Liebert NXb 30 kVA includes maintenance by-pass

MLiebert NXb 30 KVA is a mid-sized, three-phase uninterruptible power supply (UPS) system that delivers complete, centralized data center power protection. Designed to meet the high availability power needs of a wide variety of IT applications and equipment, the UPS combines compact size, advanced operating features and low cost of ownership.

Description :

Liebert NXb 30 KVA includes a maintenance bypass – 208 volt, internal batteries and line and match maintenance bypass are included with this UPS system. It is supported by a one year parts warranty. Start up and comprehensive service agreements are available. We have tested this UPS under load and installed new High Rate UPS batteries.

The hardware and firmware for parallel UPS module operation is standard in the Liebert NX, and the configuration can be set up by changing the settings in configuration software. It is easy to install the parallel cables in a ring, providing high reliability and redundancy. And the intelligent paralleling logic provides the user with maximum flexibility. For example, shutting down or starting up the UPS modules in the parallel system can be done in any sequence. If an overload transfer occurs, the whole system can recover automatically from bypass mode after the overload is cleared. The total load of the parallel system can be queried from each module’s LCD screen. Optional monitoring background software can treat the entire parallel system as a big single module UPS, and provide corresponding management. It can also get the information for all modules by connecting to just one of the modules.
