Industrial automation technology requires a stable power supply. In the event of a temporary overload or short circuit, the power supplies shut down or significantly reduce the output current, following which the loads in the circuit are insufficiently supplied, which can result in unwanted production downtime.

With the SITOP PSE200U selectivity module – 6EP1961-2BA21 , overloads or short circuits are easily and effectively prevented. The task of the power supply is to distribute the load current to several circuits and monitor them for signs of overload and short circuit. The PSE200U has 4 outputs with a voltage measurement point for current (1 V ≙ 1 A).

SITOP’s selectivity and diagnostic modules have become an optimal extension for 24-VDC power supplies. Overloads and short circuits in the circuit are recognized, and the faulty load circuit is effectively disconnected, while other efficient circuits continue to operate without any interruption, in a proven way to prevent the failure of a major part of the installation. Reliable operation, regardless of cable length or cross section, 4 to 8 24 V DC power supplies per module, Alternative shutdown characteristics: Limiting – prevents a brief voltage drop below 20 V, Switching – can cause a brief voltage drop below 20 V.

Due to their reliability, SITOP systems are used worldwide in critical network environments. No matter the business sector, no matter the need, a stable power supply is essential for efficient plant operation. SITOP was designed specifically for tasks in this field and has been the first choice for decades, setting the standard for integration, performance and reliability.

Performance for the SITOP system starts with a simple selection of devices in the TIA Selection Tool or engineering data for CAE or SIMATIC PCS 7 systems. Compact, efficient thermally optimized design saves necessary space during installation. With flexible inputs with a wide range, stable load maintenance and appropriate certifications, the SITOP series power supplies ensure maximum installation reliability. In addition, with uninterruptible DC power supplies, they can guarantee the safety of the system in case of power failures or additional modules against overloads or short circuits in the circuit. It is also possible to install a redundant power supply.
