  • Description
Product Details: 

This power board is designed with reference to the well-known Sigma22 V2.0 circuit, with a noise level as low as uV. By replacing the fine-tuning potentiometer, it can provide dual power outputs of 5V-28V, suitable for powering preamplifiers, decoders, headphone amplifiers, power amplifiers, etc.

Ultra low noise (uV level) and high PSRR.

No current limitation

Ultra-high bandwidth.

Flexible and elastic output, low internal resistance.

Positive and negative voltage automatic tracking


Specifications: 

output voltage: ±5V\±9V±10±\±12±\±15±\±18±\±24V\±27V\±30±

Size: 100mm (L) * 100mm (W)  

The voltage difference after rectification of the general input voltage should be 6-10V higher than the output voltage (calculation formula: input AC * 1.414- output DC=6-10V)

Package List: 

1 × Sigma22 power supply board
