Switching Power Supply China Puno | LED stage light efficiency switching power supply

(1) switching power supply Features: 1: small size, light weight, the design is simple, because there is no frequency transformer, so size and weight was only linear power source 20 to 30% 2: low power consumption, high efficiency, power Transistors work in the off state, so small power transistor, conversion rate, generally 60 to 70% and a linear power supply only 30 to 40% (2) Switching Power Supply Applications: Widely used in switching power supply: LED display, telecommunications, communications, electricity, lighting, monitoring equipment, medical equipment, beauty equipment equipment.
