Summary
The PSA series of positive switching regulators is de-
signed as power supply modules for electronic systems.
Their major advantages include a high level of efficiency
that remains virtually constant over the entire input range,
high reliability, low ripple and excellent dynamic response.
Safety according to IEC/EN 60950
Modules with input voltages up to 144 V are specially de-
signed for battery-driven mobile applications. The case
design allows operation at nominal load up to 71 °C with-
out additional cooling.
Non standard input/output configurations or special custom adaptions are available on request.
