Active PFC 500W energy-saving Xfactor

Energy saving is the goal of today's respected low-carbon era is the development trend of the times. Xfactor from Taiwan also launched its own energy supply - Energy Pioneer Xfactor REX-500A12.

It is how to achieve energy it? Active PFC played a decisive role here, active PFC capacitor and inductor is composed of electronic components, through a dedicated IC components chip to adjust the current waveform, the phase difference between current and voltage to compensate. Active PFC can achieve power factor above 0.99. But the circuit design complexity than passive PFC, the cost is relatively high. Active PFC circuits do not have to use large-capacity power supply filter capacitor. Also active PFC also has good stability, frequency vibration, low noise.

If a product with active PFC, it means the product does not shrink to some extent, to ensure the stability of power supply, because the cost passive than active PFC PFC high. Xfactor REX-500A12 passed 3C, CE, CB certification, and many of its rated power of 500W, supporting full voltage input, and is divided into two +12 V output, the way in which the maximum output current of 24A, the maximum output of the other way current of 21A, two integrated output power of 408W, the +5 V and +3.3 V maximum output current of two, respectively 19A and 22A, two integrated output power of 130W.

Xfactor REX-500A12 entity is still using the common black surface with a nickel plated treatment, feel good in, or more, in addition to effectively prevent the surface oxidation. Power rear power plug at the outlet, with a separate power switch, you can turn off the computer, turn off the switch to achieve zero standby power consumption. Power of positive, full of diamond-shaped cooling holes, to prevent the part of the radiation exposure, but also to keep the heat inside the power supply, but also in the bottom of the access port of the switch configuration to facilitate the user alone, you can turn off the computer off switch to achieve zero standby power consumption.

Xfactor REX-500A12 power supply provides a very rich interface combinations. Interface section provides a 20 +4 pin motherboard power connector, a 4 +4 pin CPU power connectors, one 6pin graphics interface, a 6 +2 pin auxiliary power supply interface cards, four SATAII hard drive and optical drive power connector, four D type 4pin power connector and a 4pin floppy power connector.

A high-quality power supply, both to ensure power supply needs, but also to avoid frequent power outages caused by damage to the computer hardware. The Xfactor Xfactor REX-500A12 internal power supply design is very good, and the internal components of the choice of materials has also been a rigorous selection, so the overall performance of a higher power protection. In addition, active PFC power supply is more energy efficient.
