Siemens: Powerful load current supply expands Simatic S7-1500 portfolio

Pinterest LinkedIn Tumblr

The Siemens Industry Automation Division offers the Simatic PM1507 load current supply in two versions to suit the Simatic S7-1500 controller. The two power supplies provide all the system components of the new Simatic controller, such as the CPU, the communication module and the input/output modules with 24 volts.

In addition, sensors (such as proximity switches or position encoders) and actuators (such as valves or contactors) can be provided direct with a stabilized 24-volt supply via the Simatic PM1507. Depending on the number and current requirements of the connected components, the load current supply is available in a version with 3 A of rated output current, and one with 8 A. For connecting loads with high inrush current, both power supplies provide up to 150 percent of the regular rated output current for five seconds each minute if required.

Due to its high efficiency, the new load current supply generates only low thermal losses. This means the slim modules (only 50 mm (3 A) and 75 mm (8 A)) can be mounted beside the other components on the S7-1500 system rack without gaps. Fast connection to all single-phase 120 and 230 V AC power systems is enabled by the voltage input with automatic range switchover, and the system connector. The status «power on / error / stand-by» is signaled via a three-color LED. The Simatic PM1507 is configured together with the other components of the Simatic S7-1500 via the TIA Portal.
