The different types of UPS technologies |
| Off-Line or Passive Stand-By |
| The most frequently-used technology for protecting PCs in low-interference environments. In the normal mode, the UPS supplies power to the application from the main supply, simply filtered but without any conversion of energy. Its principle of operation is sequential (via the main supply/via the battery). In the event of a cut-out, low or high voltage, the UPS stores its energy in its battery in order to deliver a stable power supply. It is not suitable for using in the case of frequent disruptions industrial or severely disrupted environments). |

| Line-Interactive |
| In normal mode. The device is controlled by a microprocessor which monitors the quality of the electrical system and reacts to any variations. A booster, a fader and voltage compensation circuits are activated in the event of any variation in voltage amplitude. |

| Double-conversion(On-Line) |
