Its Weldon Battery Eliminator (1.5V To 12V, 500mA). A battery eliminator is a device that is powered by an electrical source other than a battery and then converts the source to a suitable DC voltage for use by a second device that is battery powered. The rectified dc output voltage of the battery eliminator is 1.5-12 volts. And the Output 1.5-12V DC in steps of 1.5, 3, 4.5, 6, 7.5, 9,12 volts. Battery eliminator is used in place of ordinary dry batteries as power source for equipment like radio receivers AM/ FM, tape recorders, calculators etc. and other low power operated equipment .
