Description
Sola HS19B150 - SolaHD Buck-Boost Transformers are versatile, compact, and cost-effective transformers designed for voltage adjustments in a range of applications. They can be configured for various voltage combinations, typically lowering or raising supply voltage by 5 to 27%. These transformers comply with NEC Article 210.9, Exception 1 when used as autotransformers, offering efficiency and cost benefits compared to isolation transformers. They can handle loads up to 20 times their nameplate rating when used as autotransformers, making them ideal for small voltage adjustments. Additionally, they are suitable for low-voltage lighting control and landscape lighting applications, being UL Listed for outdoor use

Features
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.
