Elsner KNX PS640+ KNX power supply

The KNX PS640+ power supply provides 29 V bus voltage for the KNX system and 24 V DC supply voltage for 24 V devices. Special operating states such as short circuit, overvoltage, overload or overtemperature are logged and can be read on the display. The current current consumption is also shown. The connected bus devices can be reset directly via the keypad. In addition, all functions can also be implemented via the bus, e.g. the transmission of error messages and operating data and a time/duration reset. Error messages are stored by the KNX PS640+.
