SIEMENS 6ES7307-1KA02-0AA0 10A Regulated Power Supply – SIMATIC S7-300 Series
When a SIMATIC S7-300 rack loses its regulated DC power, the consequences cascade instantly: CPUs halt mid-cycle, I/O modules drop their process signals, and the entire production line freezes without warning. In process-critical environments—automotive assembly, chemical dosing, or water treatment—an unplanned shutdown caused by an inadequate or failed power supply can mean hours of costly downtime, scrapped batches, and safety incidents. The SIEMENS 6ES7307-1KA02-0AA0 eliminates that risk by delivering stable, regulated 24 V DC at up to 10 A directly to the S7-300 backplane, keeping every module powered and every process running.
Within the SIMATIC S7-300 power supply family, the 6ES7307-1KA02-0AA0 occupies the high-current tier, offering twice the output capacity of the 5 A variant (6ES7307-1EA01-0AA0) while sharing the same compact rail-mount form factor. Its wide-range AC input (120/230 V AC, auto-sensing) makes it the preferred choice for global OEM machine builders and system integrators who need a single SKU that ships to any plant worldwide. Since its introduction, this module has become one of the most widely deployed S7-300 power supplies in global industrial automation infrastructure.

Frequently Asked Questions
Q1: Is the 6ES7307-1KA02-0AA0 compatible with both 120 V and 230 V AC supplies?
Yes. The module features an auto-sensing wide-range input that automatically adapts to 120 V or 230 V AC (47–63 Hz) without any manual switching, making it suitable for installations worldwide.
Q2: Can this power supply run a fully populated 18-slot S7-300 rack?
In most configurations, yes. The 10 A / 240 W output provides sufficient capacity for a fully loaded UR1 rack. However, total current draw depends on the specific mix of CPU and I/O modules installed. We recommend calculating the rack’s total power budget using the SIEMENS SIMATIC S7-300 system manual before finalizing your configuration.
Q3: What is the difference between 6ES7307-1KA02-0AA0 and 6ES7307-1KA01-0AA0?
The -0AA0 suffix denotes the current hardware revision. The -1KA02 supersedes the -1KA01 with minor hardware improvements. Both are functionally equivalent and pin-compatible; the -1KA02 is the current production version recommended for new installations and replacements.
Q4: Do you supply new or refurbished units?
Konmask.com supplies both new (factory-sealed) and professionally tested used/refurbished units depending on availability. The condition is clearly stated in the quotation. All units pass our QA inspection regardless of condition.
Q5: How long does international shipping take?
Typically 3–7 business days via DHL/FedEx express, or 15–35 days via sea freight for larger orders. Lead time varies by destination country and customs clearance. We provide tracking and full shipping documentation for every shipment.
