1. Introduction

Tripp Lite’s S3MT-60K480V and S3MT-100K480V input isolation transformers provide 480V (Delta) to 208V (Wye) step-

down and Isolation protection to the connected UPS and its load. The S3MT-60K600V and S3MT-100K600V Input isolation

transformers provide 600V (Delta) to 208V (Wye) step-down and isolation protection to the connected UPS and its load.

The transformer has input isolation to mitigate utility line surges and spikes, while protecting the UPS. The transformer

includes a built in breaker at the transformer output side for protection. The ball-bearing fans maintain quiet operation (four

fans for 60K models, three large fans for 100K models). An overheat-sensing relay and switch combine with a warning light

to 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 rugged stainless steel housings with

front panels similar to the S3M-Series 208V 3-Phase UPS line.
