Key Features
Dual Input & High Power, Stable Output
Supports 220V AC/DC dual input with ±15% wide voltage tolerance, adapting to complex power grid environments in outdoor/remote areas. 12KW high power, 200A output at 48V meets the power demand of multi-device concurrent operation in medium and small communication stations.
High Efficiency & Energy Saving
System efficiency up to ≥96%, matching high-performance rectifier modules TH48D30NZ-S-3/TH48D50NZ-S-3, effectively reducing power consumption and operation costs for long-term running communication equipment.
Intelligent Monitoring & Comprehensive Management
Equipped with dedicated THJK020-48V monitoring unit with LCD display and key operation. Real-time monitoring of bus voltage/current, battery status and module working parameters. Supports automatic equalization/floating charge management with temperature compensation, current limiting and other battery protection functions. Optional battery inspection module realizes real-time detection of 2V/12V battery cell voltage.
Multi-protocol Communication & Remote Functions
Supports RS232/485, SNMP communication protocols, compatible with Modbus protocol. Dual background communication enables remote tele-measurement, tele-signaling and tele-control. 16 switch input and 16 switch output interfaces provide flexible linkage with peripheral equipment, fault alarm and signal output.
Comprehensive Alarm & Protection Systems
Full-range fault alarm (over-voltage/under-voltage, over-current, over-temperature, module fault, etc.) with Chinese character display of alarm information for clear fault location. Stores 4096 historical faults and 2048 operation records (power-off non-volatile). Built-in buzzer and red light flash alarm with customizable alarm thresholds for all-round system operation safety.
Compact Design & Easy Deployment
4U rack-mounted embedded design, size only 482*400*177mm, suitable for 19/21 inch cabinet installation, saving space for limited equipment room in edge communication nodes. Simple wiring and humanized operation interface requires no professional technical personnel for on-site debugging and operation.
Superior System Performance
  • Powerful Expansion: Maximum 4 rectifier modules with flexible configuration according to actual power demand; supports matching of battery inspection module, insulation monitoring unit, etc.
  • Stable Operation: DC48V standard communication power supply with 40-60V wide working voltage range, adapting to voltage fluctuation in outdoor power grid.
  • Fault Self-recovery: Built-in watchdog circuit and comprehensive protection mechanism with automatic fault alarm and linkage processing, ensuring no interruption of core communication equipment power supply.
  • Data Storage: Real-time clock (power-off normal operation) with long-term storage of fault and operation data for convenient maintenance and data analysis.
Ideal Application Scenarios
IoT & Edge Computing
Smart Transportation
Rural & Remote Area Communication
Security & Monitoring
Emergency Communication
Traditional Communication Stations (4G/5G mobile base stations)
