latest DC Audio linear power supply (smart version) 5-20V @ 4A with overpressure protection LED display
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.
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.
The 2020 benchmark series linear power supply is designed by ZERO team for many years to design and sell the linear power supply, listening to the feedback of players and combining the actual situation;
Large current in a small volume
In the common case of zero point (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.
Low noise, low resistance and large dynamics:
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;
Low impedance: The newly designed linear voltage regulator module cooperates with Schottky rectifiers, capacitor arrays, and transformers with as much power as possible in the chassis space to further reduce the internal resistance of the power supply.
Big dynamics: Thanks to the low-impedance configuration: low-impedance linear voltage regulator module + high-power transformer + capacitor array, the power output response is extremely fast.
With over-voltage, over-current, short-circuit protection
One of the most important protection methods in linear power applications is overvoltage protection. Overvoltage is the primary cause of equipment damage. There is no one; an extra guarantee is more secure. Not to mention there are three kinds of protection
Voltage regulator
The traditional MOS tube, which still continues the zero point, has a positive effect on anti-excitation and rich harmonics.
The benchmark series linear power supply still follows the ZERO-ZONE school sound manual
"The price, performance and hearing are equally important, and the overall pursuit of harmony"
Sense of hearing
"The sound floor becomes clean, the background is black and quiet, and the detail is more clear. The high-frequency overtones are crisp, the mid-frequency is a bit more smooth and durable, and the low-frequency layering is increased. The overall tendency is neutral."
