The M3452 series is a heavy-duty braking transistor designed to prevent overvoltage faults in AC drives by shunting excess DC bus energy through an external braking resistor, enabling controlled motor stopping. The M3452-U150YB7-A operates with 575-600VAC drives at a 940VDC setpoint, with a peak braking current of 150A and a resistance of 6.30 Ω. It is housed in a chassis measuring 17.75" x 7.00" x 8.10" and is UL and CUL listed. Control options include discrete hardwire inputs, and units in this series support master/slave functionality for coordinated operation. The M3452 series is rated for up to 1600A per unit and is applicable to industrial applications including conveyors, cranes, elevators, and hoists.
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 Frequency Drives (VFD) to monitor the DC bus. If overvoltage occurs, the M3452 shunts the excess energy through a braking resistor to prevent overvoltage faults. Standard and custom braking resistors are also available from Bonitron.
