LIEBERT VSO42KUCOEI287A is a premium line-interactive uninterruptible power supply (UPS) designed for use in mission-critical applications. This unit features advanced sine wave output, extended runtimes, and optional NEMA receptacles for 200/208V single and three-phase applications. It also includes a communications port that allows connection to computers and network systems. LIEBERT VSO42KUCOEI287A is a true double-conversion online UPS, which converts incoming AC power into DC power, and then re-converts it into clean, regulated AC power. This ensures that sensitive IT equipment will continue to receive quality power, even during power disturbances such as brownouts, blackouts, and over-voltage conditions. The unit is equipped with an LCD display, which indicates line voltage, output voltage, battery voltage, load percentage, estimated battery runtime, estimated battery recharge time, and UPS status. The UPS offers a power rating of 42kVA/42kW and maximum currents of 65A, 120/208V. A maintenance bypass switch prevents interruption of the UPS output during maintenance operations, and an emergency power off (EPO) switch allows the unit to be safely powered down in an emergency. LIEBERT VSO42KUCOEI287A is suitable for installation in data centers, server rooms, or medium-sized industrial or commercial sites. The UPS includes two relay contacts for monitoring remote alarm events, and advanced battery management technology provides the highest level of chargers and replaceable batteries. Optional CPU port communication cards for network management are supported, along with external battery cabinets (up to 8) to increase the runtime capabilities. The unit is safety approved to UL 1778 and UL 1703; meeting CSA C22.2, NEMK1, and NEMK2 components. The power factor of the machine is nearly 0.99, making it highly efficient. LIEBERT VS042KUCOEI287A also offers hot-swap batteries, which can be replaced without taking the unit offline. The UPS features an internal fan, which is used to cool the system during operation. To provide high levels of protection to expensive IT equipment, the unit also includes EMI/RFI line noise filtering.
