NOTE

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25oCof ambient temperature.

2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.

3. Tolerance : includes set up tolerance, line regulation and load regulation.

4. Line regulation is measured from low line to high line at rated load.

5. Load regulation is measured from 20% to 100% rated load, and other output at 60% rated load.

6. Each output can work within current range. But total output power can not exceed rated output power.

7. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives.

What is a switching power supply?

Switching power supply is the use of modern power electronic technology, control switch tube opened and shut off time ratio, to maintain stable output voltage of a power supply, switching power supply by general pulse width modulation (PWM) control IC and MOSFET.

What is the application scope of switch power supply?

Switching power supply products are widely used in industrial automation control, military industry equipment, scientific research equipment, LED lighting, industrial control equipment, communications equipment, electrical equipment, instrumentation, medical equipment, semiconductor refrigeration and heating, air purifier, electronic refrigerator, LCD, LED lamps and lanterns, communications equipment, audio and video products, security monitoring, leds bags, computer case, digital products and instruments, etc.

What is the structure of switch power supply products?

Roughly by the main switch power supply circuit, control circuit, detection circuit, auxiliary power supply of the four most.

Switching Power Supply Common faults:

1.Blown fuse.
2.No dc voltage output or the output voltage is not stable.
3.The power load ability is poor.

MingWei switching power supply factory is a set design, development, production in one of the high-tech professional manufacturers, the region is the first company to introduce Taiwan manufacturer of switch power supply technology, building in May 2001.
