Product description

The Lenze EMB9343-E is a regenerative power supply module from the 9340 series. It supplies connected drive controllers centrally through the DC bus and returns regenerative energy to the mains. This function distinguishes the unit from a braking module that dissipates regenerative energy as heat. Lenze identifies the documented variant as an E built-in unit with IP20 protection for installation in a control cabinet. The documented mains range is 3/PE AC 320–528 V at 48–62 Hz. Effective supply and regenerative power is 25.9 kW, while the stated maximum is 40.5 kW. The mains-side apparent power is 31.2 kVA, with 45 A rated mains current and 67.5 A maximum mains current. The DC-bus current is 48 A. Lenze assigns 24 kW total connected shaft power in motor operation and 30 kW in generator operation to this version. Operation is associated with an external type-A mains filter: EZN3A0055H045U for systems with UL approval or EZN3A0055H045 without UL approval. The mechanical drawing separates the individual module from the filter and mounting brackets and provides the complete housing dimensions. The rated-data table gives an exact unit weight of 13.5 kg. These dimensions and this weight refer to the individual EMB9343-E module, without the external filter, mounting clearances, cables or shipping packaging. The complete type number, electrical ratings, filter assignment and mechanical values together identify the documented variant. Documented identifiers and values: 9340; 25.9 kW; 40.5 kW; 31.2 kVA; 45 A; 67.5 A; 48 A; IP20; 320–528 V; 48–62 Hz.

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?
