The M3452-H300K6 is a heavy-duty braking transistor module designed for AC drives to prevent overvoltage faults by shunting excess energy to a braking resistor. It operates with 460-480VAC drives and has a DC bus setpoint of 750 VDC. The unit has a peak braking current of 300 A and a braking resistor of 2.50 Ω. It is rated for a minimum of 200 A and includes Master/Slave capability. The module measures 20.00" x 7.12" x 10.50" and is UL and CUL listed. Control voltage is 460 VAC, and it supports remote monitoring and networking options including EtherNet/IP and PROFIBUS DP. Maximum 'on-time' at peak rating is 60 seconds, with continuous operation allowed at RMS current levels.
Heavy Duty Braking Transistor Modules. Overvoltage Solutions for AC Drives. Braking Transistor and Braking Resistor modules are used with AC drives to eliminate overvoltage faults. The use of these modules permits controlled braking of the AC drive and dramatically shortens the time required for motor stopping as opposed to coasting. Bonitron M3452 Heavy Duty Braking transistors are used in applications that have continuous or high duty cycle requirements. The modules are used with drives that have inadequate or no internal braking transistor. They work with any AC drive system with DC bus field terminals. The Bonitron M3452 Braking Transistor modules monitor the drive DC bus levels and control an IGBT power switch which is connected to a resistive load for dissipating the regenerated energy. Standard modules are available rated up to 1200 Amps DC and Braking Duty Cycles up to 100%.
