Universal brake unit

A high-performance braking product developed and produced using advanced power technology and high-performance MCU controllers, combined with the new generation of IGBT power devices. Its product releases the electrical energy generated by the motor during the braking process through a power resistor (braking resistor) to generate sufficient braking torque and maintain the normal operation of equipment such as frequency converters.

Power range

220V、380V、660VAC

Input voltage

50Hz±5Hz
