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.
