Product description

The Siemens 6SE7028-6EC85-1AA0 combines supply and regenerative feedback functions in a compact unit. It belongs to SIMOVERT MASTERDRIVES and is supplied with three-phase alternating voltage on the mains side. The voltage range extends from 380 to 480 V at a mains frequency of 50 or 60 Hz. Input current and DC-link current must be considered separately for electrical sizing. Input current is 74 A. On the DC side, the rated current is 86 A; a base-load current of 78 A and a short-time current of 117 A are also specified. The short-time value does not describe an additional continuous operating point. The selection values refer to a mains inductance of 3 % relative to the unit impedance. The power allocation of 37 kW serves as a guideline for selecting further components. The actual drive power depends on the connected inverters and must be taken into account during engineering. A dead time of 15 ms must be allowed when switching rapidly between supply and regenerative feedback. Supply and regenerative operation therefore represent different operating phases of the same unit. For thermal planning, total losses are 0.31 kW and the required cooling airflow is 0.028 m³/s. The compact unit has an IP20 protection rating. In the quotation for this supply/regenerative feedback unit, shipping from Germany to the United States and other international destinations is arranged for the specific order. Mechanically, the unit requires 180 mm in width, 600 mm in height and 350 mm in depth. These external dimensions describe the unit itself; additional installation clearances must be considered separately during system planning. Net weight is 22 kg.

FAQ

Frequently asked questions

Contact us
What mains supply does this supply/regenerative feedback unit require?

This version operates on 3 AC 380–480 V at 50/60 Hz.

How do input current and DC-link current differ?

Input current is 74 A. Rated DC-link current is 86 A, base-load current is 78 A and short-time current is 117 A.

What applies if an item develops a defect within 14 days?

For the condition categories “Used, removed from an installation” and “New, old stock”, the contractual 14-day right of return in the event of a defect applies. The defect must occur within 14 calendar days after delivery and be reported in text form within the same period.

In particular, the REHA tamper-evident seal must remain fully intact and our RMA approval is required before return. In an accepted case, we decide between replacement and refund. Details in Section 11 of the Terms.

Which shipping methods and delivery times are available?

The shipping method, shipping cost and estimated delivery time are confirmed for the specific order. Depending on the item, destination and urgency, we can check parcel, express or freight shipping as well as collection.

A delivery date is binding only if we expressly confirm it as binding.

Which payment terms apply?

The payment terms stated in the checkout or order confirmation apply. Depending on the order and customer, payment is made in advance or against invoice.

International deliveries and deliveries to new customers are generally made against advance payment unless we expressly confirm another payment arrangement.

Can I return an item ordered incorrectly or found incompatible?

No. There is no general B2B right of return, exchange, cancellation or withdrawal. Incorrect or duplicate orders and a lack of suitability or compatibility with the customer’s installation are not covered by the contractual 14-day right of return in the event of a defect. Details in Section 12 of the Terms.

Can I request individual pricing for several items?

You may request an individual quotation for several items or larger quantities. We then check availability and pricing for the specific requirement; there is no entitlement to a quantity discount. Open the quick enquiry.

Do you also purchase industrial spare parts?

Yes. You can offer us automation and drive components for purchase. Please provide complete type numbers, quantities, condition details and photographs where possible.

After review, we will tell you whether a purchase is possible and on which terms. Learn more about selling industrial stock.
