More than just power.


Altronix eFlow4NBV 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 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:

  • 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.
