Hey everyone,
I am trying to troubleshoot a board that had been damaged by water recently. The function of this board is to check for a signal from a probe, and if that signal is not present, to turn off the relay which controls an in-series device. I have checked the transformer output, the...
Ok thanks everyone, I just wanted to make sure I understand this. I see the note you are referring to about the DC and AC electrical characteristics. So if it is only 5V that is DC, and if it is AC they would indicate 5Vac or something similar. Thanks again all.
Thank you for the reply. When I look at the datasheet though, say for a LM555, it does not state 4.5V to 16V DC, it just says 4.5V to 16V. In general with datasheets, if it does not specify AC or DC, we just assume DC? Thanks again for the replies, I know this is probably a trivial question...
Hey all,
I have a general question about the 555 timer. I am looking at the datasheet and the supply voltage says 5V to 16V range. Is this AC or DC power? I does not really state whether it is AC or DC. Thanks for your help.
I already had planned on using a 555 timer charge control circuit with trimmers to adjust the high voltage and low voltage states for charging, so I only really needed to ensure that the voltage did not get above 15V or so. This charge controller is less expensive than I thought, which is...
I just researched purchasing a charger IC and they are more cost effective, although, they are hard to find at 60V input (special order). I would be hesitant to use the charger IC with the 60V input because there will not be much room for variation (i.e. the input voltage swings up to 70V for a...
Hello All,
This is my first post here, so we will see how this goes. I am designing a charging circuit for lead-acid batteries and I believe I need to have some kind of control of the voltage, particularly for over voltage. The system generating the electricity has a DC output in the range of...
