MR-H350BN

The MR-H350BN model is an SSC-NET-compatible AC servo amplifier produced by Mitsubishi under the MELSERVO MR-H line. It is engineered to deliver a rated output of 3.5 kW, providing efficient power management for industrial applications. This unit supports multiple servo motors, including the HC-SF301, HC-SF352-353, HC-RF203, and HC-UF202, making it versatile for different setups.

Incorporating built-in dynamic braking enhances its performance during sudden stops or changing motion speeds. This amplifier employs a sine-wave PWM control approach and a current control system to improve overall functionality and stability during operation. The power supply requires a 3-phase input voltage ranging from 200 to 230 VAC at a frequency of 50/60 Hz, with permissible fluctuations extending from 170 to 253 VAC. It can also accommodate frequency fluctuations of ±5%.

The MR-H350BN is equipped with comprehensive protective functions, including safeguards against overcurrent, overvoltage, overload, encoder faults, and undervoltage. These features ensure the unit operates safely and reliably in various operating conditions. It offers impressive speed frequency response capability reaching 250 Hz or more, crucial for applications demanding rapid motion changes.

For environmental considerations, this servo amplifier operates effectively in temperatures ranging from 0°C to +55°C while maintaining a non-condensing humidity level of up to 90% RH. The open structure of the amplifier is rated at IP00 and indicates that it is suitable for indoor installations free from direct exposure to moisture or particulate contamination. The device also supports an encoder resolution of 16,384 pulses/revolution, specifically designed for use with the HC-SF series, enabling precise control of motion with high accuracy.
