Power suply unit for 300 charger?
Where I can find a schematic and layout diagrams for switcher who is a charger for Motorola GP300 batery? That is "ASTEC model AAI6600".
GP300 power cube...
Most Circle-M power cubes are just that, and not switchers, they are 'raw D.C' at about 18 volts, the 'switching' is performed in the charger base of the rapid rate charger, and current limited in the standard 10 hour charger.
You can use any D.C wall cube with the rapid rate base as long as the current capability is greater than 1.5 amps, that's why the base can be used in a vehicle as well as at home...the power cube does not have the ability to 'make up' for high current demands needed for charging a depleted pack as a car battery has.
I've used 18 volt D.C computer supplies with my Jedi rapid rate charger and it works just fine, just make certain the plug polarity is correct, the base will let out the smoke fast if it's reversed.
The lower the current capacity of the cube, the longer it takes to charge the battery. But the power cube you choose must be capable of at least 13 volts under load, or quickly rise to that level soon after the charger begins its cycle as the regulators and current sensing circuits in the rapid rate base require a minimum voltagecurrent to properly charge the pack using feedback for temp sensing/current demands over time.
Just my 1/120th of a gallon of information.....
