TH110D40NZ-6 110V DC Rectifier Module | 40A Industrial Power Supply

The TH110D40NZ-6 is a high-frequency switching DC rectifier module designed and manufactured by TONHE (Shijiazhuang Tonhe Electronics Technologies Co., Ltd.) for medium-to-large scale industrial DC power systems. It converts a three-phase 380VAC supply into a stable 110VDC / 40A output (4.4kW) with a wide adjustable range of 88–150VDC.

Built on active Power Factor Correction (PFC) and digital LLC resonant conversion technology, the module delivers ≥95% peak efficiency and ≥0.95 power factor in a compact fan-cooled housing (342×237×89 mm). A standard RS-485 interface with "Four-Remote" monitoring functions allows seamless integration into automation and SCADA systems, while N+1 hot-swap redundancy ensures uninterrupted operation in critical power infrastructures.

Typical applications: substations, power plants, factory automation, and data-center backup power systems, as well as upgrading existing 110V DC systems for higher capacity, efficiency, and remote management capability.

Product Advantages
- Higher Efficiency, Lower Operating Cost — ≥95% peak efficiency and ≥0.95 power factor reduce energy loss, heat generation, and long-term cooling and running costs.
- Proven Reliability & Full Protection — 40A continuous output with overvoltage, short-circuit foldback, and automatic current limiting; all modules undergo double-sided potting, conformal coating, and aging tests for 24/7 duty in critical power infrastructures.
- True N+1 Scalability — supports hot-swap parallel operation with ≤±3% current sharing, so you can scale capacity or perform maintenance without system downtime.
- Smart Remote Management — standard RS-485 with Four-Remote functions enables full remote monitoring, control, alarm, and adjustment through the DC power system controller.
- Compact & Easy to Integrate — 342×237×89mm fan-cooled design with plug-and-play rear connectors, ideal for rack-mount DC panels and existing-system upgrades.
- Factory-Direct Quality — 80% automated production with up to 99% first-pass yield, CE/ISO9001 certified, backed by a 12-month warranty and a proven global field track record.

FAQ
Q1: What AC input does the TH110D40NZ-6 require?
A: It requires a three-phase 380VAC supply (−15% ~ +20%, i.e., 323–456VAC) at 45–55Hz, designed for standard industrial three-phase mains.

Q2: Can multiple modules be paralleled, and can they be replaced without downtime?
A: Yes. The module supports N+1 hot-swap parallel operation with automatic current sharing (imbalance ≤±3%). A faulty module can be removed and replaced live without interrupting the DC bus.

Q3: What protections are built in?
A: Overvoltage protection (software-configurable alarm and output shutdown), short-circuit protection with self-protective foldback and automatic recovery, and automatic current limiting (settable 4–44A).

Q4: How is the module monitored and controlled remotely?
A: Via the standard RS-485 communication interface with Four-Remote functions (remote measurement, signaling, control, and adjustment), enabling full integration with the DC system controller or SCADA network.

Q5: What are the MOQ, warranty, and delivery terms?
A: The MOQ is 5 pcs at factory price with T/T payment, delivery in approximately 7 days, and a 12-month warranty. Sample orders are available (sample cost paid by the customer) for quality verification before bulk ordering.
