Product description

Siemens 6ES7 407-0KR00-0AA0 is the redundant-capable PS 407 10A R power-supply module for the SIMATIC S7-400 automation system. It supplies the backplane bus with up to 10 A at 5 V DC and provides an additional output of up to 1 A at 24 V DC. This 10A version is relevant where the supply to a SIMATIC-S7-400 station must be protected by redundancy or a failed module must be replaced without changing the system architecture. The documented wide-range input accepts 85 to 264 V AC and 88 to 300 V DC. It therefore covers rated values of 120/230 V AC and 110/230 V DC; the permissible frequency range is 47 to 63 Hz. Siemens explicitly identifies the PS 407 R unit as suitable for redundant operation and specifies power-failure ride-through of more than 20 ms. Indicators for internal faults, battery faults, and the 5-V and 24-V outputs support diagnostics and maintenance. Two optional lithium AA backup batteries can be installed. The module measures 50 x 290 x 217 mm and weighs 1.36 kg. Further technical data include protection class I with a protective conductor, overvoltage category II, pollution degree 2, safe isolation to IEC 61131-2 and power dissipation of 29.7 W. Before replacement, compare the complete Siemens order number, redundancy function, input range, output currents, product version, mains connection and installed battery configuration. These clearly documented electrical and mechanical characteristics support maintenance, retrofit and spare-parts stocking for the reliable restoration of a classic S7-400 station's power supply.

FAQ

Frequently asked questions

Contact us
Which voltages does Siemens 6ES7 407-0KR00-0AA0 provide?

The PS 407 10A R supplies up to 10 A at 5.1 V DC and up to 1 A at 24 V DC for the SIMATIC S7-400 system.

Is the PS 407 10A R suitable for a redundant supply?

Yes. Siemens explicitly describes 6ES7 407-0KR00-0AA0 as a redundant-capable power-supply module. Before replacement, compare the order number, product version and installed system configuration.

Is there a guarantee?

Yes, we provide a 14-day functional guarantee for used items. This means the component must be operational when received.

Please note that the guarantee only applies when the warranty seal is undamaged.

If a defect occurs within 14 calendar days, please contact us in writing. Subject to availability, we will provide a replacement or refund the full purchase price after return.

Further details are provided in the terms and conditions supplied with your quotation.

How quickly do you dispatch and which shipping options are available?

We generally dispatch immediately - in many cases on the same working day. For particularly urgent requirements or machine downtime, we find a suitable solution as quickly as possible and provide a specific delivery window on request.

Express shipping or collection from our premises is also possible, depending on the situation. State your requirements during the ordering process or contact us directly.

We ship worldwide and work with reliable shipping partners, from parcel services to freight forwarding. Freight shipments normally require some preparation so the goods arrive safely and undamaged.

Which payment methods are available?

Payment is normally made by bank transfer against invoice. Payment is due within 10 calendar days of receiving the goods.

As a rule, we offer purchase on account for all customers. In individual cases, such as new customers or particularly high-value components, we may agree advance payment. This decision is made individually and communicated transparently.

Can we return items if they were ordered incorrectly?

Because we sell exclusively to business customers (B2B), there is no general right of return and no consumer right of withdrawal.

Please note that returns of functioning goods are generally excluded. In justified exceptional cases, we can assess an individual solution, but this is not the standard procedure.

Is there a discount when ordering several items?

For larger order quantities or several items of one type, we can offer individual discounts.

Simply send us a quick enquiry - we check availability and will gladly prepare a tailored quotation with quantity pricing.

Do you also purchase industrial spare parts?

Yes, we also purchase automation components, such as frequency inverters, PLC assemblies, panels, servo motors and CPUs. Components from Siemens, Lenze, Schneider Electric, Control Techniques or Heidenhain are especially sought after, and other brands are also possible.

The process is straightforward: email us an inventory list or overview photos at info@reha-industriekomponenten.de. We calculate a market-based purchase price and send you an offer.
