switches and various telecommunication equipment.
- Dual Input Flexibility: Supports both AC (187-253VAC) and DC (198-286VDC) input, allowing
for versatile installation in different power environments.
- Reliable & Smart Operation: Offers essential protection features (over-voltage, short-circuit,
over-temperature), remote monitoring via RS-485, and stable
parallel operation with excellent current sharing (<±5%).
- Compact & Efficient: Provides a compact footprint with over 90% efficiency, balancing
performance with energy savings for continuous operation.
Application Scenarios
- Telecommunication Infrastructure: Powering core network equipment, program-controlled switches, and
base station systems requiring reliable 48V DC power.
- General Communication Equipment: Serving as a dedicated power source for a wide range of
communication and electronic devices compatible with 48V systems.
- Small to Medium Backup Systems: Acting as a core component in DC power systems or battery backup
solutions for critical communication nodes.

Protection & Safety Features
- Automatic Current Limiting: Once the output current reaches the set current limit, the module
automatically switches to constant current operation, preventing
any further increase in output current.
- Overvoltage Protection: The output will automatically shut down if the voltage exceeds
62.5-63 VDC to protect connected equipment from damage.
- Short-Circuit Protection: During an output short-circuit, the module self-protects to
prevent damage. After the fault is cleared, normal operation is
automatically restored.
- Insulation Strength: Input to Chassis: 2KV AC 1 min 12mA | Input to Output: 2KV AC 1
min 5mA | Output to Chassis: 500V AC 1 min 5mA (No dielectric
breakdown or flashover)
