Description
HS19F3A Emerson Sola-HD Encapsulated Buck Boost Transformer 3.0 KVA, Maximum Secondary Amperage: 250 at 12V, 125 at 24V, 120 x 240 Volt Primary, 12/24 Volt Secondary
Buck-Boost transformers are small, single phase, dry type distribution transformers designed and shipped as insulating/isolating transformers. They have a dual voltage primary and a dual voltage secondary. These transformers can be connected for a wide range of voltage combinations. The most common use is to buck (lower) or boost (raise) the supply voltage a small amount, usually 5 to 27%. Buck-boost transformers are in compliance with NEC Article 210.9, Exception 1 when field connected as an autotransformer.

Benefits
cULus
Small‚ single phase‚ dry type distribution transformer
Dual voltage primary and a dual voltage secondary
Transformers can be connected for a wide range of voltage combinations
compliance with NEC Article 210.9‚ Exception 1 (field connected as an autotransformer)
They can handle loads up to 20 times the nameplate rating
More efficient than equivalent isolation transformers
It is an autotransformer when the primary and secondary windings are connected (larger kVA rating than the nameplate indicates)
Connected as an insulating transformer‚ the transformer’s capacity matches the nameplate kVA rating
