Additional Information
- Functionality: The HD22005-3A features a 3-phase passive PFC circuit for input rectification and filtering, ensuring a power factor >0.94 and compliance with EMI/EMC standards (GB/T 17794.2.2-2003, DL/T781-2001). A DC/DC converter with PWM control delivers stable DC output via high-frequency transformation, rectification, and filtering. The module includes over/under-voltage protection, output over-voltage protection, short-circuit current limiting (40% of rated output), phase failure protection (derates to 2.5A at 260V), and over-temperature protection. It has a front-panel LED display for voltage and current, with fault codes and an A/V button to switch modes. RS485 enables real-time monitoring.
