Block compact LBP + UZU


Greetings to all reasonable! I decided to make a compact, universal memory + LPB, for my own needs, so to speak. Apart from himself, the predecessor of the memory had to separately transport the connecting wires, the power cord, they are constantly confused, they get in the way that you will agree not to eat Ice ...

Basis: ATX BP on PWM TL494. Adjustable for voltage and current. I think it makes no sense to describe the alteration of the ATX, there is a lot of information on the Internet, I reworked according to this scheme:
Block compact LBP + UZU

The predecessor had automatic operation on reaching 15 volts (auto Battery). In this option, I refused automation. During operation, it turned out that the automation is triggered when the programmed voltage is reached, but the charge does not occur to the desired value. Now I put 15 V and 5 A on the ultrasonic control and when the charge is reached, the amperage drops, the battery takes as much as he needs, the automation is not needed, an extra freeloader in the circuit.

I took out a gift box (on February 23, 2015) for small things, tried on a converted board from ATX, prepared the tools, components and started manufacturing.




From the duty room I made a 5 volt output for charging a smartphone, tablet, etc.

Exit

Voltage and current adjustment (no handles, made with a glue gun)



Floor case place for connecting wires

To charge a screwdriver

Wires for avotAKB

Wire connection

Crocodiles for use as LIP



Here is such a compact UZU, LPS turned out




Aesthetics are not enough, but at least like this:



Good luck to all!

Uh, for sure! (c) Red Army Sukhov.
Functionally correctly resolved, but, of course, the front panel is horrible. ((
Replace it, fasten it with screws, put normal handles, maybe put the clamps better - there will be a sample for repetition.

Hand it for the smartphone ...
