SANHE-EE19-002 is a small power transfomer mainly for lighting products. It can provide basic working voltage for power supplies of lighting. Because the interior space of lamps and lanterns is usually relatively tight, this transformer is designed with a small structure to adjust the interior strcture of lighting products and to ensure that it can be well fit in. Besides, it is optimized considering poor heat dissipation environment and limited EMC components of lighting. It is a cost-effective switching power transformer.

1. Due to the structural design of lengthened secondary side, there' s no need for additional insulation measures
2. The secondary side uses triple insulated copper wire to meet the standard of reinforced insulation
3. Use copper foil for EMC shielding to reduce radiation


1. Small size, more convenient to install
2. Sufficient temperature rise margin
3. Good EMC anti-interference
4. Suitable for automatic winding, reduces labor cost
5. Generally used structure has the possibility to expand more models with different specifications based on this transformer
