MR-J2-70A

Mitsubishi Electric's MR-J2S-70A AC servo amplifier is an essential part of automated manufacturing systems. This amplifier is versatile since it may use a 3-phase power supply with AC voltage from 200 to 230 volts at 50/60 Hz frequency, making it ideal for use in PLC systems that need precise control over servo motor systems. This amplifier features a sine-wave PWM control system in conjunction with current control to not only guarantee accuracy but also show resilience against fluctuations in voltage and frequency, with a voltage range of 170 to 253 Volts AC for 3-phase and a frequency range of +/-5%. Along with other safeties against things like overcurrent, overspeed, overload, regenerative overvoltage, power failure, servo motor overheating, and excessive error, this device also has a dynamic brake. The servo amplifier does have a general-purpose interface. The MR-J2S-70A can function normally between temperatures of 0 and 55 degrees Celsius and at heights of up to 10 meters (32,800 feet). It works in tandem with servo motors such as the HC-KFS73, HD-MFS73, and HC-UFS72/73, and has a rated output of 750 Watts and a power supply capacity of 1.3 kVA. The amplifier achieves a good efficiency-to-heat-management trade-off by dissipating just 15 Watts of heat while the servo is not in use, compared to 50 Watts of under-rated torque. The MR-J2S-70A is a high-speed servo motor controller that plays a crucial role in industrial automation thanks to its accuracy, durability, and flexibility in the face of input pulse frequencies of up to 500 kbps for differential receivers and 200 kbps for open collectors.
