Line-Interactive UPS

Power supply is fed through surge and noise suppression circuitry and built-in line conditioning circuitry regulates high or low voltages back to normal levels, and sends clean power to equipment without using battery power. A battery charger keeps an internal battery topped up and ready for use whenever required. During a blackout, an inverter switches on and converts battery power into a simulated sine-wave output, and switches off when normal power resumes while the battery is recharged again. The switching process between regular power and inverter power happens in milliseconds and does not affect performance of appliances being powered by or through the UPS.
