Product description

Control Techniques UNI3401 is a size 3 Unidrive Classic AC frequency converter for industrial motor-control applications. The listed rating is 15kW for the documented voltage classes. The drive provides a documented 34A output rating from a three-phase industrial AC supply. Its adjustable output frequency covers the documented 0-400 output-frequency range for motor applications. The drive supports V/F operation, space-vector control, closed-loop flux-vector control and servo applications with regenerative capability. This combination allows one platform to cover pumps, fans, compressors, conveyors and suitable CNC machine drives when the installed feedback and options are compatible. Selectable switching frequencies of 3kHz, 4.5kHz and 6kHz allow motor noise and thermal loading to be balanced for the application. RS485 communication provides serial integration with higher-level control systems. For an Industry 4.0 retrofit, the serial interface and any gateway configuration must be checked separately. The IP20 enclosure is intended for installation in a protected control cabinet, and forced-air cooling dissipates the drive losses. The specified operating temperature is up to 40°C and the documented weight must be considered during installation. Before replacement, compare the complete type code, supply voltage, output current, motor-control mode, feedback, communication options, braking or regeneration arrangement and the stored parameter set. Availability should be requested before planning the maintenance window.

FAQ

Frequently asked questions

Contact us
Is there a warranty?

Yes. We provide a 14-day functional warranty for used items. The component must be functional on arrival, and the warranty applies only while the warranty seal remains undamaged. If a fault occurs within 14 calendar days, please contact us in writing. Depending on availability, we will either provide a replacement or refund the full purchase price after the item has been returned. Further details are set out in the terms and conditions supplied with our quotation.

How quickly do you ship, and which shipping options are available?

We normally dispatch available items immediately and, in many cases, on the same working day. For urgent requirements or machine downtime, we will identify the fastest suitable option and can confirm a specific delivery window on request. Express shipping and collection from our premises are also possible by arrangement. We ship worldwide using reliable parcel and freight carriers; freight shipments may require additional preparation to ensure safe delivery.

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.

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.
