Shinwoo Power’s inverter control of uninterruptible power supply (UPS), based upon
synchronized changeover, is an epoch-making product that has totally and innovatively
resolved common problems of existing UPS systems such as unreliable synchronized
changeover, noise, momentary loss of power, low efficiency and unstable output voltage.
The system is designed to stand a short circuit at the load. In the case that the short at
the load was not resolved even after changeover, the system with its state-of-the-art
protective circuitry will shut down automatically.
Also, the maker’s frequency converter is currently strongly recommended, especially
for those customers who would like to export their products to the country whose electric
power frequency is different from their own. Or import products from the country whose
electric power frequency is different. It conveniently converts frequency of electric power
from 60 Hz to 50 Hz or from 50 Hz to 60 Hz.
The system converts electric power to DC with an AC-DC converter and then converts the DC back to AC 50
or 60 Hz with a DC-AC inverter which generates a clean sine wave. The voltage regulation of the converter is ±1%.
