A guide to transformer selection

Version 2026 | Reference for Isolated Drive Power Transformers

Selection Guide

8–12 W isolated driver – Watt’s recommended EE1340 series, which is widely used in recessed lights, spotlights, cabinet lights, and commercial lighting products, among others.

· The solution is well‑developed and reduces the need for repeated trial‑and‑error.

· EMCThis stability makes it easier for the project to pass testing.

· The costs are lower, making this approach ideal for both new project development and cost reduction in existing projects.

30–40 W isolated driver – Watt’s recommended EQ23 series, ideal for use with panel lights, linear lights, grid lights , classroom lighting, and office lighting. Such scenarios.

· It offers excellent value for money and is well‑suited for large‑scale applications.

· Long‑term reliability means project delivery is more dependable.

· We will develop a mature solution tailored to 30–40 W application scenarios.

The Watt Programme

Instead of simply building an inductive transformer, Watt looked at power‑application scenarios and helped its customers take efficiency, temperature rise, EMC, cost, and delivery stability into account all at once.

Therefore, in 2026, 8-12 W, 30-40W isolation drive transformer selection, without repeated trial and error.

This brings not "the individual transformer is a little cheaper," but the overall scheme cost is easier to achieve, project entry is cheaper, and production delivery is more stable.

· A mature platform that minimizes repeated trial‑and‑error.

· The cost advantage is not limited to unit price alone.

· Its performance is stable, which makes it easier to conduct EMC and temperature‑rise testing.

· High‑volume delivery capability – ideal for long‑term projects.
