M3452-H1600T10-R7

The Bonitron M3452-H1600T10-R7 is a high-power dynamic braking transistor designed for 460–480 VAC variable frequency drive systems that experience regenerative energy during rapid stopping or overhauling operation. Using 460–480 VAC control power, this T10 configuration monitors the drive DC bus and switches excess energy to an external braking resistor when voltage reaches the 750 VDC braking threshold. Rated for 1600 A peak and 1200 A RMS braking current, the unit supports a minimum braking resistance of 0.47 ohms for demanding high-horsepower applications. The standard R7 control option provides discrete hardwired control and monitoring, making this model a practical solution for large industrial VFD systems requiring reliable braking performance and protection against DC bus overvoltage faults.
