Available. The Mitsubishi MR-J2S-20A is a servo amplifier from the MELSERVO-J2 Super series, designed to provide efficient control for servo motors in various industrial applications. It delivers a continuous output power of 200 W (0.2 kW) and operates with both single-phase 230 VAC and three-phase 200–230 VAC power supplies at 50/60 Hz. The amplifier supports pulse train position command inputs, making it compatible with a range of servo motors, including the HC-KFS23 and HC-MFS23 series. Key features include a built-in dynamic brake, a maximum input pulse frequency of 500 kpps (differential receiver) or 200 kpps (open collector), and a resolution of 131,072 pulses per revolution for precise positioning. The MR-J2S-20A is housed in a self-cooled, open structure (IP00) and operates within an ambient temperature range of 0°C to 55°C. Its compact dimensions (40 mm × 130 mm × 120 mm) and lightweight design (approximately 0.7 kg) make it suitable for integration into various industrial systems. This servo amplifier is ideal for applications requiring precise motion control and is particularly useful for replacing legacy units in existing systems.
