Line Interactive Ups - Combined Inverter/converter, Faster Response To Power Failures, Noise And Spike Filtering

The main features of this design is that the Line Interactive UPS is always connected to the output, powering the equipment. This design allows for faster response to a power failure than a standby UPS. The inverter/ converter is also normally fitted with circuitry to filter out noise and spikes, and to regulate the power during brownouts and curtailing output during surges.

The Line-Interactive UPS is an improved design that is commonly used in units for home and business use. It is superior to the standby UPS, but it still has a transfer time, and thus does not provide protection as good as the online UPS.

The Line Interactive UPS uses a totally different design than any type of standby UPS. In this type of unit, the separate battery charger, inverter and source selection switch have all been replaced by a combination inverter/ converter, which both charges the battery and converts its energy to AC for the output as required.
