Hercules HD series ( Virtual Online) [ Range: 650VA 10Kva ]
This LI UPS is widely used for PC applications and some medical equipments also. It is having Built in AVR to regulate the mains voltage to offer wide input window. Its transfer time from mains to Inverter is very less and it is synchronized with the Input mains supply, so you can fell there is no transfer time even using a oscilloscope, so this series of Line interactive UPS is called virtual online UPS.
Applications: Mainly used for PCs in Cyber cafÃ©, computer labs in school ,colleges, Training institutes, cad centers, etc.
