"Green Cube" M Series Circular Printed Circuit Board Welded Power Transformer

The "Green Cube" M Series ring-type fully enclosed epoxy pot-sealed power transformer includes two product lines: M and MS series. The M Series features dual input, allowing for convenient series or parallel configurations to meet different input requirements. The MS Series offers a single input for simple connection and ease of use. Both series have built-in temperature protectors for safe operation, high efficiency, minimal magnetic leakage, excellent output characteristics, strong EMC capability, compact size, and light weight. The casing is made of green flame-retardant PPO engineering plastic. These performance indicators meet the national requirements for "green, environmental protection, energy saving, and high efficiency" in the power supply industry, earning it the name "Green Cube" for its outstanding qualities.

product details

Features

① The transformers have fully-encapsulated printed circuit boards that can be directly welded and assembled, making them easy to use with a perfect outline.

② They have a compact and solid structure that is vibration-proof, moisture-proof, flame-resistant, and has high dielectric strength.

③ The transformers allow for different input and output configurations by changing the connection method.

④ They have low idle current, high power factor, good capacity to withstand over input voltage, and are strong in EMC.

⑤ A built-in temperature protector makes them safer to use.
