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 3-phase 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.
