Introduction; Typical Applications; Key Features - Tripp-Lite S3MT-Series Manuel De L'utilisateur

1. Introduction

Tripp Lite's S3MT-30KWR480V and S3MT-60KWR480V are 480V wrap-around models that include 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. These models have built-in circuit breakers to prevent dangerous circuit overloads.
Four ball-bearing fans for S3MT-30KWR480V and eight ball-bearing fans for S3MT-60KWR480V maintain quiet operation
and help to dissipate transformer heat. An overheat-sensing relay and thermal 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. All transformer models feature stainless steel housings with
front panels similar to the S3M-Series 208V 3-Phase UPS line.
