Summary
The PSB series of positive switching 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. Mod-
Safety according to IEC/EN 60950
ules with input voltages up to 80 V are specially designed
for secondary switched and battery driven applications. The
case design allows operation at nominal load up to 71°C
without additional cooling.
Non standard input/output configurations or special custom adaptions are available on request.
