1) High efficiency, low operation temperature
2) Aluminum plastic shellTransformer 220v to 12v is the product of YUEQING XIMENG ELECTRIC CO., LTD, we do have advantage in price, reliable quality, best after-sale sevrice.
Transformer 220v to 12v Principle: During the linear power, the power transistor working in the linear mode, different from the linear power, PWM power supply make the power transistor work at the conduction and off state, when being these two states, the voltammetric which add on the power transistor is very small( when it's on the conduction, the voltage is low, the current is big; When it's off-state, the voltage is high, the current is small)the voltammetric on the power parts is the loss which produced by power semiconductor parts.
Transformer 220v to 12v application: Widely used in the fields of industrial automatic control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, instruments and apparatuses, medical equipment, semiconductor refrigeration and heating, air cleaner, electronic refrigerator, liquid crystal display, audio-visual products, security, computer chassis, electronic products and instruments.
