·What is On Line Interactive UPS

The principle On Line Interactive UPS is not far off from Off-Line UPS, the main difference is that such products will be charged with the converter integrated circuit for bi-directional conversion circuit that can automatically detect the input voltage which is in line with the normal range. If bias can boost or buck voltage regulator circuit, it can provide a more stable output voltage. Its work principles are the same as with the off-line type.
