When operating the PS50 series, proper derating or cooling is needed. The following curve is the derating curve of a PS50 without heat sink. Where: The power dissipation (Pd): Pd = Pi - Po = Po (1-n) /n The thermal resistance are listed below: Chart of Thermal Resistance vs Air Flow: The temperature rise ( T ): T = Pd * Rca Application Note AIR FLOW RATE TYPICAL Rca Natural Convection 20ft./min.

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.
