Sitop PSU8600 is designed to integrate into networked automation applications and Siemens Totally Integrated Automation Portal (TIA Portal). The power supply system’s 125-mm-wide base unit provides 40 A. It is capable of providing 50% extra power for short time periods and is 94% efficient. The output current threshold can be set from 0.5 to 10 A and output voltage from 12 to 28 V. The system is also modular and expandable with additional wiring effort through the use of the built-in System Clip Link for connecting system data and supply energy. The base unit can be expanded with up to three modules for additional outputs and two buffer modules for bridging short power failures up to 600 ms. Up to 16 integrated Profinet output interfaces with selective monitoring are available with the system and may be individually set for voltage and threshold current.
