Mitsubishi MR-J4W3-444B AC Servo Drive 400W 200-240V

MR-J4W3-444B Servo Drive by Mitsubishi 200-240V

Product Introduction

The MR-J4W3-444B belongs to Mitsubishi’s MELSERVO MR-J4 series. This AC servo drive operates efficiently with a supply voltage of 200 to 240 Vac. It accepts both single-phase and three-phase input configurations. Therefore, you gain flexibility for different shop floor power setups.

Additionally, this drive provides a rated active power of 0.4 kW (400W). Its rated current is 2.8A, while the input current consumption reaches 7.8A. Such specifications make the MR-J4W3-444B suitable for many servo motor applications. The drive also carries an IP20 protection rating. As a result, it handles indoor environments with basic dust protection.

Technical Specifications

The MR-J4W3-444B operates within a temperature range of 0°C to +55°C. For storage, it withstands –20°C to +65°C. This wide range ensures reliable performance under varied conditions.

Moreover, the drive weighs only 2.27 kg (5.00 lbs). Its compact design simplifies cabinet installation. The unit works seamlessly with compatible Mitsubishi servo motors. You do not need complex adapters or additional interfaces.

Here are key electrical parameters:

• Supply voltage: 200 to 240 Vac (single-phase or three-phase)

• Rated active power: 0.4 kW (400W)

• Rated current: 2.8A

• Input current consumption: 7.8A

• Protection degree: IP20

Mechanical and Environmental Parameters

The MR-J4W3-444B handles normal operating temperatures from 0°C up to +55°C. During storage, the acceptable range extends from -20°C to +65°C. This durability makes it a robust choice for workshop environments.

Furthermore, its IP20 rating protects against solid objects larger than 12mm. However, you should keep it away from water or dust-heavy areas. The unit’s lightweight design (2.27kg) allows easy mounting inside standard control cabinets.

Installation Guidance

First, ensure the main power supply matches the required 200-240 Vac range. Next, confirm whether you will use single-phase or three-phase input. Then, mount the MR-J4W3-444B vertically on a flat, non-flammable surface.

For instance, leave enough space around the drive for proper airflow. The ambient temperature must stay below +55°C during operation. Additionally, use shielded cables for motor and encoder connections. This practice reduces electrical noise and improves system stability.

Finally, connect a compatible servo motor as per Mitsubishi’s wiring diagram. Always power off the system before making any connections. Following these steps will help you achieve trouble-free operation.
