Output Noise

The PS50 series allows the user to switch the module on and off electronically with remote on/off feature. The PS50

series are available with "positive logic" or "negative logic" (option).

Output may optionally be externally trimmed (+10%) with a fixed resistor or an external trimpot as shown.

The output noise is measured with 10

μF tantalum capacitor and 1.0μF ceramic capacitor across output.
