The Amperor 12v Regulated Power Supply 2.1mm D1119 is designed to provide a stabilised 12 volt supply to sensitive electronic equipment used in caravans, motorhomes and boats. In these environments the typical voltage can vary from 10 volts to 15 volts depending upon the state of the battery, what else is being used inside the vehicle and whether the battery is being charged or not at the time.
Many electronic appliances such as TVs and laptops are not designed for such a wide variation of input supply and cannot tolerate this level of swings in voltage. It can be frustrating when watching a favourite TV programme and the TV switches itself off, just because a water pump is operated. Worse still, manufacturers of LCD TVs advise that models which nominally operate on 12V are damaged by voltages over about 13 volts. TVs that should last for years are being severely damaged within a few months. Such is the problem that some TV manufacturers are saying that their warranty is void if their TVs are used on unregulated 12-volt supplies.
The answer is to use one of these units which will provide a stabilised 12-volt output even if the input varies between 10 volts and 28 volts. The higher voltage specification allows 12-volt TVs to be powered from a 24-volt supply if required, making this product ideal for use in commercial vehicles too.
