The TONHE TH230D05ZZ-220AC is a high-efficiency, fanless 5A intelligent rectifier module engineered specifically for 220VDC electrical control applications. This module provides the ideal balance between power density and physical footprint for compact wall-mounted power systems.
In wall-mounted DC power systems, space and noise constraints are critical. The TH230D05ZZ-220AC's compact cast-molded panel design fits perfectly into small wall cabinets without requiring clearance for air intake and exhaust. The fanless natural convection cooling eliminates noise and prevents dust accumulation, making it ideal for maintenance-free indoor installations.
Equipped with standard RS-485 communication, this module supports comprehensive remote functions. System operators can monitor power supply health in real-time, adjust output voltage (190V-300V range), and set current limits (10%-100%) without physical site visits.
Safety is paramount in power distribution. The module features "Foldback" short-circuit protection that automatically reduces output current to safe levels during faults, then resumes normal operation once cleared—minimizing downtime and protecting critical components.
High-tech enterprise integrating manufacturing, sales, system solutions, and after-sales service. Over 290 successful projects for 220 kV to 500 kV substations and battery systems above 1000 Ah. Leading DC power system supplier in China with over 40% market share and 1 million modules produced annually.
8 advanced production lines with 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 to ensure reliable 24/7 performance in critical power infrastructures.
Full range of power conversion modules, system-level low-voltage DC distribution cabinets for DC loads, data center power systems, and customized hardware and software power solutions.
Sample orders available for quality testing (customer pays sample cost). Payment accepted via TT (Telegraphic Transfer).
350+ elite R&D engineers with core team members from renowned domestic and international universities. Deep patent portfolio covering high-frequency soft-switching, digital control algorithms, and EMC design. Drafting unit for multiple power supply industry standards.
7x24 remote intelligent operations and maintenance with IoT technology for quick fault identification and solutions. Full product line passes CE, 9001, IEC certifications, complying with major global market entry standards.
