Power Inductor Coil
A Small Transformer for Control Boards
Wenzhou Mingyue Electric Co., Ltd. has been manufacturing this power inductor coil in Liushi Town, Yueqing City for 7 years. Our plant covers 1,000 square meters and has 20 employees. We have our own R&D team. Our production complies with environmental requirements.
Before each unit leaves the factory, we test the voltage and current and inspect 100% of the products before packing. If goods are damaged during shipping, we repair or remake them. We provide a 5-year warranty. This DB-15W transformer is one of our regular products.
EI Core and Two Output Windings
This is a DB-15W EI-type low-frequency power transformer with a capacity of 15VA. The core uses EI silicon steel sheets. It has low loss and high efficiency. The input is AC220V and supports both 50Hz and 60Hz. The red wire is the input. The output uses a multi-winding structure. One winding runs from 0V red to 12V blue, and the other runs from 12V yellow to 20V green. The two windings provide AC12V and AC20V outputs and operate independently.
The winding uses pure copper enameled wire. Copper has good electrical conductivity, and the temperature rise is low. The insulation withstand voltage is AC2000V/1min. The Power Inductor Coil uses an EI silicon steel sheet core and two independent output windings.
Small Size and Easy to Install
We support OEM and ODM services. The minimum order quantity is 30 units. Different specifications can be mixed in one order. If you provide drawings, we can manufacture according to them. Custom samples can be completed within one week. Both standard and customized products can be produced within one week. Our monthly output is valued at approximately 2 million yuan.
The Power Inductor Coil uses a plug-in EI core. A metal shell protects the unit, and a mounting bracket secures it in place. Multi-color lead wires make the connections easy to identify. The working temperature ranges from -20°C to 85°C. It is mainly used in industrial control boards and instruments. It provides step-down and rectifier power supply functions. Its compact size also makes installation easier.
The Power Inductor Coil is suitable for industrial control boards and instrument power supply applications that require the specified AC12V and AC20V outputs.
