HS20F5A Emerson Sola-HD Isolation Transformer 120V, 240V 5000VA Buck Boost Transformers,5.0 KVA, Maximum Secondary Amperage: 312 at 16V, 156 at 32V, 120 x 240 Volt Primary, 16/32 Volt Secondary
Buck–Boost Transformers
SolaHD 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.
The major advantages of buck-boost transformers are their low cost, compact size and light weight. They are also more efficient and cost less than equivalent isolation transformers. When connected as an autotransformer, they can handle loads up to 20 times the nameplate rating. A buck-boost transformer is the ideal solution for changing line voltage by small amounts.
When a buck-boost has the primary and secondary windings connected, per recommended instructions, it becomes an autotransformer. Now, only the secondary windings are transforming voltage and current. The majority of the kVA load passes directly from the supply to the load. This is the reason buck-boost transformers can supply a load with a much larger kVA rating than the nameplate indicates.
Low voltage lighting control applications
SolaHD Buck-Boost Transformers are designed to supply power to low voltage lighting circuits, control panels or other systems requiring 12, 16, 24, 32, or 48 Volts. When connected as an insulating transformer (by following the wiring diagram located after the specification tables on the inside of the transformer case), the transformer’s capacity matches the nameplate kVA rating.
SolaHD Buck-Boost Transformers are also suited for low voltage landscape lighting. They are UL Listed for outdoor service and their compact size makes them the perfect solution for providing power to accent lighting applications.
