EMERSON HD22005‑3

Product Name: High‑Efficiency Rectifier Charging Module

Product Brief Introduction: Industrial high‑frequency switch rectifier module, used for DC screen power supply system, converts AC input into stable 220 VDC output for battery charging and DC load power supply.

Technical Specifications: Three‑phase AC input 323‑475 VAC; Rated DC output 220 VDC; Rated output current 5 A; Rated output power 1100 W; RS485 communication interface; Active current sharing function for parallel multi‑module operation; Module efficiency ≥90 %.

Category:
Description

Functional Features: Input over‑voltage, input under‑voltage, output over‑voltage, output under‑voltage, short‑circuit and over‑temperature multi‑protection; Temperature‑controlled fan stepless speed regulation; Digital fault code display; Remote monitoring via RS485 bus; Multi‑module parallel current sharing operation support.

Application Scenarios: Substation DC power screen; Power station battery charging system; Industrial uninterrupted DC power supply; Telecommunication base station power system; Industrial control cabinet DC backup power system.

Performance Parameters: Wide three‑phase AC input adaptability; Active current sharing accuracy; Digital fault code local display; Remote parameter setting and status reading; Automatic derating under over‑temperature condition.

Material Composition: Metal aluminum alloy housing; High‑frequency power switching devices; Industrial digital control circuit board; Temperature‑controlled cooling fan; Insulated integrated power socket terminal.

Structural Characteristics: Compact 19‑inch cabinet plug‑in structure; Front‑panel digital display and indicator lights; Rear integrated multi‑pin socket for power, communication and current‑sharing signal connection; Internal heat‑dissipation air duct design; Built‑in isolation protection circuit.

Working Principle: Three‑phase alternating current passes input filtering and rectification, then high‑frequency DC‑DC power conversion, outputs stable 220 VDC. Built‑in digital control unit collects module voltage, current and temperature data, completes protection logic, fan speed adjustment, current‑sharing control and RS485 communication interaction.

Installation Requirements: Install in standard DC screen cabinet; Ensure front‑to‑back ventilation air‑path unobstructed; Connect protective ground terminal reliably; Complete current‑sharing signal wiring when multiple modules work in parallel; Power‑on wiring shall strictly follow pin definition of integrated socket.

Usage Notes: Prohibit operating without protective ground connection; Keep ventilation channel free of blockage; Do not operate beyond rated output current; Read fault codes for troubleshooting upon abnormality; Do not disassemble module housing on site; Avoid conductive dust accumulation inside cabinet.
