KNX-20E-640

Mean Well KNX power supply series KNX-20E-640

KNX switching power supplies in a DIN rail housing with 20W, a universal input, insulation class I, an LED indicator 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 are suitable for KNX applications, have a fanless design and comply with EN61558-1, EN61558-2-16, EN50491-3, EN50491-5-2, EN50491-5-3, EN61000-3-2 as well as EN61000-3-3. We offer the type KNX-20E-640 of this Mean Well series.
