Tired of hunting for batteries that are the right size or aren't dead? Now there is a solution! This convenient, fixed-voltage power supply substitutes for a wide variety of batteries including AA, AAA, C, D, and 9-volt types. Voltage is easily selected with the turn of a dial. Supply is precision designed so that the output voltage does not increase during adjustment between voltage ranges to protect your sensitive electronics. Connections are provided by two 4-mm banana jacks. A fuse in series with supply output provides short circuit protection. Plugs into a standard electrical outlet, 120 V AC, 60 Hz, 1 amp max.
