The unique SITOP PSU8600 power supply system sets new standards for industrial power supplies. Voltage and current response thresholds can be set individually for each output of this power supply system. Selective monitoring of each output for overload also enables fast fault location. Depending on requirements, additional modules from the modular system can be added without wiring overhead, for example, to buffer against transient power failures.

Comprehensive diagnostic and maintenance information is available via PROFINET and can be evaluated and visualized directly in SIMATIC PCS 7. Optimal support is also provided for energy management of a plant: From the acquisition of energy data from individual outputs, the specific activation and deactivation of outputs via PROFIenergy, to direct integration in power management systems.

Special features

• Reduced space requirement and costs due to multiple integrated outputs with selective monitoring
• Individually configurable outputs (voltage from 5В V to 28В V, power response threshold value from 0.5В A to 5В A or 10В A)
• Compensation for power losses can be set separately for each output
• Narrow width without lateral installation clearances
• Low temperature rise in the control cabinet due to very high efficiency
• Two integrated Ethernet/PROFINET ports (no external switch required)
• OPC UA Server functionality for parameter assignment and data communication
• Can be added without wiring overhead (more outputs, buffer module for bridging transient power failures)
• Preventive maintenance reduces downtimes
• Energy savings during breaks through targeted switching of outputs (via STEPВ 7 program or PROFIenergy profile)
• SIMATIC S7 function blocks for easy integration in STEPВ 7 user programs and faceplates for operator control and monitoring.
• Direct integration in SIMATIC PCSВ 7 via SITOP library
