1. Three stages variable charging voltage algorithm by timing for maximizing the battery lifetime
2. Large charging capacity design (40A for 12Vdc mode, 20A for 24Vdc mode) for shortening the charging time
3. Selectable charging currents based on connected battery capacity for extending battery lifetime with optimized charging current
4. Multiple voltage charging design for protecting diverse types of batteries of Flooded Lead-Acid, Gel, AGM chemistries batteries
5. Wider input voltage range from 90Vac to 280Vac for universal input
6. High AC to DC converting efficiency design (higher than 80%)
7. Smart fan control -Build-in fan control firmware for controlling fan on/off status bases on charger operating mode. When the battery is charged, the fan will stop to reduce the noise and also extend the fan lifetime.
