What this product is
What this product is
A standard 19-inch rack-compatible telecom power conversion unit designed to transform raw single-phase AC utility or generator power into stabilized -48V DC power while simultaneously managing VRLA/Lithium battery strings.
What problem it solves
Eliminates network outages caused by volatile grid spikes or brownouts, drastically curbs operational expenditure through high-conversion efficiency, and prevents catastrophic battery degradation via independent dual low-voltage disconnects.
Who and where it is for
4G/5G macro and micro base transceiver stations (BTS), fiber optical line terminals (OLT), transmission repeaters, enterprise core switches, and industrial utility sub-stations.
Core advantages
- Ultra-wide 85VAC to 300VAC input operational tolerance with intelligent linear derating under low-voltage conditions.
- Over 96% peak efficiency, substantially minimizing thermal dissipation requirements and overall facility PUE.
- Hot-swappable modular construction with autonomous active current sharing (imbalance <±5%) for zero-downtime maintenance.
- Integrated advanced battery health algorithms including programmable temperature compensation, boost/float regulation, and dual LLVD/BLVD.
