Charge a small battery from a large one, or from an automobile, truck, tractor or back-hoe. This DC converter automatically converts any voltage from 8V to 16V to 13.8V for battery charging. It has a active current limit of 8 amps. It also features total isolation so the input ground is galvanically isolated from the output ground. This could be used for charging negative grounded batteries in a postitive ground car, and vice versa.
Inexpensive fully isolated taper style controlled lead acid battery charger voltage charger with 8 VDC to 16 VDC input. Used to charge 12 volt lead acid batteries when only DC voltage is available. It cannot overcharge the battery.
Remote Turn-on When +12V is applied to the brown wire of the input harness the unit will turn on if the rocker switch is turned off.
A: Yes, the output is fully isolated from the input, so there is no danger in confusing grounds.
A: Yes, When the charger detects that the battery voltage has dropped it knows that the battery needs to be charged and goes into "constant current" mode again automatically.
Q: Can I charge my 12 volt golf caddy from my car?
Yes, the charge time should be less than 2 hours for a fully depleted golf trolley.
Charging wheel chairs, bicycles, golf trollys and scooters in a car, van or bus.
Output short circuit and battery polarity protections.
Charging 12 volt "jump start" batteries from a 12 volt tow truck or service vehicle.
Charging 12 volt electric bicycle from a vehicle.
The PST-PB1108 converts 12 volt power into 13.8 volt power for charging, so for an 8 amp output the input needs over 9 amps. Make sure that the wires connecting the PST-PB1108 are adequate for the current and the length of the run. If the voltage drop in the wires are too much the "Low Battery Voltage" alarm will come on. Wires that are too small may also overheat and melt the insulation, causing a dangerous situation. 12 gauge is usually adequate for runs up to 20 feet of wire (adding together the positive and negative wire lengths).
Mount the PST-PB1108 in an area that will get adequate ventilation and will be free from rain, spray, or excessive dust.
