U4898A VEHICLE BATTERY POWER CONVERTER INSTRUCTIONS FOR USE
U4898A VEHICLE BATTERY POWER CONVERTER INSTRUCTIONS FOR USE
PAG Vehicle Battery
Power Converter
Model No. 9774
Instructions For Use
General
This small, lightweight, economic unit converts the vehicle’s 12 volt
battery output to 300 volts DC, and is ideal for powering equipment
employing switch-mode power conversion techniques. The unit provides a
powerful 120 watts continuous output and allows short term use up to
150 watts. This power is sufficient to run 12V AR Series chargers and the
integral chargers of all Pagbelt IC2s.
The unit is fitted with a plug for direct connection to the vehicle’s cigar
lighter socket. A red LED indicates connection to the vehicle battery. To
turn the unit off, simply disconnect it from the cigar lighter socket. (The
vehicle cigar lighter socket and wiring harness must be capable of carrying
a minimum current of 10 amps).
The unit incorporates an audible warning system which operates when the
vehicle battery needs to be boosted by starting the vehicle’s engine.
However, if the vehicle’s engine is not started and the battery voltage
continues to fall, the unit will switch-off (latch out), leaving enough
power to start the vehicle. Unplugging the unit will reset the latch. Then,
after boosting the vehicle battery, reconnect the unit.
Suitability
This unit is only suitable for use with vehicles having the negative of the
battery connected to the chassis - ‘negative earth’.
The output of the unit is only suitable for equipment employing switch-
mode power conversion, and is not to be used with equipment that
incorporates a primary mains transformer.
DISREGARD OF THIS CAUTION COULD RESULT IN DAMAGE TO CERTAIN
EQUIPMENT TYPES.
Note that a simple test may be done to determine the compatibility of
equipment to be used with the unit. Using a meter, measure the resistance
between the live and negative pin of the equipment’s mains plug. With its
switch on a resistance reading of greater than 10,000 ohms indicates that
the input circuit is suitable for use with the Vehicle Battery-Power
Converter, provided that its load does not exceed 120 watts. If in doubt
consult your PAG Dealer or a qualified electrical engineer.
Connection
Plug the unit into the vehicle cigar lighter socket, using the cable-
mounted plug. Power is then available on the standard IEC output lead.
Unplug the unit when not in use, otherwise it will continue to draw
current, slowly discharging the battery.
Specification
Output: 300V DC,
power available is 120 watts maximum, with 150W short
term capability.
In use the unit draws about 1 amp from the battery for every 10 watts of
actual load applied.
Self Protection System
If overloaded the unit will switch-off (latch-out), requiring momentary
disconnection from the vehicle battery/cigar lighter socket to reset.
It is advisable to run your vehicle engine occasionally if an extended
period of use is required.
The unit incorporates an audible warning system which operates when
battery voltage falls below 11 volts, with a safety low voltage latch-out at
10 volts. This will leave enough power in the battery to start the vehicle.
