Dear colleagues.
Many from you, have repeated mine maiden, not a commercial charger
for model accumulators. Unfortunately, he contained many disadvantages.
Therefore, I have elaborated new a charger, with large capabilities.
At any rate, me he to like.
The new version can: To charge simultaneously 2 units (from 1 up to 10
Accumulators in the unit) nickel - cadmium or MG
accumulators, or two units (from 1 up to 4 accumulators in the unit)
Li accumulators, or two lead-acid cells on 12 V (for
modellers starter from UPC), or to discharge 2 units any
accumulators (up to 10 jars in the unit).
Thus, charger calculates capacitance, plots the chart, has
by memory for the schedules(charts), has a capability to select a charging current
within the limits of 50... 2500 mA to select pressure(voltage,stress) of switching-off
(cut-out) of category(discharge).
A power of the device, should be on 2.5 V more, than pressure(voltage,stress)
jn a charged accumulator bank.
For wishing, the scheme of the device of increase of pressure(voltage,stress)
is afforded(granted) automobile accumulator up to 19.5 V.
The principal diagram given charger. Is similar to the scheme mine previous charger.
The main(basic) differences: the processor AT Mega32, graphic is applied
the liquid-crystal indicator of the corporation WINSTAR: WG12864B-NGG-V with
by organization 128 on 64 points, microcircuit a DAP of the corporation MAXIM: MAX548,
and microcircuit TL494 in current regulators of each channel.
The commercial version includes:
Weaving of the processor, Principal diagram, Guideline on
to assembly, set-up and programming of a charger,
more in-depth photos of a charger.
In a kind(view) of a simplicity of a design, printed circuit card for a charger
was not designed(elaborated), and the charger collects on "General-Purpose IC PC Board".
The cost of the commercial version 75 Evro.
