APC E3SUPS20K3I | Easy UPS 3S 20kVA Online UPS, 3:1 Phase, 400V, External Batteries

The APC Easy UPS 3S 20 kVA is an online double conversion UPS with a 3:1 topology — three-phase 400 V input delivering clean single-phase 230 V output — purpose-built for small and medium data centres, healthcare, telecoms, and manufacturing environments. With zero transfer time, unity output power factor, and efficiency exceeding 96% in double conversion mode (99% in ECO mode), it delivers continuous power conditioning without interruption. Supplied without internal batteries, this unit is designed exclusively for use with external battery cabinets, enabling flexible runtime configuration and simplified capacity scaling.

Parallel operation supports up to three units (maximum 60 kVA) for capacity expansion or N+1 redundancy, while a wide input voltage window (304–477 V) minimises battery usage during minor disturbances. Front-access servicing, integrated input/output/bypass breakers, an Emergency Power Off switch, and optional SNMP remote monitoring make this UPS easy to manage in demanding deployments. Replaceable dust filters and conformance-coated boards extend reliability in harsh environments. Available now at iptrading.com.au — competitive prices and local support.
