Altronix eFlow4NBV is a power supply/charger converts a 220VAC (working range 198VAC – 256VAC), 50/60Hz input into a single 12VDC or 24VDC output. It also offers a suite of features that includes fire alarm disconnect, overvoltage protection, and low power disconnect which prevents deep discharge of stand-by batteries.
Features
Input Rating
- Input 220VAC (working range 198VAC – 256VAC), 50/60Hz, 2.1A
Output
- 12VDC or 24VDC selectable output
- 4A continuous supply current
- Filtered and electronically regulated output
- Aux. output rated @ 1A (unswitched)
- Overvoltage protection
Battery Backup
- Built-in charger for sealed lead acid or gel type batteries
- Automatic switch over to stand-by battery when AC fails. Transfer to stand-by battery power is instantaneous with no interruption
Supervision
