Active PFC Circuitry

In the era of rapid industrial automation and smart manufacturing, stable and efficient power supply equipment serves as the cornerstone for ensuring reliable system operation. Mibbo’s MHR Series Ultra-Wide Voltage Input DIN Rail Power Supply, with its exceptional adaptability, high reliability, and intelligent protection features, has become a benchmark product in the industrial power supply domain. Designed to thrive in harsh industrial environments and complex power demands, the MHR Series delivers sustained power support through three core advantages: wide input range, high isolation, and robust protection. Product Features Ultra-Wide Input Voltage Range Full series supports 180–550 VAC input (compatible with 254–780 VDC), adapting to global grid fluctuations. Ideal for voltage-unstable industrial scenarios, eliminating the need for additional voltage stabilization devices. Front-view diagram of full series (dimensions labeled). High Efficiency and Energy Savings Efficiency up to 93% (MHR480 model), integrated with active PFC circuitry to minimize energy loss. Natural convection cooling design requires no external散热装置, reducing maintenance costs. Multi-Layer Protection for Safety Integrated short-circuit, overload, overvoltage, and overtemperature protections with auto-recovery functionality. Overload mode automatically switches to constant current output to prevent equipment damage. Overtemperature protection triggers at 95±5°C (MHR480), ensuring stable operation in high-temperature environments. Flexible Compatibility and High Reliability Adjustable output voltage (e.g., ±20% for 24V models) to meet diverse load requirements. Compliant with EN 62368-1, GB4943.1 safety certifications. Isolation withstand voltage reaches 4.7 kV (MHR060), guaranteeing system safety. Compact Design and Easy Installation Supports TS-35/7.5 or TS-35/15 standard DIN rail mounting. Slim profile (32mm thickness for MHR060) optimizes space utilization. Operating temperature range spans -30°C to +85°C, suitable for extreme environments. ApplicationsThe MHR Series is engineered for industrial scenarios, including: Industrial Control Systems: Power for PLCs, servo drives, and other critical devices. Factory Automation: Stable supply for robotics, sensors, and inspection instruments. Semiconductor Manufacturing: High-precision equipment power in cleanroom environments. Electromechanical Equipment: Support for CNC machines, packaging machinery, and high-power loads. Renewable Energy: Integration with PV inverters and energy storage systems.
