Frequently Asked Questions
What is a SolaHD Buck-Boost Transformer?
SolaHD Buck-Boost Transformers are small, single-phase, dry-type distribution transformers with dual voltage primary and secondary. They are designed to buck (lower) or boost (raise) supply voltage by 5 to 27%.
What are the main advantages of these transformers?
The major advantages are their low cost, compact size, light weight, and higher efficiency compared to equivalent isolation transformers.
Can these transformers be used as autotransformers?
Yes, they are in compliance with NEC Article 210.9, Exception 1 when field connected as an autotransformer. They can handle loads up to 20 times their nameplate rating.
What are common applications for these transformers?
They are designed for low voltage lighting circuits, control panels, and systems requiring 12, 16, 24, 32, or 48 Volts. They are also suited for low voltage landscape lighting.
Are these transformers suitable for outdoor use?
Yes, SolaHD Buck-Boost Transformers are UL Listed for outdoor service, making them suitable for low voltage landscape lighting and accent lighting applications.
What certifications do these transformers have?
They are UL Listed under UL 506 and CSA C22.2 No. 66.
What factors determine the correct transformer selection?
Key factors include input line voltage, required load voltage, load kVA or amperage, frequency (50 or 60 Hz), and number of phases (single or three phase).
Can a buck-boost transformer convert phases?
No, a buck-boost transformer cannot convert single phase to three phase. The number of phases for the line and load must match.
What frequency do these transformers operate at?
These transformers operate at either 50 or 60 Hz. The transformer's frequency must match the frequency of the load.
Where can I find fusing information?
For correct breaker or fuse sizing, refer to Section 450.4 of the National Electric Code (NEC). The selection tables also provide fuse sizes.
