BB24-400-E3

Three-Phase 480 VAC High-Frequency Charger

The BB24-400-E3 is a three-phase 480 VAC high-frequency industrial battery charger for 24/36/48V batteries. Three-phase 480 is the standard incoming service in most warehouse and manufacturing battery rooms — it delivers more power per circuit, lower cable losses, and the highest efficiency available on this platform. The HF design supports multi-chemistry batteries with auto-load equalization and module auto-bypass for fault-tolerant operation.
