BB12-300-D3

Three-Phase 208/240 VAC High-Frequency Charger

The BB12-300-D3 is a three-phase 208/240 VAC high-frequency charger for 24V industrial batteries. The 208/240 three-phase platform is well suited to facilities where a 480 VAC drop is unavailable — it preserves the efficiency benefits of three-phase service on lower-voltage feeders. Multi-chemistry support and modular HF design make this a versatile choice for mixed-fleet battery rooms.
