The M3452 series is a heavy-duty braking transistor designed to prevent overvoltage faults in AC drives by shunting excess DC bus energy through a braking resistor, enabling controlled motor deceleration. The M3452-E1600M14-R7 variant supports up to 1600A peak braking current at 380VAC drive input and 1090VDC bus voltage, with a minimum physical size of 28.00" x 13.90" x 14.60". The unit is UL and CUL listed, features R7 control option for 24VDC control voltage, and supports master/slave configuration. Parallel operation allows higher current ratings beyond single-unit capacity.
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.
