The three-phase basic units of the SITOP PSU8600 power supply system accommodate within their extremely compact width an Ethernet/PROFINET interface as well as four individually parameterizable outputs (voltage and current threshold) with selective monitoring.
Without wiring overhead; further modules from the modular system can be added to expand the number of outputs (CNX8600); to increase the mains buffering time (BUF8600); or to buffer longer power failures (UPS8600 with BAT8600) according to requirements.
Comprehensive diagnostic and maintenance information is available via PROFINET. It can be evaluated directly in SIMATIC S7 and visualized in SIMATIC WinCC.
Energy management is also optimally supported by collecting the energy data for each output as well as individual activation and deactivation of the outputs via PROFIenergy.
The integrated OPC UA server also allows direct integration into automation applications with OPC UA clients made by different manufacturers; e.g. of controllers or PCs. Not only the parameter assignment but also the diagnostics of the power supply system are possible via the open interface.
Three-phase wide-range input 400 to 500V 3 AC for global use
Extremely slim design with very high efficiency of up to 94%
Versions with a configurable output with up to 20A or 40A and selective monitoring.
Versions with four integrated; individually configured outputs with up to 5A or 10A each and selective monitoring
Voltage and response threshold can be set separately and are infinitely adjustable for each output
Extra power with 1.5 times the rated current (5 s/min) for brief functional overload
Integrated Ethernet/PROFINET interface (2 ports)
Easy configuration in the TIA Portal
Comprehensive diagnostic information during operation
Outputs can be deactivated and activated selectively via PROFIenergy
Individual expansion options from the modular system (CNX8600 expansion modules; BUF8600 buffer modules; or UPS8600 with BAT8600 for buffering longer power failures) without wiring overhead
