Mike I have just found a 20amp 12v transformer SMPS for the sum of 36.99 which I consider to be very cheap. They come from Ripmax the model suppliers.

hi Gerald, The Ripmax transformer looks like the  sort used to give a regulated supply to CB base stations. At 20 amps output it is ok  for running waterpump, lights etc.  While you can charge a battery, its not ideal in that it is advisable to ocasionally  boost charge at approx 14.5 volts to desulphate the plates which is one reason for leasure batteries failing.

It is not a charger it is only a power supply, a charger has to be separate to the smps supply. they were never made as chargers and should not be used as one.

Mike I have posted the curcuit I am at present building for my Dandy, have a look it is not too tecnical. It has many advantages which I will name when I have written the instructions, basically if you are using one battery the other is charging, as long as you have 240v.

Hi art, yup there's been a few and the new seasons not underway for most people, and I have had two changes already. I have updated the Electrical dawing with some dialogue, on how it works.

Towsure do the Transformers, as we found out when we left ours at home.

Now have 1 to get the chiller down to temp before we leave and 1 that is kept in the Dandy.

Hi Sorry to keep posting the same question!!!!

Going to France again in the summer, taking our Dandy, and wondering if anyone can shed light on a problem we encountered with the continental electrics last year. We had 2 systems in place:

1.12V via the car battery, which we used for the water pump and internal light  - this was really meant to be used for times when we couldn't find hook ups

2. Electric hook -up with a power - breaker.

We found that even when we used a continental adaptor the electrics would not work(they work fine in the uk)We even borrowed an adaptor on site to make sure that ours wasn't faulty. Anyhow we spent 2 weeks and seemed to manage with just the car battery!

Could it be that the continental current doesn't have enough "umph" to reset the circuit breaker???
