Introduction - Tripp Lite S3MT Series Owner's Manual

1. Introduction

Tripp Lite's S3MT-100KWR480V is a 480V Wrap-Around Transformer that includes two transformers in one enclosure: a
480V (Delta) to 208V (Wye) input isolation step-down transformer and a 208V (Wye) to 480V (Wye) output auto step-up
transformer.
The input isolation transformer mitigates utility line surges and spikes, while protecting the UPS. The output auto transformer
is designed to support 480V (Wye) IT loads. This model has built-in circuit breakers to prevent dangerous circuit overloads.
Eight ball-bearing fans maintain quiet operation and help to dissipate transformer heat. An overheat-sensing relay and switch,
combined with an LED light in the front panel, provide over-temperature warning and overheating protection. The UPS system's
small footprint and quiet acoustic profile enable installations with minimal space and noise impact. The transformer features a
rugged all-metal housing with a front panel similar to the S3M-Series 208V 3-Phase UPS line.
UPS Model Series Number
