Power Supply - Valet System One Installation Instructions Manual

POWER SUPPLY

Requirements
A Regulated 13.8V DC power supply is required to power the system.
The required current rating of the supply will vary depending on the size of the
system and is equal to the sum of the current draw of each unit used.
CURRENT DRAW - MASTER - 350 mA peak
An 800 mA power supply will operate a system comprising of 5 Room/Door Stations.
A 2 Amp power supply will operate a system comprising of 13 Room/Door Stations.
(or a Master and 11 Room/Door Stations)
A 3 Amp power supply will run A Master and 17 Room/Door stations.
Multiple Supplies
Multiple power supplies may be used to provide additional current however
their output voltages need to be identical to minimize power losses.
Standby Battery (Optional)
Many 13.8 V power supplies accommodate the use of a standby battery which
may be used to allow the entire system to run in the event of a mains power fail.
The duration of battery backup is dependant upon:
a) the size of battery(s) used
b) the number of stations connected
A system using a 12V 6.5AH battery with ten stations connected to a master,
will run for approximately three hours with music playing at a moderately high
volume. (six hours with music turned off)
- STATIONS - 150 mA peak
- AUX O-P BOARD - 60 mA per board
