Description
EFLOW3NBV 12VDC OR 24VDC @ 2A 220V
Altronix eFlow3NBV 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.
Input Rating
Input 220VAC (working range 198VAC - 256VAC), 50/60Hz, 2.1A.
Output
12VDC or 24VDC selectable output.
2A continuous supply current.
Filtered and electronically regulated output.
Aux. output rated @ 1A (unswitched).
Overvoltage protection.
Battery Charging
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.
(Batteries are sold separately).
Supervision
AC fail supervision (form "C" contacts).
Notification trigger is selectable for 30 seconds (factory set) or 2 hours.
Battery fail and presence supervision (form "C" contacts).
Low power shutdown. Shuts down DC output terminals if battery voltage drops below 71-73% for 12V units and 70-75% for 24V units (depending on the power supply). Prevents deep battery discharge.
Fire Alarm Disconnect
Supervised Fire Alarm disconnect (latching or non-latching) 10K EOL resistor. Operates on a normally open (NO) or normally closed (NC) trigger.
