Product description

The Control Techniques UNI1404 is part of the classic Unidrive series of fully digital pulse inverters. The manufacturer's operating instructions with article number 0174-0004 assign it to the size 1 and show 4.0 kVA rated device power. The associated maximum rated motor power is 2.2 kW or 3 HP; the previously visible 4.0 kW, however, belong to the next larger UNI1405. For the UNI1404, the performance table states 5.6 A rated device current. The maximum device current is 8.4 A for 60 seconds and 9.8 A for four seconds, whereby the four-second value explicitly only applies in closed loop. 9.5 A is also incorrect for this model and is assigned to the UNI1405 row. The device input current is 8.4 A in the table. The mains connection is documented with 3 AC 380 to 480 V ±10 percent and 48 to 62 Hz; the output voltage ranges from 3 AC 0 V to the respective mains voltage. For protection, Control Techniques names 10 A with fuse class gG HRC according to IEC 269. The size is self-ventilated, weighs 4 kg and is stated in this performance table as IP40. Unidrive supports V/f control, vector control with or without a speed encoder, brushless servo motor control and regenerative operation. The general data sheet states 0 to 2000 Hz in the open loop and 0 to 30,000 min⁻¹ in the closed loop. Before replacing, the complete type number, mains voltage class, motor power, control method, existing option modules, connections and parameterization must be compared; previous information on 4.0 kW, 9.0 A, 1000 Hz and the housing dimensions may not be adopted.

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.
