48VDC to 220Vac Modular Inverter System N+1 Parallel Redundancy 0ms Seamless Transfer 3KVA Rack Mount Telecom Power

Price Negotiable
Price: 1 USD/pc
MOQ: 1 piece
Delivery Time: 3-4 weeks
Brand: Ding Future
Product Description

Engineered specifically for mission-critical telecom base stations and data centers where downtime is not an option.

This modular system utilizes advanced N+1 redundancy technology and 0ms seamless switching between AC and DC inputs.

Supports "Plug-and-Play" hot-swapping, ensuring that the load remains uninterrupted even during module maintenance or single-point failures.


Key Features : 

  • Power Density: 2000W per module, scalable up to 6KVA in parallel.
  • Transfer Time: True 0ms seamless transfer between AC bypass and Inverter mode.
  • Redundancy Logic: N+1 parallel connection without master/slave dependency; no single point of failure.
  • Input Specs: 48VDC (42V-58V) & 220VAC (176V-265V) dual-input backup.
  • Output Quality: Pure sine wave output with THD < 3% for sensitive electronic protection.


Usage / Applications

    • DC power backup systems for Telecom/Mobile base stations.
    • Standard 19-inch server rack power distribution in data centers.
    • Emergency power for core network switching rooms.
