MR-J3-350A4

Within Mitsubishi's MELSERVO MR-J3 lineup, the MR-J3-350A4 servo drive is engineered for robust control and efficiency. This unit provides a substantial rated active power of 3.5 kilowatts, making it ideal for demanding applications. It operates on a 3-phase input and has a supply voltage rating that spans from 380 to 480 volts AC. Enabling advanced performance, the device utilizes a sine wave pulse width modulation (PWM) method alongside current control technology.

Additionally, the MR-J3-350A4 is equipped with a built-in dynamic brake, improving its braking capabilities. Cooling is accomplished through forced ventilation, allowing for consistent performance even under heavy loads. The inrush current is notable, reaching 66 amperes for the main power supply and 41 amperes for the control circuit.

The servo drive can efficiently manage a variety of inputs and outputs, featuring 11 digital inputs, 5 digital outputs, as well as 3 analog inputs and 2 analog outputs. It also includes an impressive capacitor charging capacity of 36 joules. For energy management, the unit has a built-in regenerative resistor rated at 100 watts.

Notably, it has an input current rating of 8.6 amperes, which ensures reliability in operation. The capacitor discharge is efficient, requiring approximately 10 minutes for complete discharge, reflecting its design focus on safety and performance. The MR-J3-350A4 demonstrates Mitsubishi's commitment to delivering high-quality automation solutions.
