Summary
The PSL 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-
ules with input voltages up to 60 V are specially designed
for secondary switched and battery driven applications.
The case design allows operation at nominal load up to
50°C without additional cooling.
The modules are fitted with an H11 connector and may ei-
ther be plugged into 19" rack systems according to IEC
60297-3, or be chassis mounted.
