The linear power supply replaces the switching power supply configured for various types of digital audio. The effects produced by it are well known to players who have used or experienced line power, and the effect is not a little improved.\u003cbr\u003e2. As the level and price of digital audio products are getting higher and higher, the lack of safety protection of traditional line power has also been significantly amplified.\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"background-color: rgb(255, 255, 0);\"\u003e\u003cb\u003eSpecification:\u003c\/b\u003e\u003c\/span\u003e\u003cbr\u003eInput voltage: AC 220V\u003cbr\u003eOutput voltage: DC 9V@4A   \u003cbr\u003e\u003cbr\u003e\u003cspan style=\"background-color: rgb(255, 255, 0);\"\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/span\u003e\u003cbr\u003e\u003cb\u003eLarge current in a small volume\u003c\/b\u003e\u003cbr\u003eIn the common case of ZEROZONE (170*250*60MM), from the early continuous 2A working current to the current 4A long stable and safe working current, this is an important breakthrough in technology.\u003cbr\u003e \u003cbr\u003e\u003cb\u003eLow noise, low resistance and large dynamics\u003c\/b\u003e\u003cbr\u003e-Low noise: within the rated operating current (within 4A), the ripple of 20Hz-20KHz (audio band) is only 1uV, and the peak value of 4.8mV is measured only at 1MHz.\u003cbr\u003e-Low impedance: the newly designed linear voltage regulator module cooperates with Schottky rectifiers, capacitor arrays 46 bits, and transformers with as much power as possible in the chassis space to further reduce the internal resistance of the power supply.\u003cbr\u003e-Big dynamics: thanks to the low-impedance configuration which is low-impedance linear voltage regulator module + high-power transformer + capacitor array, the power output response is extremely fast.\u003cbr\u003e \u003cbr\u003e\u003cb\u003eWith over-voltage, over-current, short-circuit protection\u003c\/b\u003e\u003cbr\u003eOne of the most important protection methods in linear power applications is overvoltage protection.
