DE-SWADJ Adjustable Voltage Regulator These adjustable voltage regulators by Dimension Engineering are one of the most useful things to have handy. Unlike normal voltage regulators, these are "switching regulators" which are extremely efficient. When using battery power, this is important. A typical application is to power a digital camera on an aircraft and save weight. It means you can power almost anyhting from the flight pack of an electric aircraft. Maximum continuous current drain must not exceed 1Amp. The input can be anything up to 30V and the output is adjustable between 2 and 13V. Data Sheet If you require more than 1 Amp power, see the 3 Amp version of this regulator: 25W Step down adjustable switching regulator If you require fixed 3.3 or 5 volt, refer to the Fixed Voltage Regulators: 3.3V Regulator 5.0V Regulator Weight approx 10g For reference, the official Canon A/C adaptor for the A620 and A640 is 5.8 volts, center positive. They draw about 70mA with the LCD off, and about 200mA with it on. Price: (USD) $17.10 Shipping from: $1.76 In stock now
