The 110V DC power supply panel is a core DC power supply assembly specifically designed for power systems, industrial automation, rail transit, and other fields. It is suitable for AC 50/60Hz, input voltage AC 380V (three-phase) / 220V (single-phase), and provides a stable output of 110V DC. Its main function is to efficiently convert AC power into DC power, providing uninterrupted, high-precision DC power supply to precision loads such as relay protection devices, circuit breaker operating mechanisms, PLC control systems, and signal equipment. As the "power heart" of critical equipment, it is widely used in 35kV and below substations, power plants, data centers, communication base stations, petrochemical DCS control systems, rail transit signal centers, and industrial distribution rooms. It ensures stable operation of core equipment under grid fluctuations and sudden power outages, preventing equipment misoperation, data loss, or production shutdowns caused by power supply interruptions.

This product adopts fully digital control technology and a high-frequency soft-switching architecture, integrating a charging module, battery bank, monitoring unit, and distribution unit. It optimizes power conversion efficiency and output stability, allowing flexible configuration of the number of charging modules and battery capacity. It features intelligent charging management, remote monitoring, and fault self-diagnostics, effectively addressing pain points such as unstable DC voltage, insufficient backup time, and inconvenient maintenance. It achieves precise control, high efficiency, energy savings, safety, and reliability in DC power supply while adapting to different load scales. Parallel expansion capability meets the demands of high-load scenarios.

The product strictly complies with national and industry standards such as DL/T 5044-2014 "Technical code for design of DC power system for power engineering" and GB/T 19826-2014 "DC power supply equipment for electric power", and has passed CCC and ISO9001 certifications. It uses first-tier domestic brand components, with the core charging module adopting third-generation silicon carbide (SiC) or gallium nitride (GaN) power devices. The entire production process undergoes full quality inspection. The protection level can reach IP30 or above, featuring excellent dust and foreign object resistance. Suitable for indoor installation environments such as equipment rooms and distribution rooms, it ensures long-term stable service and meets the stringent requirements of various core equipment for uninterrupted 110V DC power supply.

Technical Parameters

Product Features

1. High-Efficiency Power Conversion, Energy Saving
The core charging module uses third-generation SiC/GaN power devices and high-frequency soft-switching technology, achieving full-load conversion efficiency of up to 95.2%, saving more than 7% energy compared to traditional modules. A single module saves over 3,600 kWh annually, helping enterprises achieve green and low-carbon transformation. Wide voltage input design (AC 85–340V) adapts to grid fluctuations and unstable voltage conditions in remote areas, preventing equipment shutdown caused by abnormal input voltage and ensuring power supply continuity.

2. High-Precision Output, Suitable for Precision Loads
Output voltage accuracy ≤ ±0.3%, ripple factor ≤ 0.12%, providing clean and stable DC power to meet the stringent power quality requirements of precision equipment such as relay protection devices, PLCs, and sensors, preventing equipment misoperation, data loss, or damage caused by voltage instability. Output voltage is continuously adjustable from 90–130V, compatible with different brands of battery banks, flexibly adapting to various application scenarios.

3. Intelligent Charging Management, Extends Battery Life
Features intelligent three-stage charging management (constant current, constant voltage, float charge), automatically switching charging modes based on battery status. Combined with battery temperature compensation algorithm (-4mV/℃·2V), it prevents overcharging or undercharging that can cause battery swelling or capacity degradation, extending battery service life to more than 5 years. Supports parallel operation of multiple charging modules with automatic current sharing (current distribution error ≤ ±3%), preventing individual module overload and improving system reliability.

4. Multiple Protections, Safe and Reliable
Built-in five-level protection mechanism of "prevention-monitoring-protection-recovery-diagnosis" ensures comprehensive system safety: Input side features overvoltage, undervoltage, phase loss, surge suppression, and lightning protection (8/20μs 10kA impulse current). Output side features overvoltage lockout, undervoltage alarm, overcurrent current limiting, short-circuit foldback, and reverse battery polarity protection. Temperature protection uses NTC temperature sensors and intelligent temperature-controlled fans. Strong cooling starts at ≥85℃, derated operation at ≥95℃ to prevent thermal runaway. A single module fault is automatically isolated without affecting other modules, supporting N+1 redundancy.

5. Intelligent Monitoring, Convenient Maintenance
Integrated intelligent monitoring unit with standard RS485/CAN bus interface supports Modbus RTU/TCP protocols for seamless connection to power monitoring systems, enabling "four remote" functions (remote measurement, remote signaling, remote adjustment, remote control). Remote viewing of operating parameters such as voltage, current, and temperature, parameter setting, and fault alarms. Equipped with a high-definition display panel for intuitive display of equipment status and fault codes, helping maintenance personnel quickly locate problems. Supports hot-swappable function, allowing faulty modules to be replaced without power interruption, reducing system downtime.

6. Modular Design, Easy Expansion
Modular layout with charging modules, monitoring unit, distribution unit, and battery bank in separate zones, ensuring neat wiring and easy maintenance and expansion. The number of charging modules and battery capacity can be flexibly configured based on load requirements. Supports parallel expansion up to 80A (as standard) to meet future load growth without requiring reconstruction. Standard 19-inch rack-mount design allows easy installation in standard distribution cabinets, saving equipment room space, especially suitable for space-constrained retrofit projects.
