-Benefits

The design and functionality of the SIMATIC PS 307 single-phase load power supply (system and load current supply) with automatic range switchover of the input voltage is an optimal match to the SIMATIC S7-300 PLC.
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 24V 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).
The system and load current supplies are screwed directly onto the S7-300 standard mounting rail and can be mounted directly to the left of the CPU (no installation clearance required)
Diagnostic LED for indicating "Output voltage 24Vdc OK"
ON/OFF switches (operation/standby) for possible swapping of modules
Strain-relief assembly for input voltage connection cable
Connection to all 1-phase 50/60 Hz networks (120 / 230Vac) through automatic range switching (PS307) or manual switching (PS307; outdoor)
Short-term power failure backup
Output voltage 24Vdc; stabilized; short circuit-proof; open circuit-proof
Parallel connection of two power supplies for enhanced performance
