SIEMENS 6ES7307-1EA00-0AA0

Siemens SIMATIC S7-300 Power Supply Module Description The Siemens 6ES7 307-1EA00-0AA0, also known as the PS 307, is a robust and reliable power supply designed specifically for the SIMATIC S7-300 PLC family. It converts standard AC mains voltage into a stable 24V DC, 5A output, essential for powering the CPU and other modules within the S7-300 rack. Featuring a selectable input voltage, it offers flexibility for various industrial environments. Specifications Manufacturer: Siemens Product Series: SIMATIC S7-300 Type: Power Supply PS 307 Input Voltage: 120V / 230V AC (switch-selectable) Input Frequency: 47 to 63 Hz Output Voltage: 24V DC Output Current: 5A Mounting: S7-300 Rail Label Info Model: 6ES7 307-1EA00-0AA0 Input: AC 230V/1.3A or 120V/2.2A, 50-60Hz Output: DC 24V / 5A Max Operating Temperature: 60 deg C Application This power supply is the standard choice for small to medium-sized Siemens S7-300 automation systems used in manufacturing, process control, and building automation. It ensures a consistent power source for critical control applications. Country of Origin Made in Austria. CO2 Impact Opting for this reconditioned unit instead of a new one prevents the emission of approximately 24 kg of CO2. This saving is comparable to driving a car for 120 kilometers.

FAQ Can this PS 307 power supply be used in a redundant configuration?No, the standard 6ES7307-1EA00-0AA0 is not designed for direct parallel connection for redundancy. For redundant power supply systems in the S7-300 range, Siemens offered specific redundant power supplies and decoupling modules. What is the function of the “VOLTAGE SELECTOR” switch on the front?The voltage selector switch allows you to manually configure the power supply for different AC input voltages. You must set it to either 120V AC or 230V AC to match your local mains power before connecting it to avoid damaging the unit. Is this power supply powerful enough to supply a full S7-300 rack with multiple I/O modules?With a 5A output at 24V DC, this power supply is suitable for small to medium S7-300 configurations. However, you must always calculate the total current consumption of your specific CPU and all I/O modules on the backplane bus to ensure the 5A capacity is not exceeded. For larger systems, a 10A version or an external SITOP power supply might be necessary. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
