EMERSON HD22010-3
Product Introduction
The EMERSON is a high-frequency switching DC charging module, widely used as a core component in 35kV to 330kV substation DC panel systems. It provides stable and reliable DC power for critical applications such as relay protection, circuit breaker operation, and emergency lighting.
Utilizing advanced phase-shifted resonant soft-switching technology, the achieves high efficiency (≥92%) and excellent electromagnetic compatibility. It features a built-in CPU for decentralized control and communicates via an RS485 interface, supporting remote telemetry and control (四遥功能). The module’s innovative self-cooling/fan-cooling hybrid design ensures quiet operation under light loads and effective heat dissipation under full load. Its hot-swappable capability allows for online maintenance without system downtime.

Quality Control Process (Engineer’s Perspective)
- Incoming Verification: Verify part number . Inspect the front panel LED display, fan grill, and rear connectors for physical damage.
- Visual Inspection: Check the aluminum die-cast housing for cracks or deformation. Ensure the cooling fan spins freely and the air intake/exhaust is not obstructed.
- Live Functional Test: Install in a compatible DC panel chassis. Apply 3-phase AC power and verify the module powers up, the output voltage stabilizes, and the LED display shows normal parameters.
- Load & Communication Test: Verify RS485 communication with the system monitor. Test output current capability under load and verify intelligent fan speed adjustment based on temperature and load.
- Final QC & Packaging: Seal in an anti-static bag. Apply a QC Passed label with the date.

Replacement Pitfall Guide
❗ Legacy Model Status: The is a legacy model and has been largely replaced by the newer ER22010/T series. The ER series offers higher power density, integrated CAN bus communication (eliminating external equalizing lines), and simplified installation. Verify if an upgrade is possible before replacing with the same legacy model.
❗ RS485 vs. CAN Bus: The uses RS485 for communication and requires a separate equalizing bus cable for parallel operation. Do not confuse this with the CAN bus-based ER series. Incorrect wiring of the equalizing bus can cause system instability.
❗ Hot-Swap Safety: While the module supports hot-swapping, always follow site safety protocols when handling live DC equipment. Ensure the system monitor is configured to properly manage the module during insertion/removal.
❗ Phase Loss Protection: The module features a unique phase-loss protection design. If one AC phase is lost, the module will automatically limit its output to half-load (5A at 260V) rather than shutting down. Verify your 3-phase input is balanced.
❗ Fault Code Diagnostics: The front panel LED displays fault codes for troubleshooting. Common codes include:
- E31: Output Undervoltage
- E32: Module Over-Temperature
- E33: AC Input Over/Undervoltage
- E36: Output Overvoltage
If a fault code persists after a restart, the module likely requires professional repair.
❗ Environmental Limits: The operating temperature range is -10°C to +40°C. Ensure adequate ventilation in the DC panel cabinet to prevent over-temperature protection shutdowns.
Compatibility Matrix & Benchmarks
- → ER22010/T : Recommended Upgrade — Newer generation with CAN bus, higher power density, and easier installation.
- → HD22020-3 : Alternative — Use HD22020-3 if a 20A output rating is required (same form factor family).
- → HD11020-3 : Alternative — Use HD11020-3 if your system requires a 110V DC / 20A output configuration.
- → PSM-E11 / PSM-E20 Monitor : Complementary — Requires a compatible system monitor for centralized control and alarm management.
Benchmarks:
- Output Precision: Voltage/Current regulation ≤ ±0.5%
- Ripple Coefficient: ≤ 0.1%
- Current Sharing: ≤ ±5% imbalance (typical 3%) at 50-100% load
- Acoustic Noise: < 55 dB
