Altronix eFlow6NB UL Listed Sub-Assembly power supply/charger converts a 120VAC, 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.

Specifications:

• Input Rating

  • Input 120VAC 60Hz, 3.5A.

• Output

  • 12VDC or 24VDC selectable output.
  • 6A continuous supply current.
  • Aux. power-limited output rated @ 1A (unswitched).
  • Over Voltage 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.

• 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 80% of nominal. Prevents deep battery discharge.
