The CIRCUITRON PS-2 is an AC to DC converter and voltage regulator that will provide a constant 12 volt DC output under varying load conditions and/or variations in input voltage. The PS-2 has a maximum output of 1 amp and a maximum input voltage of 18 volts AC. Note: The PS-2 will achieve maximum output capacity if the input voltage is 14 volts. Higher voltages may result in a reduction in output current capacity. If the supply voltage is less than 14 volts, the output voltage may not stay Regulated and may drop below 12 volts, especially at higher current draws. The PS-2 is constructed on a 3? square printed circuit board, and a section of CIRCUITRON?s Printed Circuit Mounting Track (PCMT) is provided for simple, snap-in mounting.
