Descriere
Available in 16, 32 and 63 A, Liebert® CROSS Rack exists in both high voltage (230 V) and low voltage (120 V), single-phase input and single-phase output models.
Benefits:
– Ensures redundant power to critical loads
– Enables automatic transfer of the load to the priority line whenever its parameters fall within certain values
– Maximum reliability with redundant control logic
Features:
– Ability to switch between two alternative single-phase power sources
– The ‘fixed priority’ operational mode, allows the preferred input line to be selected
– BBM modality on both poles, thus ensuring that the two sources will never be directly connected
– CBEMA guidelines are met due to Chloride CROSS Rack ability to switch between independent AC power sources in both synchronous and asynchronous conditions, relative to the input waveforms
– Emergency switching, provides the transfer to the alternative source, in only a few milliseconds
– Ability to recognize downstream short-circuits that are caused by loads or distribution
