A: Tonhe Electronics specializes in DC power rectifier systems, with a product portfolio covering 10 major categories: rectifier modules, DC rectifiers (in multiple voltage levels including 24V / 48V / 110V / 220V), HVDC (high-voltage DC) rectifiers for data centers, telecom rectifiers, industrial rectifiers, DC distribution panels (including controllers and monitoring equipment), and battery monitoring devices. Representative products include the TH230D40NZ-6 rectifier module (40A/9.2kW, efficiency ≥93%) and the liquid-cooled HVDC rectifier TH240H133LZ-A (240V/40kW, peak efficiency 98%).
A: The products are engineered to high reliability standards: MTBF (Mean Time Between Failures) exceeds 100,000 hours, with hot-swappable modules and N+1 redundancy configurations. Protection ratings reach IP30/40/54 (IP54 available for outdoor use), and the products comply with IEC, GB, and ISO standards. According to the official website, its products have proven their reliability in more than 290 high-voltage power projects.
A: The products serve four major sectors: ① Power industry — DC auxiliary power systems for power plants and substations; ② Data centers — HVDC high-voltage DC power supply systems; ③ Telecommunications — 48V DC power systems for telecom equipment rooms; ④ Industrial applications — industrial power applications such as firefighting and DC lighting.
A: The products support industrial communication protocols including RS-485, CAN, and MODBUS/TCP. DC panel controllers feature 4.3–10.2 inch touchscreen HMI interfaces with up to 4,096 error indications and multi-branch circuit monitoring. Battery monitoring devices are built on Cortex-M4 processors, supporting intelligent charge/discharge management and online battery monitoring.
