MaximalFEV Expandable Power Systems - 3 -
MaximalFEV Overview:
Maximal Expandable Power Systems provide system designers and installers with optimum power choices
and the highest levels of versatility. They provide 12VDC, 24VDC, or 12VDC and 24VDC simultaneously via
two (2) single output power supply/chargers. Includes AC fail, low battery, and battery presence monitoring.
Enclosure facilitates up to four (4) 12VDC/12AH batteries.
MaximalFEV Features:
Input:
• 220VAC (working range 198VAC - 256VAC),
50/60Hz.
Output:
• For output voltage and supply current, refer to
MaximalFEV series Configuration Chart, pg. 4.
• Auxiliary power-limited output rated @ 1A
(unswitched).
• Overvoltage protection.
Battery Backup:
• Built-in charger for sealed lead acid or
gel type batteries.
• Maximum charge current 1.54A.
• 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 non latching) 10K EOL resistor. Operates on a normally
open (NO) or normally closed (NC) trigger.
Supervision:
• AC fail supervision (form “C” contacts).
• 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.
Fuse Ratings:
• Refer to MaximalFEV series Configuration Chart,
pg. 4.
Visual Indicators:
• Green AC Power LED indicates 220VAC present.
• AC input and DC output LED indicators.
Additional Features:
• Short circuit and overload protection.
• Unit is complete with power supply, enclosure,
battery leads and cam lock.
