Product Description
The Mitsubishi MR-J2S-40CP AC Servo Drive delivers high performance and efficiency for diverse industrial uses. Its rapid, reliable operation is supported by a two-minute discharge time and a 0.9 kVA power supply suitable for servo motor control. The servo amplifier generates 35W of heat at rated torque, dropping to 15W when off, requiring a 0.7 sq meter cooling area. The main circuit (L1, L2, L3) needs 30A, while the control circuit (L11, L21) requires 70-100A, attenuating to ~0A in 0.5-1ms. With an 85% inverted efficiency, it optimizes power usage. It has an 11-joule capacitor charging capacity and is easily installed with M4 screws. Compact at 16.8cm x 13.5cm x 7cm and weighing 0.75kg (1.1kg packaged), it's a portable servo motor control solution.
