High Voltage Bias Supplies

The Model 520 Series are low noise power supplies designed for photodetector biasing applications. Output voltages up to 800V are available in two polarities. The compact size and shielded metal case make the Model 520 Series attractive for a variety of low noise biasing applications. The 523/524 versions are compact, hermetically sealed, designed for very low noise and ideal for military APD biasing applications.
