Product description

Siemens 6ES7505-0RB00-0AB0 is a SIMATIC S7-1500 PS 60W 24/48/60V DC HF system power supply for control configurations in which the backplane bus requires a reliable operating supply and CPU data must be retained. Siemens explicitly identifies the module as a system power supply with a buffer function. The complete MLFB matters when sourcing a replacement because S7-1500 power supplies with different ratings, inputs or functions are not automatically interchangeable. The input is designed for 24, 48 or 60 V DC. Its permissible static range is 19.2 to 72 V, and the dynamic range is 18.5 to 75.5 V. Current consumption is 3 A at 24 V DC, 1.5 A at 48 V DC and 1.2 A at 60 V DC. Siemens specifies 60 W supplied to the backplane bus, 12 W of power loss, reverse-polarity protection, short-circuit protection and protection class I with a protective conductor. The documented dimensions are 105 mm wide, 147 mm high and 129 mm deep, with a weight of approximately 865 g. Before replacement, compare the S7-1500 rack configuration, CPU, available load reserve, input voltage and retention requirements. This module is especially relevant when an installed S7-1500 station must continue operating with the same buffer function and bus power as well as the same mechanical fit. The voltage, power, protection, installation and weight data provide technical purchasers with a clear basis for matching. This is a system power supply for the S7-1500 rack rather than a general-purpose load power supply. Its backplane-bus rating, input range, protective-conductor requirement, power loss and dimensions help identify the required HF version. That exact assignment supports continued use of the CPU, signal modules, distributed I/O and retention functions without changing the S7-1500 architecture.

FAQ

Frequently asked questions

Contact us
Is this Siemens product available immediately?

Yes. The item is held in stock and can be prepared for dispatch shortly after receipt of the order.

Which details should I compare before replacement?

Compare the complete order number, version, interfaces, existing engineering configuration and operating environment with the installed module.

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.
