Emerson 20kVA UPS The Emerson 20kVA UPS (now under the Vertiv brand) is a high-performance, true online double-conversion uninterruptible power supply designed for critical infrastructure such as data centers, telecom systems, hospitals, and industrial equipment. It delivers clean and consistent power by isolating connected loads from input disturbances like voltage fluctuations, surges, and harmonics. With an output power factor of up to 1.0, the Emerson 20kVA UPS ensures maximum power availability and efficiency—often reaching over 95% in online mode and up to 99% in ECO mode. Key features include advanced digital signal processing (DSP) control, wide input voltage tolerance, generator compatibility, and optional battery scalability for extended backup. Built to handle demanding environments, it supports parallel configurations (N+X redundancy) and offers smart communication options like SNMP, Modbus, and dry contacts for remote monitoring. Emerson UPS systems are known for their rugged reliability, low total cost of ownership, and are backed by strong service support through the Vertiv network.
