UPS Topologies

“Voltage independent” UPS in compliance with IEC 62040-3, also known as line interactive, protects against the most common power problems experienced in a network. Here the UPS also monitors the voltage level and balances under and over voltages. The VI technology offers a good compromise between reasonable security and moderate operating costs.
