This listing is for a VERY rare Zig DCU-15 power supply unit for caravans and motorhomes. It has been tested and is in good working order. It has a mains input (when connected to EHU) and has a 12v DC output to power your 12v appliances lights, fans fridge etc. And also to charge your leisure battery. I don't know a huge amount about this apart from it is very rare and in good all round condition.
I was going to keep it in my old motor home, but have decided to modernise the electrics, so have bought a newer unit. For anyone wishing to stick with vintage parts, then this is ideal. Alternatively, collection in person from Milton Keynes is also an option.
