The TH110D10ZZ-3 is an industrial-grade intelligent high-frequency switching power supply module engineered for global power systems. Adopting advanced resonant voltage-type dual-loop control technology, it delivers a rated output of 110VDC/10A (1.5KW) with outstanding and stable performance.

• Efficiency range of 90%~96% with three-phase passive PFC circuit (power factor ≥0.95)
• Wide input voltage range: 353~478VAC with adjustable output: 88~150VDC
• ±0.5% voltage regulation accuracy and ±1% current regulation accuracy
• Withstands short-term inrush current above 2Ie (300ms) for complex working conditions
• Modular design supports N+1 hot backup and seamless capacity expansion
• Up to 20 units operating in parallel with current sharing imbalance ≤±3%
• Standard RS485 communication interface compatible with Modbus and TonHe protocols
• Comprehensive protection: overvoltage, short-circuit, overtemperature, and overcurrent
• LED digital display with manual voltage adjustment and multiple operating modes
• Hot-swapping capability for safe and efficient maintenance

• 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
• Output Overvoltage Protection: Automatically stops output when voltage exceeds 160±3VDC
• Output Short-Circuit Protection: Self-protects in case of short circuit and automatically recovers after fault removal

Note: Voltage regulation accuracy does not include the effect of the built-in isolation diode.

We are a high-tech enterprise integrating manufacturing, sales, system solutions, and after-sales service. With over 290 successful projects for 220 kV to 500 kV substations and battery systems above 1000 Ah, Tonhe has become a leading DC power system supplier in China, holding over 40% market share and producing 1 million modules annually.

Our 8 advanced production lines, equipped with imported machinery, achieve 80% automation and up to 99% first-pass yield. All power modules undergo double-sided potting, conformal coating, and rigorous functional, environmental, and aging tests--ensuring reliable 24/7 performance in critical power infrastructures.

We provide a full range of power conversion modules, system-level low-voltage DC distribution cabinets for DC loads, data center power systems, as well as customized hardware and software power solutions.
