The circuit, based on the integrated CS5530 Cirrus Logic has very few components. An additional condition a circuit allows input voltage to 400V to deliver 0-10V output, which shall be that read the chip.
Retirar los puentes entre ANR y AIN.
Conectar la la fuente a medir (max. 400V DC) en AN10V, respetando la polaridad.
Ajustar, mediante un comprobador, el voltaje en ANR que no debe de ser superior a 10V.
Colocar los puentes entre ANR y AIN.
Alimentar el circuito a través de AIN5V.
*El voltaje indicado por el display se habrá de multiplicar por x, siendo x = AN10V / ANR
Operation mode.
Remove the bridges between ANR and AIN.
Connect the source to measure (max. 400V DC) in AN10V, respecting the polarity.
Adjusted by a tester, the voltage on ANR must not exceed 10V.
Put the jumpers between ANR and AIN.
Circuit feed through AIN5V.
*The voltage indicated on the display is to be multiplied by x, where x = AN10V / ANR
