The Power Inspired VFI-B series are rackmountable, occupying onlly 2U of rack space. They are true online double conversion systems providing the highest degrees of power protecton with the added benefit of being extendable in runtime and the option of adding in SNMP or relay cards for remote monitoring or local alarms.
The KR series are tre online double conversion Uninterruptible Power Supplies with high capacity chargers. The KR series has the benefit of being only 440mm deep, allowing a long runtime solution for low depth 600mm racks.
Both the VFI-B and KR can also be mounted vertically (or horizontally without being rack mounted), and if rackmouting capability is not required then the VFI-T Series provides similar features to the VFI-B but in a tower format.
