Utility Inverter
Description
The most common application of direct to alternating current converter is in UPS (Uninterrupted Power Supply), which converts the battery power to 230 V or any other desired alternating voltage when there is a lack of city electricity. The conversion process here can also be done using linear or switch mode technology. In linear technology, DC voltage is first converted to AC voltage, then it is returned to alternating voltage with a certain range using a transformer and filter. In the switch mode method, the same work is done at high frequencies and using high frequency transformers.
Specifications of inverters:
- DC input: 24, 48, 110, and 220 volts
- AC output: 230 V or according to the order and requirement
- Output power: usually up to 30 kVA; Greater powers by order
