Offline UPSDolphin DysonUPS offlien Dolphin

The OFFLINE UPS supplies (or routes) the incoming mains supply directly through to the output usually through a relay contact. Some high frequency noise filtering and surge suppression may be included in this path. The UPS switches on its inverter as soon as mains supply failure is detected or below the normal load and simultaneously switches the output relay to the inverter side to supply battery sourced power to the load. This transition involves a delay on account of the time to reliably detect mains failure and switch over a relay, and the output is broken for this period (usually for 2 to 12msec).

OFF – LINE UPS are usually the least expensive as compared to the other two.

What exactly is Off-Linetechnology?

Off-Line is the simplest protection. The PC continues to receive power through the electrical network but without energy conversion. In the event of a problem such as power outages or voltage changes, the UPS is supported by batteries in order to stabilize the voltage. The use of this technology is appropriate for the protection of PC’s, work stations, passive terminals and low range servers.
