Mechanical and Connection Details

The PS75 Dual Series allows the user to switch the module on and off electronically with the remote on/off feature.

The PS75 Dual Series are available with “positive logic” or “negative logic” (option).

Output Noise

The output can be trimmed externally (±5%) using a fixed resistor or a

trimpot as shown.

The output noise is measured with a 10µF tantalum and a 1.0µF

ceramic capacitor across the output.
