    Question about ACS758 current sensor

    The sensed input is essentially floating and I'm not sure if a bec arrangement would be any good in that respect. They normally operate as common ground.

    Question about ACS758 current sensor

    Yeah...model gear is a bit over-rated as to what it can handle. I think somewhere they say the unit is 50A with 100A being intermittent. Just how intermittent is not quoted but I guess it covers their ass ....:D I think with many of the previous sensors, it is possible to add external shunts...

    Question about ACS758 current sensor

    Don't think that is possible. As an alternative there is a ready made unit for around AU$12.00 from Ebay........ used one for ages and seems to keep going. No reason to bother with building/ bits and pieces when these are available at this price...

    Sounds like your browser could be storing the log in screen somehow. Sometimes on Google Chrome, I have to go to "settings" then when that opens, scroll down to "advanced ^" then click on "clear browsing data".

    Sign in now also takes two tab button press whereas before only one. Result is one ends up with an error message.

    Power supply ratings

    Output voltage is 24V, that's it. Current drawn will depend on your circuit BUT only to a maximum of 5Amp. Suggest you do a bit of basic electrical 101.

    Solenoid drawing barely any current -- is this normal?

    Agree with #2 BUT a bit of a gamble buying anything without any specs what-so-ever, especially at that price.

    Transistor alternative

    Slip-up. Some normal people have them from time to time.

    Transistor alternative

    Anything using a 3 to 10v bulb has to be ancient even for someone like me and I'm retired. I'd say use the same arrangement and any npn transistor such as the bc327 and in place of the bulb put an LED and resistor.

    Can some please tell me which is consider to be pin1 here

    Perhaps just a note included with your order and maybe even a spec sheet on the device drawing their attention to the pin arrangement shown at the end.

    BMS for Lithium Iron phosphate battery bank LiFePo4

    Classy installation......o_O

    Can some please tell me which is consider to be pin1 here

    Unless they are assembling the board, it won't matter.

    Reading 24 V signal

    I think that if PNP open collector the diagram should be the other way around' with the signal line to the micro taken from pin 4.

    How to power one or two of these clusters

    At $3 I'd just suck it and see do-to-speak.

    How to power one or two of these clusters

    Appears they connect directly to 12v dc. At 8w a piece you would need around 1.5A (or more) supply capability to drive 2 units in parallel.

    Reading 24 V signal

    I think you will find the sensor is open collector pnp.

    Li-Ion battery: Too much voltage?

    No longer have it. Battery was a standard 40Ah car lead acid battery.

    Li-Ion battery: Too much voltage?

    Your calculation 20Ah at 10A discharge is incorrect at 2.5 hours. I make it 2 hours BUT discharge capacity is wholly dependant of the discharge rate and one has to consult the manufacturer discharge curve to arrive at a close figure. I say "close" as all batteries are slightly different. I...

    Li-Ion battery: Too much voltage?

    As I said previously, we used one of these little units to power a 12ft aluminium boat with all our fishing gear, beer, ice, two people and had no bother with using an everyday lead acid battery. I think you are being a bit over the top really with any modification. The drive system and the...
