Product Overview
The TH230D10ZZ-3G is an industrial-grade intelligent high-frequency switching power supply module engineered by Shijiazhuang Tonghe Electronics for global power systems. Adopting resonant voltage-type dual-loop control technology, it delivers a rated output of 230VDC/10A (3KW) with outstanding and stable operation.
Key Features
- High efficiency ≥95% with three-phase passive PFC circuit
- Power factor ≥0.93 for excellent energy optimization
- Wide input voltage range: 323~456VAC
- Adjustable output voltage: 190~300VDC
- ±0.5% voltage regulation accuracy and ±1% current regulation accuracy
- ≤0.2% ripple coefficient for high-purity DC power
System Integration & Protection
Modular design supports N+1 hot backup and seamless capacity expansion, enabling parallel operation with current sharing imbalance ≤±3%. Equipped with standard RS485 communication interface compatible with Modbus and TonHe dual protocols, enabling "four-remote capabilities" (telemetry, remote signaling, remote control, remote adjustment) for seamless automation integration.
Comprehensive multi-layer protection includes overvoltage protection (320±5VDC), short-circuit protection, overtemperature protection (automatic shutdown at 85℃ and restart at 80℃), and overcurrent protection. LED digital display with key operation supports three working modes (independent, manual, automatic), and hot-swappable design ensures efficient maintenance.
Design & Environmental Specifications
Natural cooling design with compact structure weighing only 9kg. Requires only good surrounding ventilation for stable operation. Excellent environmental adaptability operates reliably in indoor environments with temperature range of -10℃~+40℃, relative humidity ≤90% at 25℃, and altitude ≤2000m.
Applications
Widely used in various global scenarios including substations, power plants, and power control equipment. Provides highly reliable, efficient, and easy-to-integrate DC power supply solutions for power systems, ensuring continuous and stable system operation.

| Load Rating |
Continuous operation at 100% rated output current (Class I) |
| Automatic Current Limiting |
When output current exceeds the set limit, the module operates in constant current mode and the output current will not increase |
| Output Overvoltage Protection |
The module automatically stops output when voltage exceeds 160±3VDC to prevent equipment damage |
| Output Short-Circuit Protection |
The module self-protects in case of short circuit to prevent damage and automatically recovers after fault removal |
Note: Voltage regulation accuracy does not include the effect of the built-in isolation diode.
