.
