High end dual DC output linear power supply.
The core solution is developed to meet the needs of high-definition audio and video devices, with low ripple, high speed, and low internal resistance characteristics. The voltage includes multiple versions of DC5V, 9V, 12V, 15V, 19V, and 24V. Circuit architecture precision voltage reference+OPA1611 high-speed operational amplifier+UV level noise DC stabilized circuit with high-power transistor; At the same time, the circuit has added a CLC high current fever filtering inductor, and the EMI isolation stage further improves the quality of the DC power supply!
Note that this belongs to a linear power supply, not a switching power supply. There must be a certain temperature when outputting 4-5A, but it is completely within the normal safety range.
The overall weight is about 3KG,
Host size: 25cmX16cmX6cm,
All aluminum alloy chassis, output can be customized according to customer requirements, such as 5V, 7V, 9V, 12V, 15V, 24V, etc., with a maximum current of 8A. However, due to the high current, there is a certain temperature when the load power is high, which is different from switching power supplies, but it is also normal.
Accessories:
2X DC output lines, default 5.5-2.5mm interface.
Batch customizable output interfaces, output lines, etc.
Note: The components on the board may be adjusted to other brands and parameters of the same grade as needed, and the actual product shall prevail without further notice. Please do not consider this as cutting corners.
Using high current Toshiba tube 2SC5200 to drive output with sufficiently low internal resistance, handling high current output effortlessly and effortlessly.
A core with no breakpoints, iron core with oxygen free copper enameled wire, lower noise, and very quiet background and level.
The CLC circuit adopts a red ring inductor and four Nikon filtering capacitors to eliminate high-frequency noise and fluctuations in the circuit, thereby improving the stability and accuracy of the circuit.
25A high current rectifier bridge+array filtering capacitor
Using 9 Japanese original Nikon Nichicon filtering capacitors, it has low impedance, high ripple, and long lifespan
High temperature resistance and other characteristics make it particularly suitable for electronic circuits that require high performance and stability.
Precision benchmark+high-speed operational amplifier
The operational amplifier adopts high-end American OPA1611 with ultra-low distortion (0.000015%),
The benchmark is set with a constant current diode, and the noise is very low.
