kead power supply
Dear all,
for a new design I've to setup a power supply unit power from main line (220 V) and also from a solar cell, also we need to have a battery backup unit inside the system.
At now I'm thinking to use a simple diode 80SQ040 and put this two as wired or from the battery charger unit and the solar charger unit.
To keep the system more simple as possible I'm thinking to set up the schematics attached (PDF).
The 5V output is to supply a KONTRON MOPSlcd7 mother board (5 V for 11 W of power consumption on the worst case), this line should be powered by a DC-DC converter model TEN20-2411WI TRACO POWER 20 W 5 V out), the two other DC-DC converter is to supply the hard disk (there is one into the system) a modem and one other PLC, we use a TEN20-2412WI TRACO POWER module, also power is enough for this applications. The last one DC-DC module (U3) is to power a DC motor with maximum current of 100 mA.
I've some question about the charging systems, at now we've see the Ansmann kead acid battery charger model 5207222/02 ALCT 12-3(**broken link removed**) and use it as external module to charge the battery trough the D2 diode.
What I like to know is of someone have some criticism about this type of connection, with regards the fact that the battery charger can be always attached to the board, may be this type of schema not good for such type of application? There is some resource regarding small UPS or other better solution that I can take a look?
I'm very gratefully if someone can take a look on it.
Thanks in advance
