Power supplies for the efficient, flexible use of distributed controllers
The picutre shows the Simatic ET 200SP PS 24 V, 5 Adistributed I/O system.
The output voltage is adjustable up to 28 V in order to compensate for voltage drops on long lines. The extremely flat design and low heat development of the power supplies allow space-saving mounting in distribution boards. They also have an extended ambient temperature range from -30 to +70 °C and an efficiency of up to 90%, which keeps heat development down. On account of the automatic switchover of the input voltage (85-132/170-264 V AC) and comprehensive certifications, the power supplies can be used all over the world. Large power reserves of 1.5 times the rated current for "extra power" for 5 s/min ensure trouble-free switching of loads with a high inrush current and reliable operation. The on/off switch for the 24 volts allows the floating exchange of the distributed I/O modules. Plug-in terminals allow three separate load circuits to be disconnected and so simplify commissioning and maintenance of the system. The current monitor outputs the present output current as a voltage value, and can be wired to an analog input. In this case, 1 V corresponds to the rated current of the power supply, that is 5 A or 10 A. The measurement allows users not only to diagnose the load current at any time and detect faults through an increased current requirement, but also to optimize the energy management.
