ELSNER 70147 KNX PS640-IP 2U Intelligent Power Supply KNX bus/Auxiliary Voltage

KNX PS640-IP 2U Intelligent Power Supply KNX bus/Auxiliary Voltage

• 640 mA KNX power supply unit requires less space, having only 2 units (36 mm)
• Device reset by on-device push button
• Monitoring of device data, events and output failures
• Configurable additional alarms

The intelligent Power Supply KNX PS640-IP 2U with extensive diagnostic and alarm functionality powers one line of a KNX system with 30 V DC and has an additional unchoked voltage output to provide auxiliary power. Both outputs are overload-proof and short circuit protected. LEDs indicate the state of the power supply and the KNX TP line. The KNX TP line can be reset via object and via push-button press. For diagnostics, input state, KNX bus voltage, output current, device temperature and times of operation (total/since last startup) are monitored. Alarms inform about measurement values leaving the normal working range or the configured threshold range. Up to eight different alarms can be pre-defined.

KNX PS640-IP 2U is able to send info telegrams on request, periodically and after certain events. Details (number/duration) on output failures like short circuits, overloads and over-threshold events are accessible. Info telegrams also inform on returning to normal working condition after device startup, after a NX bus restart and after a short circuit. Heartbeat telegrams indicate proper functioning
