Product information
A reliable, robust switching mains power supply in a slim-line case, with comprehensive protective measures guarding against overload, short-circuit and reverse polarity. The overload limit is set to 8 A, which means that electrical consumer units which consume a current higher than 8 A at start-up can be operated without problem. The same applies to peak currents which arise when certain electrical consumer units are used. The adoption of a switching frequency of around 70 Hz allows the use of very small components and therefore a small case. Switching mains PSUs do not require a transformer, and this means a major weight saving compared with conventional linear mains PSUs; the unit weights 500 g, which is a reduction of about 80%. Electrical units are connected using 4 mm sockets or a car accessory socket.
