Schaltnetzteil 12...14V 10A Graupner 6446 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 primary pulsed switching mains PSU supplies a stabilised DC voltage at the outputs of 12 ... 14 V, at a current of up to 10 A depending on conditions. The output voltage is infinitely variable between 12 ... 14 V using a screwdriver on the underside of the unit. The default output voltage is 13.8 V. 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 weight saving compared with conventional linear mains PSUs of about 80%. Electrical units are connected using 4 mm sockets. Input voltage 230 V ± 10 % 50/60 Hz
Input power max. 160 VA
Output voltage au ralenti 12 ... 14 V ± 5 % no-load
Output current 10 A continouse, handles brief overload peaks
Efficiency typically 85 %
Protection measures IP 20
Dimensions (LxWxH) approx. 175 x 115 x 45 mm
Weight approx. 900 g
