Product description
The Lenze EMB9342-E is a supply and regenerative feedback module from the 9300 series for multi-axis drive systems with a shared DC bus. It centrally supplies connected inverters from the three-phase mains and returns regenerative braking energy instead of converting it exclusively into heat through braking resistors. The documented mains voltage range is 320 to 528 V at 48 to 62 Hz. The module provides 14.4 kW continuous and up to 21.6 kW peak power on the DC bus. Mains-side ratings are 16.6 kVA apparent power, 24 A rated current and 36 A maximum current; the DC bus provides 26 A continuously and 39 A peak. For the connected motor group, Lenze specifies up to 12 kW shaft power in motoring operation and 17 kW in generating operation. Automatic phase-sequence detection and self-synchronisation simplify integration into existing 9300 drive systems. The EMB9342-E is a cabinet-mounted device and requires the assigned EZN3A0088H024 mains filter. The standard rail-mounted version can also be installed with a thermally separated push-through arrangement to dissipate heat outside the cabinet. Documented power loss is 200 W; above 40 °C, output must be derated by 2 percent per kelvin. Its documented weight of approximately 7.5 kg must be considered for mounting and handling. Before replacement, the complete type number, filter, mains system, DC-bus voltage, current class, cooling path, mounting method and hardware version must match. Adjacent EMB9341, EMB9343 or cold-plate versions are not unchecked direct substitutes. The module is suitable for repair, retrofit and spare-parts stocking in established Lenze 9300 drive systems that require coordinated power supply and regeneration.

The complete type number, 320–528-V mains class, EZN3A0088H024 filter, DC-bus and current ratings, mounting method, cooling and hardware version must match.
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.
