Power supply unit with internal UPS CX2100-0904

The CX2100-0904 power supply and UPS module is used for supplying power to the components (CPU modules, system and extension modules) of a CX2020 or CX2030 system. The power supply module is controlled via TwinCAT. An FSTN LC display with 2 x 16 characters and a selector switch as well as an enter key allow the querying of internal status values as well as self-created display parameters or menus with and without input options. EtherCAT or Bus Terminals can be connected on the right-hand side – the respective bus system is detected automatically and operated by the CPU. Power is supplied to the E-bus or K-bus electronics in the I/O terminals by an integrated but internally separate power supply unit with 2 A at 5 V DC. The CX2100-0904 is in principle passively cooled, has no fan and is intended for operation in the extended temperature range from -25 to +60 °C. In addition to the power supply functionality, the CX2100-0904 module also features an integrated capacitive UPS. In the event of a power failure this enables the system to save data on the storage medium and then shut down in an orderly manner.
