M3452-C1600T10-R7

The Bonitron M3452-C1600T10-R7 is a high-current dynamic braking transistor designed for 575–600 VAC variable frequency drive systems. Built on the 1600 A T10 platform, this unit monitors the VFD DC bus and routes regenerative energy through an external braking resistor when bus voltage rises during deceleration or overhauling operation. This helps prevent DC bus overvoltage faults while allowing faster, more controlled motor stopping. The M3452-C1600T10-R7 uses 575–600 VAC control power and operates with a 940 VDC braking trigger level. Its standard R7 control board supports discrete hardwired control along with master/slave capability, making this configuration well suited for large industrial drive systems that need dependable high-power braking without the additional extended I/O of the R7E option.
