300VA Single‑Phase Dry‑type Rectifier Transformer

300VA Single‑Phase Dry‑type Rectifier Transformer

Capacity and input/output voltage can be customized.

300VA single-phase dry-type rectifier transformer is designed to convert AC input to power suitable for downstream DC rectifier circuits. It features a robust dry-type construction, reliable performance, safe operation, easy field installation, and low daily maintenance costs. It is widely used in various rectification-centric applications: battery charging equipment, battery charger power supplies, electroplating power supplies, small-capacity electrolysis systems, DC motor excitation, industrial DC control circuits, and other DC-DC conversion equipment. Available in both copper and aluminum winding versions, you can choose the appropriate solution based on your project budget and technical requirements. Transformer capacity, input, and output voltage are fully customizable to meet different site specifications.
