The MRH100A from Mitsubishi is a robust servo amplifier belonging to the MELSERVO MR-H series. It is engineered to handle a rated output power of 1 kW, making it suitable for various servo control applications. This amplifier accommodates input voltages between 200 and 230 VAC, facilitating flexibility in terms of power supply configurations. It supports 1-3 phase connections.

The MRH100A's rated current is capped at 5A. Control is managed via a sine-wave PWM methodology, which ensures effective motor performance. For added compatibility, the amplifier features a USB communication function compatible with MR Configurator2, easing the setup and configuration process.

Power supply requirements include a 24 V DC input, with a tolerance range of ± 10% and a minimum current requirement of 0.1 A. Cooling is achieved naturally, promoting efficient operation without additional active cooling elements. The protective class is classified as open (IP20), suitable for controlled environments.

The MRH100A operates effectively on a range of temperatures; specifically, it can function from 0°C up to 55°C while storing without damage at temperatures as low as -20°C and up to 65°C. Humidity levels during operation and storage should not exceed 90% RH, and the unit is built to endure vibrations, rated for 5.9 m/s² from 10 Hz to 55 Hz. The protective features incorporated in the MRH100A ensure reliability, including overcurrent shut-off, regenerative overvoltage shut-off, electronic thermal overload protection, and servo motor overheat protection.
