What this product is
What this product is
A compact 1U hot-pluggable AC-to-DC power conversion cassette incorporating patented soft-switching resonant bridge topologies, communicating digitally via an integrated CAN interface with Smartpack controllers.
What problem it solves
Eliminates excessive thermal dissipation and high operational cooling overheads while maintaining uninterrupted DC power across unstable utility grids prone to deep sags and extreme voltage surges.
Who and where it is for
Wireless base stations, broadband telecom access nodes, offshore platforms, railway signaling, and industrial control systems requiring redundant 24VDC rails.
Core advantages
- Utilizes a fully digital DSP topology and soft-switching resonant architecture, achieving up to 95.5% efficiency to significantly minimize thermal dissipation.
- Supports an ultra-wide AC input range of 85-300VAC, maintaining a stable 2000W full-load output under unstable grids and harsh EMC conditions.
- Features a 1U compact hot-swappable design combined with autonomous active current sharing for zero-downtime scalability and effortless maintenance.
- Engineered for extreme environments with an operating temperature of -40°C to +75°C and intelligent front-to-back forced air cooling.
