eFlow102NBV - Power Supply/Charger
Rev. EF102NBV-32715
Overview:
The eFlow102NBV power supply/charger converts a 220VAC (working range 198VAC - 256VAC), 50/60Hz input to a
12VDC @ 10A output.

Installation Instructions:
Wiring methods shall be in accordance with the National Electrical Code/NFPA 70/NFPA 72/ANSI, the Canadian
Electrical Code and with all local codes and authorities having jurisdiction. Product is intended for indoor use only.
1. Mount the eFlow102NBV in desired location/enclosure.
2. Connect unswitched AC power (220VAC 50/60Hz) to terminals marked [L, G, N] (Fig. 1a, pg. 3). Use 14 AWG or
larger for all power connections. Secure green wire lead to earth ground.
Keep power-limited wiring separate from non power-limited wiring (220VAC 50/60Hz Input, Battery Wires).
Minimum 0.25” spacing must be provided.
CAUTION: Do not touch exposed metal parts. Shut branch circuit power before installing or servicing equipment.
There are no user serviceable parts inside. Refer installation and servicing to qualified service personnel.
3. Measure output voltage before connecting devices. This helps avoiding potential damage.
4. Connect devices to be powered to terminals marked [-- DC +] (Fig. 1h, pg. 3).
For auxiliary device connection this output will not be affected by Low Power Disconnect or Fire Alarm Interface.
Connect device to terminals marked [+ AUX -- ] (Fig. 1f, pg. 3).
5. For Access Control applications batteries are optional. When batteries are not used, a loss of AC will result in
the loss of output voltage. When the use of stand-by batteries is desired, they must be lead acid or gel type.
Connect battery to terminals marked [-- BAT + ] (Fig. 1g, pg. 3). Use one (1) 12VDC battery. Use batteries - Casil
CL1270 (12V/7AH), CL12120 (12V/12AH), CL12400 (12V/40AH), CL12650 (12V/65AH) batteries or UL
recognized BAZR2 batteries of an appropriate rating.
Input Rating:
• Nominal 220VAC (working range 198VAC - 256VAC),
50/60Hz, 2.1A.
Output:
• 12VDC output.
• 10A continuous supply current.
• Aux. output rated @ 1A (unswitched).
• Overvoltage protection.
• Filtered and electronically regulated outputs.
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 & 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.
Visual Indicators:
• Green AC Power LED indicates 220VAC present.
• AC input and DC output LED indicators.
Additional Features:
• Short circuit and overload protection.
