RELAY AS SWITCHER

[repax]

help naman kung anung relay ang applicable para sa automatic switch namen.. may dalawa kame 12V battery... gsto ko sana manyari e magswitch ung supply from battery A to battery B kpag lowbat n ung battery A.. same goes den kpag lowbat ang Battery B..

any help will be highly appreciated

thanx

[KANGARO]

well ATS circuit can be use..

kung parehas lang ang chemistry capacity tsaka voltage rating ng BatteryA at Battery b baka mas makakabuti kung iparallel nalang

sir can you post a circuit diagram for ATS ciscuit??

or e2 sir para mas madaling maexplain.. meron den kc akong battery indicator at may display xang LED lights.. meron xang 9 LEDS... 3GREEn, 3yellow, 3red. nababwasan ung ilaw nia habang nababawasan ang charge ng battery. gsto ko sana e mag switch ang battery A to BAttery b kpag lowbat na or sa sa mdaling salita kapg ung LED dispaly e nasa red n lang..

use a window comparator

sir, wala b jang ung di maxado complicated sir..  kc ang inooperate lang naman ng dalwang battery ko e dalwang 24V DC motor.  gsto ko lang naman magswtich ang battery kpag nalowbat ung isa. ung mejo mdali dali sir. and sir penge ng mga link para mas maintndhan ko pow.. thanx pow master

pinakasimple na yan at wala na ring ibang paraan para malaman mo kung mahina na ba yung battery mo

anung klaseng relay po b ang the best? kc ung sa ATS circuit di ko maintndhan e.

[marcelino]

try to google comparators (using op-amps). using comparator, one could set a range of voltage so that to make the voltage output as high or low.

observe the following  images... note the voltage input as the wiper of the variable resistor is being varied. of course observe the relay switch position.








just some notes, (a) R1 and R2 are the reference voltage divider and (b) the output of the comparator op-amp is either high or low (almost 5V and almost 0V).

from this concept you can now design your own switch. google mo nalang ang tamang caculations,etc.
you could use, LM193/293/393 as the comparator. you could actually directly connect that to the battery. it got a wide range of voltage capacbility... up to 36V yata.

wala bang relay n available sa market na double throw. nkakabit n ung dalwang battery dun.. tpos may isang pin n magaacept ng 1 or 0 na signal.. kpag nkareciv ng 1 nsa battery A xa.. kpag 0, nsa battery B ang supply?


ung dalwang battery is 12V 7.2A

isang Single pole double throw lang ang kelangan mo tulad ng relay sa schematic ni sir marce kung yung isang line lang yung icucut mo, halimbawa nun eh kung nakacommon yung negative nila

[repax]

di ko kc maintndhan ung schematic n pinost ni sir marce e.. di ko alam kung panu ko isesetup ung battery jan. newbhie lang po kc ako sa electronics e. paxenxa n mga master.. kaya po nagahhanap ako ng relay n nabibili na para po mas mdali sana.

[repax]

mga master.. e2 may relay akong nabili... panu ko isesetup toh as battery switcher.. NAIS JQ1 12V

[nucleus]

ito po pakianalyze nalang:



yung unang connection single pole lang yung relay nakacommon yung negative ng battery
yung pangalawang connection double pole ang relay hindi nakacommon yung negative

[repax]

SALAMAT PO NG MARAME MASTER ALJUR

welcome sir and wag nyo rin pong kalimutang pasalamatan yung ibang tumulong

cool!!! wahahaha rami kong natutunan hehehehe ayos ung post na ito... namromroblema din ako kung pano ung presentation ng battery kapag batt a at batt b using relay. maraming salamat!!!

may kulang po yang circuit....


put rectifier diode in series with the battery...to avoid back pedal ng current in time mag charge ang battery....
