In addition to the protection offered by UPS units, Liebert® CROSS Rack ensures a further level of safety, having the ability to switch between alternative power sources. The advanced control ‘break before make’ (BBM) switching feature, provides high safety for all loads in all operational modes and its reduced dimensions make it ideal for mission-critical environments where the footprint is a key issue.

Best Suited For:
– Banking
– Financial and Insurance
– Data Center/Colocation/Hosting
– Healthcare
– Retail and Wholesale

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.

– 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

– 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
