What this product is
What this product is
It is a fully integrated telecom-grade subrack combining AC input distribution, DC power distribution, an intelligent supervisory controller (M530S or M830B), and rectifier slots into an 11U 19-inch form factor, designed for demanding telecom architectures.
What problem it solves
Solves space-constrained macro site distribution issues, minimizes energy conversion losses with 96%+ efficiency, and prevents catastrophic battery depletion via independent LLVD and BLVD contactor schemes.
Who and where it is for
Telecommunication central offices, wireless macro cellular base stations (4G/5G), optical transmission repeater hubs, and enterprise telecom rooms.
Core advantages
- Compact high-density architecture consolidating 600A capacity into an 11U subrack.
- Wide AC input range (85VAC to 300VAC) eliminating frequent battery switchover.
- Advanced battery health management with temperature compensation and dual LVD circuits.
