Buying 6EP1437-3BA00 from Flexa Systems
Buy the Siemens 6EP1437-3BA00 power supply, in stock refurbished and available on request brand new, or send yours to Flexa Systems for repair. This unit delivers 24 VDC at up to 40 A for a 960W output. That capacity typically anchors the DC rail of a large control cabinet, feeding PLC racks, distributed I/O, sensors, solenoid valves and relay coils from a single source. Before ordering, add up the current drawn by every load on that 24 VDC rail to confirm the 40 A rating still leaves headroom after any panel changes made since the original install. Every refurbished 6EP1437-3BA00 is tested before it ships, carries a 2-year warranty and costs 30-60% less than a brand new unit.
Repair option: send in your faulty unit for component-level repair — $370.00 with free diagnostics, a 2-year warranty, and a 5–30 business day turnaround. Repair typically costs 40–70% of a new unit, saving you 30–60%. Learn more about our Siemens repair and industrial circuit board repair.

6EP1437-3BA00 FAQ
What should I match before swapping in a 6EP1437-3BA00?
Check the rating plate on your installed unit. The output should read 24 VDC, 40 A and 960W. Also confirm that the input listed on the plate matches your cabinet feed, and that the mounting space and terminal wiring line up with the existing installation.
Should I buy a refurbished or brand new 6EP1437-3BA00?
A refurbished unit is in stock and provides the same 24 VDC, 40 A output at a lower cost. Brand new is available on request if your plant standard calls for unused parts.
