Power Supply with Diagnostics, 640mA, MDRC
ABB SV/S30.640.5.1

Power Supply with Diagnostics, 640mA, MDRC

Product code: SV/S30.640.5.1
KNX power supplies generate and monitor the KNX system voltage (SELV). The bus line is decoupled from the power supply by an integrated choke. Bus current, bus voltage, overload and other messages can be sent via KNX for monitoring and diagnostic purposes.
Price (Excluding GST)


The Power Supplies SV/S 30.x.y.1 are equipped with an advanced LED display indicating the current bus load and offering a rapid diagnosis of the bus state. The state values are also provided via communication objects to the KNX system. Additionally, the ABB i-bus Tool enables a detailed analysis of actual values. The connection to the KNX is established via a bus connection terminal. All other connections are made via 6 mm terminals equipped with a universal head screw.

The device is equipped with an additional output without choke.

Benefits and Advantages
- Rapid and enhanced diagnostics via LED display and ABB i-bus Tool
- State values of the power supply also available via bus communication objects
- Wide-range voltage input from 85 to 265 V AC at 50/60 Hz for worldwide usage

- Providing the KNX system voltage (SELV)
- Power supply of KNX devices
- Diagnosis of device state, bus line and communication
- Monitoring of KNX installations
