SITOP PSU8600 3AC 40A PN regulated power supply. Input: 3AC 400-500 V, Output: DC 24 V/40 A with PN/IE connection. Integrated web server, integrated OPC UA server. *EX approval no longer available*. The three-phase basic units of the SITOP PSU8600 power supply system are ideally suited for use in larger plants or machines with networked (PROFINET) automation systems and high demands for reliability, functionality, and system integration. SITOP PSU8600 features two Ethernet/PFONET interfaces and a configurable output (voltage and current threshold) with selective monitoring, all within a very compact design. Without wiring effort, these power supplies can be supplemented as needed with additional modules from the system kit to expand the number of outputs or to increase the power failure bridging time. Comprehensive diagnostic and maintenance information is available via PROFINET and can be directly evaluated in the SIMATIC S7 and visualized in SIMATIC WinCC. Energy management is also optimally supported by capturing energy data for each output and the individual switching on and off of outputs via PROFIenergy. The unique modular power supply system PSU8600 with complete TIA integration sets new standards in terms of plant reliability and efficiency.
