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. The NP-P5A
power supply/charger converts low voltage AC input into 6VDC,
12VDC or 24VDC @ 5 amps of continuous supply current (see
features). .
FEATURES
Maximum charge current 300mA.
Automatic switch over to stand-by battery.
Battery short circuit protection (circuit breaker).
Thermal overload and short circuit protection.
AC input and DC output LED indicators.
Extremely compact design.
Includes battery leads.
Dip switch selectable 6VDC-12VDC-24VDC output.
5 amps continuous supply current at 6VDC-12VDC-24VDC*.
Filtered and electronically regulated output.
Built-in charger for sealed lead acid or gel type batteries.
Board dimensions: 96.52mm L x 76.20mm W x 60mm H
*
Specified at 25° C ambient.
INSTALLATION INSTRUCTIONS
The NP-P5A should be installed in accordance with The National
Electrical Code and all applicable Local Regulations.
1. Mount the NP-P5A in desired location/enclosure.
2. Set DC output voltage with dip switches (refer to Voltage Output/
Transformer Selection Table).
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. 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 use 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.
