UMD: Power supplies designed to deliver an almost steady, predetermined value of AC voltage (e.g., 120 V) for a limited range of input line voltage variations (e.g., plus or minus 10%). These devices typically include an electronic line voltage monitor to detect line voltage fluctuations and some electric or electronic stabilization circuit or device to compensate for these variations. Line voltage stabilizing power supplies are mostly used to maintain normal operation of electrical equipment (e.g., motors, pumps, lights, refrigerators) under reduced-voltage conditions (brownouts).
