Electromagnetic brake motor
To release the electromagnetic brake and install the load, a DC power supply is needed to power the
electromagnetic brake. Use an extension cable for electromagnetic brake to connect a DC power supply of
24 VDC±10% to the motor.
Unit models come with an extension cable for electromagnetic brake.
