The longer the cable, the smaller the cross-section and the higher the current, the greater it is.<\/p>\n\n\n<h2 class=\"wp-block-heading\">Why does this matter at 24 V?<\/h2>\n\n\n<p class=\"wp-block-paragraph\">At 24 V, losing just a few volts is a large share. If too little voltage reaches the actuator, it runs slower, lacks force or stops. A voltage drop of at most about 5 %, i.e. around 1.2 V, is usual.<\/p>\n\n\n<h2 class=\"wp-block-heading\">Formula<\/h2>\n\n\n<p class=\"wp-block-paragraph\">Voltage drop \u2248 2 \u00d7 length \u00d7 current \u00f7 (56 \u00d7 cross-section). 56 is the conductivity of copper in m\/(\u03a9\u00b7mm\u00b2).<\/p>\n\n\n<p class=\"wp-block-paragraph\">Example: 20 m of cable, 2 A and 1.5 mm\u00b2 result in a voltage drop of around 0.95 V.<\/p>\n\n\n<p class=\"wp-block-paragraph\">Learn more: <a href=\"\/en\/dictionary\/cable-cross-section\/\">Cable cross-section with table<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Der Spannungsfall ist der Teil der Spannung, der auf einer Leitung verloren geht.
