The AX 500 laboratory power supply series are robust, economical and reliable power supplies with low weight and are thus ideally suited for laboratory use. Thanks to linear technology, these work in a stable and largely noise-free manner. They offer protection against short-circuits, overloads and overheating through electronic current limitation and built-in temperature monitoring. The built-in toroidal transformers have a high degree of efficiency, which means no forced ventilation is required and low radiation is present. The security booking offers double protection by double insulation.The AX 503 with 3 outputs is available in two versions:AX 503 version: Output 3 with 3 and 5 VDC (2.7 to 5.5 VDC) and 0 to 5 A.AX 503F version: Output 3 fixed at 3.3 VDC and 5 A.This text is machine translated.
