Product description
The Siemens 6SE9528-4DJ50 belongs to the MIDIMASTER Eco variable frequency drive range and is configured as ECO1-4500/3 within the series. Siemens developed these units for variable-speed control of fan and pump motors. This specific variant is designed for a three-phase input voltage of 380 to 460 V with a tolerance of ±10 %. Its rated motor power is 45 kW or 60 HP. The variant table specifies a rated output current of 84 A at 400 V and 77 A at 460 V. The enclosure is rated IP20/NEMA1 and contains a Class A EMC filter. Measuring 920 mm in height, 275 mm in width and 285 mm in depth, with a weight of 39 kg, the drive is intended for stationary installation in a control cabinet. The MIDIMASTER Eco platform provides six configurable digital inputs, two analog inputs, two configurable analog outputs and two relay outputs. An RS485 interface enables serial connectivity; setpoints can be specified digitally, via analog signals, as fixed frequencies, by motor potentiometer or through serial communication. An integrated PID controller is provided for closed-loop control. This allows the drive to process pressure, flow or other process-related setpoints within an existing plant control system. The serial interface also supports integration into a PLC or building management system, provided that the existing communication is configured appropriately. The documented overload capacity of the MIDIMASTER Eco range is 110 % for 60 seconds, while the permissible ambient temperature range is 0 to 40 °C. When sourcing a replacement, the complete order number should be compared together with the line voltage, motor power, output current, installation dimensions, filter version and existing control wiring. This enables the 6SE9528-4DJ50 to be matched precisely to an existing MIDIMASTER Eco application.

What are the power ratings of the Siemens 6SE9528-4DJ50?
The ECO1-4500/3 variant is rated for 45 kW or 60 HP and delivers 84 A at 400 V or 77 A at 460 V.
Which control and communication options does the drive provide?
The MIDIMASTER Eco supports digital and analog setpoints, fixed frequencies, a motor potentiometer, an integrated PID controller and serial communication via RS485.
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.
