Altronix eFlow4NBV Power Supply Charger - Single Output

Altronix eFlow4NBV Power Supply Charger - Single Output

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.

Key Features:

• 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.

• 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.

• Electrical

    • Operating: 0° C to 49° C (32° F to 120° F).
    • Storage: - 20° C to 70° C ( - 4° F to 158° F).
  • Relative Humidity 85% +/- 5%.

  • BTU/Hr (approx.):

    • 12VDC: 25 BTU/Hr.
    • 24VDC: 49 BTU/Hr.
  • System AC input VA requirement: 462VA.

• Visual Indicators

  • AC input, DC output, and Battery LED indicators.

• Additional Features

  • Short circuit and overload protection.
