Regulated power supply

[Hotkey]

I've taken Johno's advice and bought myself a 30ah deep cycle battery, for $145 from Positive Batteries but nobody here in town can help with a regulator. Just ordered my C8 but won't use the battery until it is regulated.
Does anybody have a suggestion where to look?

Hi Evan

I have purchased regulated power supplies (mains power adapters) from Jaycar and Duck Smith. However, these units are for plugging into a mains socket (230/240V AC) and provide me with the following: 12V DC 2A, 24V DC 4A and 12V DC 1A for the 3 different units I have.

But, it seems you are asking about a regulating unit that connects to your battery rather than the mains? If so, I haven't seen one on my travels, but perhaps someone else in the group has?

Cheers

Regulating a battery is a tall order if it's a 12V battery and your equipment is 12V as well. Any form of regulator needs a supply voltage several volts in excess of the final regulated voltage, e.g. to obtain a 12 volt regulated supply the voltage regulator will need approximately 17V or higher. Considering the battery voltage will vary between approximately 13.8 volts fully charged and around 11 volts fully discharged you have no need for regulation if the C8's nominal voltage is 12V and you are using only the battery. If you're intending on running the C8 on mains power then a switchmode 12 volt plugpack is the best alternative, is well regulated, cool running and affordable.

Why would you want to regulate a DC supply,coming from a DC source,you would only regulate a DC supply coming from an AC source .Just use the battery as is.

Dito to what Phil has said.

I just purchased an 80Amp h deep cycle battery and will be runnig everything off it like my laptop, camera's and mount.

Just make sure you use a quality charger atleast a 3 stage even 4 stage around 3-5amp charger is enough.

No need for regulators with 12v system...just plug & Play.

You will not get a better, cleaner source of DC, than from a battery. PURE as...A dead straight line....Nada, zip, NO ripple, etc etc...
What are you trying to do exactly? If just running t'scope n gear, then your chosen battery will suffice. To charge it, use at least a 4 Amp unit, but do not charge whilst using t'scope/laptopetc, unless the charger is a switch mode/regulated one. (actually, I would not recommend doing it anyway).
