3.3 Introduction to 9PHD transformer cabinet
The 9PHD external transformer cabinet (TFC-A) can house one or two
transformers for the UPS system. You can use either isolation transformers or
autotransformers.
You can use the transformers for the UPS input line (a single feed that supplies
both rectifier and bypass inputs), rectifier input line, bypass input line or output
lines. Typically the transformer cabinet is used for input and output, or input and
bypass lines.
