Extended Runtime UPS

Extended runtime UPS provides you with an advanced line of interactive power protection for your servers and network equipment. These units don’t have batteries in the internal unit, but they have an extended charger which allows you to attach multiple battery units to extend the runtime well beyond the typical limits of the standard UPS units.

Browse our extended runtime UPS collection below or get in touch with us today if you have any further queries regarding our range.
