Battery Chargers
On-board charging for EV platforms, railway rolling stock, and industrial equipment demands chargers that handle wide input voltage swings, survive −40°C cold starts, and scale from auxiliary battery maintenance to full traction pack replenishment. Bel battery chargers span 3W to 25kW output, accepting 85 ~ 1100 VAC single- or three-phase input to deliver 12 ~ 860 VDC, with convection, fan, and liquid cooling options across Bel and Melcher™ product lines.
