Mitsubishi's MRH22KBN is an AC servo amplifier tailored for high-performance applications within the MELSERVO MR-H series. It supports a 3-phase input voltage range of 200 to 220 volts AC for 50 Hz and 200 to 230 volts AC for 60 Hz. The amplifier detects absolute position when connected to an encoder and battery. With a rated output of 22 KW, the MRH22KBN can handle significant loads.
This unit operates efficiently in environments with humidity levels reaching up to 90% (non-condensing) and is functional over a temperature range of 0°C to 55°C, ensuring reliable performance in various conditions. The design is classified as IP00, providing an open frame that is not enclosed.
This model's power supply capacity is rated at 33 kVA, and a dynamic brake is offered as an optional feature. It employs a current control system using sine-wave PWM for precise motor control. The device can tolerate voltage fluctuations of 170 to 242 volts AC at 50 Hz and 170 to 253 volts AC at 60 Hz. Additionally, frequency fluctuations of ±5% are permissible under normal operating conditions.
Safety features such as protections against overcurrent, overvoltage, and thermal overload contribute to the amplifier’s durability. Furthermore, it has provisions to detect encoder issues. The MRH22KBN amplifier can achieve a speed frequency response of at least 250 Hz, ensuring it can meet dynamic application demands.
