S3MT-30KWR480V

1000 Eaton Boulevard Cleveland, OH 44122 United States SmartOnline S3MT-Series 3-Phase 30kVA Input (480V to 208V)/Output (208V to 480V) Isolation Transformers MODEL NUMBER: S3MT-30KWR480V Highlights ● Dual 30kVA/kW 480V transformers for government, healthcare and corporate settings ● Up to 97.5% efficiency with a quiet acoustic profile less than 65 dBA ● Resettable protection relay/switch and red alarm indicators warn against overheating ● Rugged stainless steel housing with compact footprint comes ready for installation ● Compatible with select 20–30kVA/kW S3M-Series 208V 3-phase UPS systems Applications Enclosure with step-down and step-up transformers offers line isolation and protection to the connected 3phase UPS and its load. Protect equipment in government, healthcare, manufacturing, corporate and other settings that have 480V electrical mains and 480V IT loads System Requirements Features Get Complete Step-Down/Step-Up and Isolation Protection S3MT-30KWR480V includes two transformers in a single cabinet: a 480V (Delta) to 208V (Wye) input isolation step-down transformer and a 208V (Wye) to 480V (Wye) output auto step-up transformer. It isolates the UPS and connected components from line surges and spikes caused by utility power disruptions that can damage equipment or corrupt data. The dual transformers are ideal for 4-wire (3Ph+N+PE) loads in government, manufacturing, healthcare and corporate settings with 480V electrical mains and 480V IT loads. Performs with High Efficiency up to 97.5% Not only is the S3MT-30KWR480V wrap-around transformer very efficient, with up to 97.5 percent efficiency, but it is also very quiet with a noise profile less than 65 dBA. Built-in circuit breakers on both transformers help prevent dangerous power overloads. Four ball-bearing cooling fans help prevent overheating. An overheat-sensing relay and switch combine with red alarm indicators to provide overtemperature warning and overheating protection. Small Footprint for Quick Installation in a Compact Space The compact footprint enables installation of the S3MT-30KWR480V with minimal space. The rugged stainless steel housing ships ready for immediate tower installation with a compatible 20–30kVA/kW S3MSeries 3-phase UPS system.

Thermal switches on input and output transformers will open the corresponding transformer breaker if either of the transformer reaches 155°C/311°F to 165°C/329°F. Once the transformer cools down to 120°C/248°F to 130°C/266°F, the corresponding warning LED light will turn OFF, and the corresponding transformer breaker maybe closed to restart operation.
