The M3575T series consists of standard duty braking transistor modules designed to dissipate regenerated energy from AC drives, preventing overvoltage faults and reducing motor stop times. These modules are wall or cabinet mountable, feature enclosed chassis packaging, and connect via four terminals: drive DC bus, resistors, and status. Operating with 230 or 460 VAC line voltages, they handle currents from 5 to 600 amps with a maximum 20% braking duty cycle and 60-second maximum on-time. Turn-on and turn-off thresholds are set at 375/750 VDC and 365/725 VDC for 230V and 460V systems respectively, with no field adjustments required. UL or CUL certification applies to models up to 75 amps. Fault output releases upon overtemperature, transistor failure, or open load conditions.
Standard Duty Braking Transistor Modules. Overvoltage Solutions for AC Drives. Dynamic Braking Transistor and Dynamic Braking Resistor Modules are used with AC drives to dissipate regenerated energy and eliminate overvoltage faults. These modules permit controlled braking of the AC drive, dramatically shorten the time required for a motor to stop as opposed to coasting. Bonitron M3575T Standard Duty Braking Transistors can be used to increase productive throughput by decreasing stopping time and are designed to be used with all drives with DC bus field terminals. The M3575T Braking Transistor Modules monitor the drive DC bus levels and control power to a resistive load dissipating regenerated energy. Standard modules are available rated up to 600 Amps DC with Braking Duty Cycles up to 20%.
