6. POWER SOURCE
To get the best performance out of your converter, we recommend
that you use it with the vehicle’s engine running.
Your average automobile or marine battery at full charge will
provide an ample power supply to the converter for approximately
3 hours when the engine is off. The actual length of time the
converter will function depends on the age and condition of the
battery and the power demand being placed by the device being
operated with the converter.
If you decide to use the converter while the engine is off, we
recommend you turn OFF the device plugged into the converter
before starting the engine. To maintain battery power, start the
engine every 2 to 3 hours and let it run for approximately 10
minutes to recharge the battery.
Although it is not necessary to disconnect the converter when
turning over the engine, it may briey cease to operate as the
battery voltage decreases. While the converter draws very low
amperage when not in use, it should be unplugged to avoid battery
drain.
7. LED INDICATOR AND SHUTDOWN PROTECTION
The LED glows GREEN when the switch is on, and under the
following conditions:
1. When the power input from the vehicle’s battery drops to
approximately 10 volts, low battery shutdown occurs and the
converter shuts off. The Green and Red LEDs are on, with a
buzzer. Solution: Recharge or Replace the battery.
2. When the power input from the vehicle’s battery exceeds 15
volts, high voltage overload protection occurs. The Green
LED is on, but the buzzer will not sound. Solution: Reduce the
voltage range to between 12 volts and 14 volts.
3. The continuous load demand from the equipment or device
being operated exceeds the continuous load rating of the
converter being used. The output pulses ON and OFF; the
Green LED is on. Solution: Use a higher capacity converter or
lower rated device.
