Product Advantages
Optimized for Communication Systems: Specifically designed for compatibility with program-controlled 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.
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 for 1 min, 12mA - No dielectric breakdown or flashover
Input to Output: 2KV AC for 1 min, 5mA - No dielectric breakdown or flashover
Output to Chassis: 500V AC for 1 min, 5mA - No dielectric breakdown or flashover
Application Scenarios
This module is an ideal power solution for:
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.
