Application Note
Derating:
The operating case temperature range of the PS100 series is -40°C to +100°C. When operating the PS100 series,
proper derating or cooling is needed.
The following curve is the derating curve of a PS100 without heat sink.

Remote ON/OFF Control
The PS100 series allows the user to switch the module on and off electronically with remote on/off feature. The PS100
series are available with "positive logic" or "negative logic" (option).
External Output Trimming
Output may optionally be externally trimmed (+10%) with a fixed resistor or an external trimpot as shown.
Output Noise
The output noise is measur
ed with 10
µF tantalum capacitor and 1.0µF ceramic capacitor acr
oss output.
