More than just power.


Altronix eFlow104NB UL Listed Sub-Assembly power supply/charger converts a 120VAC, 60Hz input into a single 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 120VAC 60Hz, 4.5A.
  • Output:

  • 24VDC output.
  • 10A. 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:
