Description: Option 1： DIY KIT without main capacitors ( KIT not include the 2pcs main capacitors.need yourself to solder it) Option 2：DIY KIT NOVER main capacitors ( KIT include 2pcs NOVER 10000uf 50V capacitors. need yourself to solder it)) Option 3: DIY KIT Nichicon main capacitors ( KIT include 2pcs Origianl Japan Nichicon 10000uf 50V capacitors. need yourself to solder it)) Option 4: Assembled board without main capacitors ( we will solder well the power supply board. but not include the 2pcs mian capacitors) Option 5: Assembled board with NOVER main capacitors ( we will solder well the power supply board. with 2pcs Nichicon main capacitors) Option 6: Assembled board with Nichicon main capacitors ( we will solder well the power supply board. with 2pcs Nichicon main capacitors) (When you choose the assembled board. Please tell us what the output you will need. then we can set it well for you before shipping ) PCB Size: 101mm*152mm PCB thickness: 1.6mm We can provide +/-5V To +/-36V all kind voltage. Generally, the voltage difference after rectification of the input voltage should be 6-10V higher than the output voltage. [Calculation formula: input AC*1.414-output DC= 6-10V] Common output voltage and recommended input voltage Output +/-5VDC transformer voltage recommend AC9V-0-9V Output +/-9VDC transformer voltage recommend AC12V-0-12V Output +/-12VDC transformer voltage recommend AC15V-0-15V Output +/-15VDC transformer voltage recommend AC18V-0-18V Output +/-18VDC transformer voltage recommend AC20V-0-20V Output +/-24VDC transformer voltage recommend AC24V-0-24V 【illustrate】: Sigma22 series voltage regulator circuit, single-digit UV level pattern index, infinitely close to the battery level; maximum support 30A current output; neutral hearing, ultra-quiet background, and high resolution. By replacing the voltage regulator tube, it can do 5V-36V dual power output, and the maximum output is 30A, which is very suitable for medium and large amps, desktop power amplifiers, and medium and high power amplifier. for high currect, need use big heatsink. 【Introduction】: Fully discrete component structure, single-stage series voltage regulator design. No ic is used, so that the whole design can control each control ring point so that the performance parameters of the voltage regulator can reach the best state. Complementary regulator structure, the negative regulator part is a complementary mirror of the positive regulator part. Ultra-low noise, extremely high PSRR (Power Ripple Rejection Ratio). The low-pass filter has a low corner frequency of 1.6Hz to prevent diode switching noise from entering the error amplifier behind, and this part also has a soft-start function. Effectively ensure that the output noise of the regulated power supply is as low as μV level. The high-current MOSFET tube ensures that the current output margin of the regulated power supply is sufficient, and the current is as high as 30A. High Bandwidth, the Sigma22 is designed to have its own bandwidth as well as well beyond the audio bandwidth. The output impedance of sigma22 is far lower than the best low-ESR large-capacity electrolytic capacitors on the market. Due to the high bandwidth design of sigma22, sigma22 can easily cope with the ever-changing current requirements of the amplifier, ensuring that the back-end amplifier can exert its maximum potential. (The output impedance is as low as μΩ, 1Ω=1000mΩ=1000000μΩ).
