The stabilized power supplies SITOP compact with 12 V and 24 V have an extremely slimline design (22.5 to 30 mm) that marks them out for distributed applications, e.g. in control boxes. They are characterized by their low power loss over the entire load range and low energy consumption during no-load or standby. The wide-range input enables connection to AC and DC networks. The plug-in terminals also ensure user-friendly connection.
