[QUOTE="Geoff1946, post: 514613, member: 28452"] The average load is no issue, neither is where you source the 230volt supply, (well under 1 amp). There are many DC supplies e.g. at CPC, but these are regulated units which would probably shut down if there is a start-up surge. You really need something much simpler, like a transformer rectifier with ample over-capacity and no electronics. Virtually a car battery charger. I don't know where you could find one ready made designed for the purpose, and agree that the makers should supply or recommend one. Otherwise, perhaps you could get away with a 12volt supply, perhaps 10amp, intended for CCTV fitted with a small lead acid dry battery which would absorb the start up surge? [/QUOTE]
