Tips: What is ripple voltage and why should we measure ripple voltage?
Ripple voltage refers to the power frequency AC voltage contained in the output DC voltage. The DC voltage should have been a fixed value, but it is often obtained by rectifying and filtering the AC voltage. Since the filtering is not thorough, there will be residual AC components. Even if it is powered by battery, ripple voltage will be produce by the fluctuation of the load. In fact, even the best reference voltage source device has ripples in its output voltage. The ripple voltage generated by the rectification will cause errors in the measured DC voltage and instability of the test power supply. Therefore, in the factory and acceptance test of DC high-voltage test equipment, the voltage ripple coefficient must be measured. According to the rules, the ripple coefficient S of DC voltage cannot be greater than 3%.

Isolated DC voltage measurement

I am looking for isolated DC voltage measurement up to 900V DC between input and output, the input supply voltage is 12V, and the output measurement signal is 0 to 12 or 0 to 5V. I noticed that you only have 24V power supply options for this type of configuration. Any suggestions?
