<p>The circuit has input terminals (1,2) for inputting power supply voltage and output terminals (7,8) for providing output voltage. A measurement circuit determines electrical parameter based on output voltage (U) and output current (I). A short-circuit unit short-circuits input fuse, if the electrical parameter exceeds or reaches release value. A correlation circuit (6) determines correlation value of function of the output voltage and current based on the electrical parameter.</p> |
