- 0.5 to 10hp : 20% Duty -

M3675T Braking Transistors are ideal for drives with no internal braking transistor or 7th IGBT.

Bonitron M3675T units 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 M3675T works with Variable Frequency Drives (VFD) to monitor the DC bus. If overvoltage occurs, the M3675T shunts the excess energy through a braking resistor to prevent overvoltage faults.

Standard and custom braking resistors are also available from Bonitron. For more information see the M3575R series.

Note: Tables are a general guide. DC bus connections needed to connect a Bonitron transistor. Confirm resistor ohm rating is higher than drive's min ohm if connecting directly to drive brake.
