Ordering Instructions
When the customer orders, they must provide the following information:
- The product model and window width;
- Rated current ratio;
- Rated output, and the corresponding accurate level;
- For example: order LMK3 (BH) – 0.66 type, window width is 80 mm, rated current than 1500/5 A, and rated output is 10 VA, accurate magnitude of 0.5 on the Richter scale transformer. Orders, code-named LMK3 (BH) 0.66 Φ 80 1500/5 1 turn 10 VA a 0.5 on the Richter scale are unlikely.
If you have special requirements, a customized consultation with the manufacturer.
