230v to 12v at home

[GeekOKent]

There is a bunch of kit bought to be used on the road, in the lanes and at campsites. Now I want to use it at home, and don't really want to get a battery out, connect to a charger or use solar to keep it topped up.

There are a few mains to 12v adapters, just looking for recommended options that club members have used in the past/present.

Looking to peak at 15 amp@12v

I have this sort of thing for Ham radio

Compact 0-24 VDC Switching Power Supply The MFJ-4218MV has adjustable output from 0 to 24 VDC. You can power more than your HF or VHF radio.

I use a desktop power supply but that can only output 10amps, if you need 15amp you could use something like this

Many server PSUs are easily capable of 80A to 100A at 12V. A cheap source in terms of $/A but do require a bit of hacking, most of the big brands will be documented online and require a pin or 2 to be sorted or joined by a resistor. Worth checking this before a purchase though.

Something like this would suit KB. Would need fitting in an enclosure to prevent contact with terminals. 25A so a bit of headroom on your 15A. DC 5V-24V Universal Regulated Switching Power Supply 1A-60A 10W-480W LED 3D PSU | eBay - [Leaving Land Cruiser Club]

Otherwise as mentioned a CB power supply would suffice but these are usually 10-12A.

Your spoilt for choice really with PSU’s for Ham radio use. The cheapest are the switch mode type but perfectly adequate. Linear PSU’s are favoured by purists but they‘re usually bigger, heavier and more expensive.
