Hammond Transformers - Hammond QC50ESCB 500 VA 120/240 Volt Primary 16/32 Volt Secondary 1-Phase Lighting Transformer

The advantages of using a buck-boost transformer over an equivalent standard isolation transformer are used in a variety of applications, Inexpensive, smaller and lighter, more efficient, 5-10 times increase in kVA. Buck-boost transformers offer an economical solution to the adjustment of line voltages that are slightly above or below normal. When a buck-boost transformer is connected as an autotransformer, only a portion of the load kVA is actually transformed. The majority of the load kVA is passed directly through to the source. For this reason a buck-boost transformer may be used to supply a much larger kVA load than is indicated on the nameplate. Buck-boost transformers can be used to adjust stable voltages only.
