Product description

The Siemens 6SE9523-0DG50 is a MIDIMASTER Eco frequency converter with the device designation ECO1-1500/3. It was designed for variable-speed drives on three-phase 380- to 460-V supplies and belongs to the control-cabinet-oriented IP20-/NEMA1 version. An integrated Class A RFI filter forms part of this variant. The unit can therefore be distinguished clearly from other MIDIMASTER versions by its complete order number, Eco frame size, supply range and filter configuration. Siemens specifies an input-voltage range from 380 to 460 V with ±10 % tolerance. The assigned motor rating is 15 kW or 20 HP. Rated output current is 30 A at 400 V and 27 A at 460 V. The enclosure measures 700 x 275 x 210 mm and weighs approximately 19 kg. These values are particularly important because adjacent Eco power ratings use different output currents, dimensions and order numbers despite belonging to the same device family. For replacement, the complete MLFB and power rating must therefore be checked together. Before installation, the supply voltage, motor rating data, existing wiring, protection concept, cabinet ventilation and parameterisation should be compared with the previous converter. The integrated filter and mechanical installation dimensions must also match the installed system. Comparing both output-current values is useful when the machine operates at a supply voltage other than 400 V. The 6SE9523-0DG50 is suitable as a targeted replacement for existing MIDIMASTER Eco applications when the ECO1-1500/3 version, 15-kW rating and electrical configuration match the machine. The documented data support a safe variant comparison during maintenance, repair or a planned retrofit of legacy drive systems.

What is the rating of the Siemens 6SE9523-0DG50?

The ECO1-1500/3 variant is rated for a 15 kW or 20 HP motor. Rated output current is 30 A at 400 V and 27 A at 460 V.

Does the 6SE9523-0DG50 include an RFI filter?

Yes. Siemens lists the IP20-/NEMA1 version with an integrated Class A RFI filter.

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.
