Overview
The design and functionality of the SIPLUS PS 305 and PS 307 1-phase load power supplies (system and load current supply) with automatic range switchover of the input voltage are an optimal match for the SIMATIC S7-300 in design and functionality. By means of the connecting comb that is supplied with the system and load current supply, the supply to the CPU is quickly established. It is also possible to provide a 24 V supply to other S7-300 system components, input/output circuits of the input/output modules and, if necessary, the sensors and actuators. Comprehensive certifications, such as UL, ATEX or GL facilitate universal use (does not apply to outdoor use).
Design
- The system and load current supplies are screwed directly onto the S7-300 DIN rail and can be mounted directly to the left of the CPU (no installation clearance required)
- Diagnostics LED for indicating “Output voltage 24 V DC OK”
- ON/OFF switches (operation/stand-by) for possible swapping of modules
- Strain-relief assembly for input voltage connection cable
Function
- Connection to all 1-phase 50/60 Hz networks (120 / 230 V AC) through automatic range switching (PS307) or manual switching (PS307, outdoor)
- Short-term mains buffering
- Output voltage 24 V DC, stabilized, short-circuit-proof, open-circuit-proof
- Parallel connection of two power supplies for enhanced performance
- Ex approval for use in Zone 2 hazardous environments (gases, vapors or mists)
