Matching YZR series resistors in R series cranes is mainly used as a universal resistor for S3, S4, and S5 working systems of YZR series motors in cranes and similar lifting equipment. It is suitable for circuits with AC 50HZ and voltage up to 660V and cooperates with controllers (screens) to control the starting, speed regulation, and braking of electric motors.
