Altronix EFLOW4NV Power Supply Charger, Single Output, 12/24VDC @ 4A

Altronix eFlow4NV is a power supply/charger converts a 220VAC (working range 198VAC - 256VAC), 50/60Hz input into a single output. Power supply/charger is selectable for 12VDC or 24VDC with a total of 4A max. They also offer 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

• 220VAC (working range 198VAC - 256VAC), 50/60Hz, 2.1A
• Input fuse: 5A/250V

Output

• 12VDC or 24VDC selectable output
• 12VDC or 24VDC @ 4.0A supply current
