Sigma22 Regulated Power Supply Board For Beta 22 β22 Amp DIY +/-5V To +/-36V NOVER 10000uf 50V Capacitance

Product Description

PCB Size: 101mm*152mm
PCB thickness: 1.6mm

The two mian filter capacitors are 2pcs NOVER 10000uf 50V capacitors.
We also can provide Other voltage. +/-5V To +/-36V all kind voltages. If you need other voltage. Please contact us. thanks!

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]

About cooling:
The standard heat sink of the board can withstand a power consumption of nearly 1 watt (2 Parallel transistor heatsink 2W in total), which can be estimated according to PT=V*I. When the heat generation is too large, it is recommended to use the chassis bottom plate to dissipate heat.

The board default heatsink only suitable for preamp/DAC/headphone amp etc some small currect device. for large current use such as power amp. recommned use the Chassis bottom plate cooling.

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).

NOTE: We have DIY kit or finished board(Optional)

◆ DIY kit ---- Include all parts. It needs to be welded by yourself.

◆ Finished board ---- We will solder and test it well before shipping.
