TONHE Floor Standing Telecommunication DC Panel With Hot Swappable Charger Modules

The core function of the Communication Power Supply Panel is to convert 380V/220V AC power into stable 220V DC power through high-frequency rectifier modules during normal AC power supply, providing continuous power to communication equipment while simultaneously managing battery float charging; when mains power fails or grid abnormalities occur, the system automatically and seamlessly switches to battery backup power, with the battery bank directly outputting DC power to communication loads, ensuring that critical communication facilities such as base stations, network rooms, enterprise private networks, rail transit signaling systems, and new energy communication sites, can continue operating when the main power source fails, guaranteeing 7*24 hours uninterrupted and stable operation of communication networks.

Tonhe Electronics Communication Power Supply Panel utilizes advanced high-frequency switching power technology, integrating intelligent rectifier modules, DC distribution units, monitoring & control systems, and battery management devices, with automatic dual-grid input switching capability. The system is equipped with comprehensive electrical protection functions, including over-voltage, under-voltage, over-current, short-circuit, over-temperature protection, and lightning surge suppression, effectively eliminating power pollution issues such as grid harmonic interference, voltage fluctuations, and electromagnetic interference.

The panel is equipped with an intelligent battery management unit (BMU) compatible with VRLA (Valve-Regulated Lead-Acid), Gel, and Lithium-Ion battery types.

Core Features:

• Auto Float/Equalize Charge with temperature compensation
• Real-time battery monitoring (voltage, current, internal resistance
• Automatic protection activation upon battery abnormality detection
• Silicon chain voltage reduction device with hot-standby switching capability
• Hardware-based current sharing with ≤5% maximum current imbalance
• Remote monitoring & AI predictive maintenance capability
• This comprehensive battery management extends battery service life and enhances overall system reliability.

The product is manufactured from high-quality cold-rolled steel plate with electrostatic powder coating treatment, featuring excellent corrosion resistance and wear resistance. Standard cabinet dimensions can be customized according to customer requirements, with common specifications including: 800mm(W)*600mm(D)*2000mm(H), 1000mm*800mm*2200mm and other size options. Both front and rear doors are equipped with safety locks, with reasonable internal space layout for easy equipment installation and maintenance. Protection rating can reach IP30/IP40 standard, adapting to different installation environment requirements. The cabinet interior adopts modular design with independently installed functional units.

The Tonhe Electronics Emergency Lighting Panel is designed and manufactured in strict adherence to core International Electrotechnical Commission (IEC) standards, ensuring global compliance and ultimate reliability. The product fully complies with IEC 62040-1 (Safety requirements for UPS) and IEC 62040-3 (Performance and test requirements), authoritatively validating its exceptional 0ms seamless transfer and online inverter power supply performance. It simultaneously meets the IEC 60529 ingress protection standard (IP30/IP40) for diverse installation environments and adheres to the IEC 61000 series for Electromagnetic Compatibility (EMC) to eliminate grid interference. The battery system passes the UN 38.3 international transportation safety test, and the complete unit is produced under the ISO 9001 Quality Management System, providing power safety assurance that meets the highest international specifications for critical facilities worldwide.
