DESCRIPTION
This variable-purpose power supply is suitable for many differ-
ent applications for security, access control and CCTV system
accessories that need supplementary power. NP-LPS6-24VDC
power supply/charger converts low voltage AC input into 6VDC
or 12VDC (@ 1.5 amps or 24VDC @ 1A of continuous supply
current). See specifications that follow.

INSTALLATION INSTRUCTIONS
1.
Mount NP-LPS6-24VDC in desired location / enclosure.
2.
Unit is factory set for 12VDC. For 6VDC output dip switch
2 off, for 24VDC output dip switch 1 on.
3.
Connect proper transformer to terminals marked [AC] (refer

to Voltage Output/Transformer Selection Table).
Use 18 AWG or larger for all power connections (Battery,
DC output).
Keep power limited wiring separate from non-power
limited wiring (115VAC / 60Hz Input, Battery
Wires). Minimum .25" spacing must be provided.
4.
Devices to be powered should be connected to terminals
marked [+ DC] and [– DC] carefully observing polarity.
Note: It is important to measure output voltage before con-
necting devices. This helps avoid potential damage.
5.
Connect battery to terminals marked [BAT +] and [BAT –]
(battery leads included). Use two (2) 12VDC batteries con-
nected in series for 24VDC operation.
Note: When batteries are not used, a loss of AC will result
in a loss of output voltage.
