Remote ON/OFF Control

The PS200 Series allows the user to switch the module on and off electronically with the remote on/off feature.
The PS200 Series are available with “positive logic” or “negative logic” (option).

External Output Trim

The output can be trimmed externally (±10%) using a fixed resistor or
a trimpot as shown.

All specifications typical at nominal line, full load and 25°C unless otherwise stated.

The output noise is measured with a 10µF tantalum and a 1.0µF
ceramic capacitor across the output.

Application Note

Derating:
The case operating temperature range of the PS200 series is -40°C to +100°C. When operating the PS200 series, proper derating or
cooling is required.

Following is the derating curve for the PS200 without a heatsink; airflow along width (transverse).

Where:

The power dissipated (Pd):
Pd = Pi - Po = Po (1-n) / n

The thermal resistances are listed below:
