B&R has a new power supply for seamless supply of small drives. The device can be used internationally because of its large supply voltage range of 3x 380 – 500 VAC, and it provides extensive possibilities for parameter settings and error diagnostics. Status information can be read at any time via a fieldbus connection. This allows, for example, evaluation of the load, output voltage changes or brake chopper threshold at any time. Operation close to the power limits can therefore be easily detected by the central control system. In this way, machine functionality can be ensured at all times.
Technically optimized design
The output voltage range covers 36 to 80 VDC. An additional 24 VDC output provides the possibility to supply other automation components with current requirements up to 2 A. The new power supply module is designed for continuous power output of 1 kW. The main feature of the DC power supply module is a bus interface – the output voltage can be easily configured via a fieldbus connection. A chopper output offers the possibility to connect a braking resistor for applications where large amounts of power are fed back to the power supply.
Connection to all fieldbus systems
With the large selection of B&R X20 and X67 bus controllers, it’s also possible to connect the power supply via standard fieldbus systems such as Profibus DP, ProfiNet, EtherNet/IP, CAN (with protocol-derived CANopen), DeviceNet and POWERLINK, etc. In this way, users profit from simple integration in various applications.
