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 over-temperature 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 S3M-Series 3-phase UPS system.

LED Warning Light Functions | The over-temperature warning LED light will turn ON when the output/secondary of the Input transformer reaches 160°C ±5°C and will turn OFF wthen the corresponding transfomer cools down to 125°C ±5°C |
Over Temperature Reset | The transformers include an over-temperature protection relay and thermal switch on the secondary sides of the input (T-in) transformer and on the primary side of the output (T-out) transformer to protect the transformer from overheating. 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. |
