KNX-40E-1280

Mean Well KNX power supply series KNX-40E

KNX switching power supplies in a DIN rail housing (4SU / 72mm) with 40W, insulation class I, an LED indicator, a universal input and screw terminals (touch guard). These SELV compliant devices have an integrated choke and are protected against overload (auto recovery), overvoltage as well as short circuit. They have a fanless design, are suitable for KNX applications and comply with EN61558-1, EN61558-2-16, EN50178, EN50491-3, EN61000-3-2 as well as EN61000-3-3. We offer the type KNX-40E-1280 as well as the power supplies KNX-40E-1280D with a diagnostic function of this Mean Well series.
