Remote ON/OFF Control

External Output Trimming

Output Noise

The PS50W Series allows the user to switch the module on and off electronically with remote on/off feature.

The PS50W Series are available in "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 measur

ed with 10

µF tantalum capacitor and 1.0µF ceramic capacitor acr

oss output.
