eFlow4NB

Power Supply Charger, Single Output, 12/24VDC @ 4A, Aux Output, FAI, LinQ2 Ready, 115VAC, Board

Altronix eFlow4NB UL Listed Sub-Assembly power supply/charger converts 120VAC, 60Hz input into a single 12VDC or 24VDC Class 2 Rated power-limited 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 120VAC 60Hz, 3.5A.
  • Output
    • Class 2 Rated power-limited output.
    • 12VDC or 24VDC selectable output.
    • 4A continuous supply current.
    • Aux. Class 2 Rated power-limited output rated @ 1A (unswitched).
    • Overvoltage protection.
    • Filtered and electronically regulated outputs.
  • 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.
    • (Batteries are sold separately).
  • Fire Alarm Disconnect
    • Supervised Fire Alarm disconnect (latching or nonlatching) 10K EOL resistor. Operates on a normally open (NO) or normally closed (NC) trigger.
  • Supervision
    • AC fail supervision (form "C" contacts).
    • Notification trigger is selectable for 30 seconds (factory set) or 2 hours.
    • Battery fail & 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.
  • Electrical
      • Temperature:
        • Operating: 0° C to 49° C (32° F to 120° F).

    • Relative Humidity 85% +/- 5%.
      • BTU/Hr (approx.):
        • 12VDC: 25 BTU/Hr.
        • 24VDC: 49 BTU/Hr.
  • Visual Indicators
    • Green AC Power LED indicates 120VAC present.
    • AC input and DC output LED indicators.
  • Additional Features
    • Short circuit and overload protection.
