Description
The PSC family of positive swiching regulators is designed
as power supply modules for electronic systems. Their ma-
jor advantages include a high level of efficiency that re-
mains virtually constant over the entire input range, high
reliability, low ripple and excellent dynamic response.
Modules with input up to 144 V are specially designed for
battery driven mobile applications.
Case C03: Aluminium, black finish and self cooling.
External input circuitry
An external capacitor (see "Application Notes") is required
in rectifier mode and in DC operation mode only, if the sum
of the lengths of the two input lines between source and in-
put (without option L) is greater than approx. 5 m. For long
connection lines the use of option L is recommended in or-
der to reduce superimposed interference voltages or cur-
rents and to prevent oscillation.
