NP-P10A

10 AMP POWER SUPPLY / CHARGER

WI1328C 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. The NP-P10A
power supply/charger converts low voltage AC input into 12VDC
or 24VDC @ 10 Amps of continuous supply current (see fea­tures).

FEATURES

• Maximum charge current 700mA.

• Automatic switch over to stand-by battery.

• Thermal overload and short circuit protection.

• Battery is fuse protected.

• AC input and DC output LED indicators.

• Includes battery leads.

• Dip switch selectable 12VDC-24VDC output.

• 10 Amps continuous supply current at 12VDC-24VDC*.

• Filtered and electronically regulated output.

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

Board dimensions: 179.32mm (L) x 108.71mm (W) x 60mm (H)

Specified at 25° C ambient.

wiring (115VAC / 60Hz Input, Battery Wires). Minimum .25"
spacing must be provided.

3. Set the NP-P10A to the desired DC output voltage by setting the
switches to the appropriate positions (see Voltage Output/
Transformer Selection Table).

4. Connect devices to be powered to terminals marked [+ DC -].

Note: It is important to measure output voltage before connecting

devices to help avoid potential damage.

5. When the uses of stand-by batteries are desired, they must be

lead acid or gel type. Connect battery to terminals marked [+
BAT -] on the unit (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 the

loss of output voltage.

AC Low voltage AC input (see Voltage Output/Transformer Selection Table).

For 12VDC output use 28VAC with 175 VA power rating or higher.
For 24VDC output use 28VAC with 300VA power rating or higher.
Caution: Do not apply voltages above 28VAC (28VAC is maximum input rating).

+ BAT -- Stand-by battery connections.

+ DC -- DC output voltage for devices to be powered.

Function/Description

INSTALLATION INSTRUCTIONS

The NP-P10A should be installed in accordance with The National

Electrical Code and all applicable Local Regulations.

1. Mount the NP-P10A in desired location/enclosure.

2. Connect proper transformer to terminals marked [AC]. (See

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
