KNX power supplies are an essential component for KNX systems. It provides constant voltage for devices in the system.
• MM1-11-640-11 is a KNX power supply with two separate outputs that can supply 30 VDC (SELV), 640mA nominal current. The primary output with integrated choke, used to supply KNX line (I1); the second is the auxiliary output (I2), which can be used to supply another devices.
• Operating status, fault status and current consumption are displayed instantly. A second KNX line can be connected via the additional output (requires additional hardware).
• The device continuously measures output voltages, currents and internal temperature. It switches off output voltages in any error cases such as short circuit, overload, reverse connection, voltage error or over temperature. It controls the line to be corrected with periodic controls. Error conditions are indicated visually by LED indicators. If the error conditions are solved, the device automatically resumes normal operation.
• The permanent type relay on the device gives information via open contact state when the mains voltage is present, and closed contact when the mains voltage is interrupted (BMS).
• The device must be installed in the electrical panel by an authorized personnel.
