1000 Eaton Boulevard Cleveland, OH 44122 United States SmartOnline S3MT-Series 3-Phase 20kVA Input Isolation Transformer, Delta 480V to 208V Wye, TAA Highlights ● Recommended for government, manufacturing, healthcare and corporate settings ● Up to 96.5% efficiency with a quiet acoustic profile less than 65 dBA ● Resettable protection relay/switch and red LED indicator warn against overheating ● Rugged stainless steel housing with compact footprint comes ready for installation ● Compatible with 10–20kVA/kW Tripp Lite S3M-Series 3-phase UPS systems MODEL NUMBER: S3MT-20K480V Applications Protect healthcare, manufacturing, corporate and other IT equipment where the upstream power source is 480V and the load requires a 208V 3-phase UPS 20kVA/kW transformer provides 480V (Delta) to 208V (Wye) step-down and isolation protection to a 3phase UPS and its load. Package Includes ● S3MT-20K480V 3-Phase 20kVA Input Isolation Transformer ● Owner’s manual Features Get Complete Step-Down and Isolation Protection and Prevent Power Disruption Tripp Lite’s S3MT-20K480V 20kVA/kW transformer offers line isolation and protection to the connected 3phase UPS system and its load. 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 step-down input isolation transformer is ideal for 4-wire (3Ph+N+PE) IT loads in government, manufacturing, healthcare and corporate settings with a 480V electrical feed and 208/120V equipment. Performs with High Efficiency up to 96.5% Not only is the S3MT-20K480V very efficient, with up to 96.5 percent efficiency, but it is also very quiet with a noise profile less than 65 dBA. A built-in circuit breaker on the output side helps prevent dangerous power overloads. Two ball-bearing cooling fans help prevent overheating. An overheat-sensing relay and switch combine with a red LED indicator to provide over-temperature warning and overheating protection. Small Footprint for Quick Installation in a Compact Space The compact footprint enables installation of the S3MT-20K480V with minimal space. The rugged stainless steel housing ships ready for immediate installation with a compatible 10–20kVA/kW Tripp Lite S3M-Series 3-phase UPS system.

Once the transformer temperature has cooled down to 125°C ± 5°C, i.e. a range of 120°C to 130°C ( 248°F to 266°F) the warning LED light will turn OFF, and you may manually reactivate (close) the output breaker on the transformer to restart normal operation.
