TH230D10NZ-6 Rectifier Module 220V/10A Charging Module for DC Power System

The TH230D10NZ-6 is a high-frequency switching rectifier (charging) module specially developed for 220V DC power systems. It converts three-phase AC input into stable, regulated DC power to charge battery banks and to supply critical loads such as relay protection devices, circuit-breaker operating mechanisms, monitoring and control systems. Built on high-frequency soft-switching technology with intelligent forced-air cooling, the module delivers high efficiency, compact size and long-term reliability. Featuring RS485 communication with "four-remote" (remote measure, signal, control, regulate) capability, modular hot-swap design and N+1 redundancy support, it is the ideal choice for building, expanding or maintaining DC power systems in substations, power plants, switchgear rooms, rail transit and telecom facilities.

Product Parameters

Product Advantages
- High efficiency, low running cost — ≥95% conversion efficiency reduces energy consumption and heat dissipation in long-term operation.
- Intelligent thermal management — built-in temperature-controlled fan auto-adjusts speed, ensuring stable performance and extended service life.
- Comprehensive protection — over/under-voltage input, over-voltage, over-current, short-circuit and over-temperature protection keep both the module and the DC system safe.
- Smart remote monitoring — RS485/Modbus interface enables "four-remote" control for seamless integration into automation and SCADA systems.
- Hot-swap, N+1 redundancy — a faulty module can be replaced online without interrupting system power, maximizing system availability.
- Digital load sharing — <±3% current-sharing deviation supports parallel connection of 20+ modules for easy capacity expansion.
- Built-in output isolation diode — no external diode required, simplifying system integration.

FAQ
1. Can multiple modules be connected in parallel for expansion?
Yes. The module adopts digital load sharing with a current-sharing deviation of less than ±3%, supporting more than 20 modules in parallel. N+1 redundant configuration is recommended to ensure continuous power supply even if one module fails.
2. What happens if a module fails? Does it affect the whole system?
No. The module supports live hot-swapping. A faulty module can be replaced online while the DC system continues normal operation, significantly reducing maintenance downtime.
3. What are the input power requirements?
The module accepts three-phase AC 380V ±15% (4-wire), with strong tolerance to grid fluctuation. If only single-phase power is available on site, please contact us to select the appropriate input configuration.
4. How can I monitor and control the module remotely?
It is equipped with a standard RS485 communication interface supporting Modbus protocol, enabling remote measuring, signaling, control and regulation (four-remote) through a compatible monitoring system or SCADA.
5. What about warranty and technical support?
We provide professional technical consultation, selection guidance and installation/commissioning advice, plus comprehensive after-sales service and warranty. Please contact us for detailed warranty terms and documentation.
