eFlow4NBV

Power Supply Charger, Single Output, 12/24VDC @ 4A, Aux Output, FAI, LinQ2 Ready, 220VAC, Board

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.

  • 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 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.
