NP-LPS6-24VDC

LINEAR POWER SUPPLY

WI1325D 12/05

DESCRIPTION

This variable-purpose power supply is suitable for many differ­ent 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.

FEATURES

• Dip switch selectable 6VDC-12VDC-24VDC.

• 1.5 amp continuous supply current at 6VDC-12VDC.

• 1A continuous supply current at 24VDC.

• Filtered and electronically regulated output.

• Built-in charger for sealed lead acid or gel type batteries.

• Maximum charge current 300mA.

• Automatic switchover to stand-by battery when AC Fails.

• Circuit breaker battery protection (fused available).

• AC input and DC output LED indicators.

• Extremely compact design.

• Includes battery leads.

Board dimensions: 70mm L x 60mm W x 40mm H

Voltage Output/Transformer Selection Table:

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 con­nected in series for 24VDC operation.

Note: When batteries are not used, a loss of AC will result

in a loss of output voltage.
