UL Certified Small Size EFD30 Stable Switch Mode Power Supply Transformer For Rice Cookers

Short Description:

Model NO. :SANHE-EFD30-002

It is a switch mode power supply transformer used in rice cookers, which provides the required voltage for the power supply part of the rice cooker, so that the microprocessor can send required signals. It can also supply power for each functional module of the rice cooker, to achieve heating, keeping warm, timing and other functions.The transformer adopts EFD30 small structure and is designed with flyback principle, which can provide four groups of required working voltages at the same time.

PFC Inductor (3)


The main function is to supply power to the rice cooker, and cooperate with the relevant circuit to supply power to the control module to achieve various specified functions. When the rice cooker starts to work, the AC 220V mains power will go through the transformer to achieve the DC voltage stabilizing circuit. The transformer will output DC voltage power to the microprocessor, the relay circuit and the switch tube circuit and monitor the working status, such as temperature, water volume, etc.,to adjust them timely.

1. In order to adapt to the internal space of the product, the transformer adopts a flat-shaped EFD structure with a low height
2. Flyback circuit design is more simple and cost-effective to cope with small power
3. Combination of series-parallel ensures good coupling, so that the multiple output voltage can maintain a stable state under different load conditions


1. Small size, mature structure and production process, and stable quality
2. Considering the need for multiple output, its cross regulation design realizes the accuracy of voltage output in different operating conditions.
3.Low loss, high efficiency, no noise interference, sufficient insulation design, and good safety features.
