Description

With the KNX products from Meanwell, we have included smart power supply solutions for building automation in the range.
Thanks to its slim design of only three standard units (52.2mm), the 640mA power supply KNX-20E allows space for the installation of additional components in a limited space, for example within a control cabinet. In addition to the power supply with integrated longitudinal reactor for the bus, the KNX-20E from MW MEANWELL also has a 30V output without choke, which can be used, for example, to supply another line or as auxiliary voltage for other components. The average operating time between power supply failures (MTBF) is more than 100,000 hours, determined according to the MIL-HDBK-217F standard (at 25°C). At high ambient temperatures of up to 50°C, the manufacturer gives the expected operating time of more than 30,000 hours.
