Description
Brake Resistor for MR-J3-10 to MR-J3-70 (MR-RB032 and MR-RB12)
The MR-RFH75-40 Brake Resistor is a specialized component designed to be used in conjunction with the MR-J3 series servo amplifiers, specifically the MR-J3-10 to MR-J3-70 models. It is compatible with both the MR-RB032 and MR-RB12 models of Mitsubishi servo amplifiers.
The function of this brake resistor is to dissipate the excess energy generated during deceleration or braking of the servo motor. When the motor is operating, it builds up kinetic energy. However, when the motor decelerates or comes to a stop, this energy needs to be dissipated to prevent any damage to the motor or the amplifier.
By connecting the MR-RFH75-40 Brake Resistor to the MR-J3 servo amplifier, it provides a safe and reliable method to handle this excess energy. The resistor absorbs the energy and converts it into heat, which is then dissipated into the surrounding environment.
The MR-RFH75-40 Brake Resistor has a rated power of 75W and a resistance value of 40 ohms. It is designed to withstand the high temperatures generated during operation and has a compact form factor, making it suitable for use in various industrial applications.
