Altronix eFlow4NB

1-Output Power Supply Charger Board 12/24VDC 4A

eFlow4NB

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 Charging

• 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 non latching) 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.
