Accessories for frequency converters

Accessories for frequency converters - essential system components

Frequency converters are key devices in many control systems.   They provide precise speed control of electric motors. However, inverters alone are not everything. Accessories that increase their functionality are equally important. At Onninen, we offer a wide range of complementary components.

Our offer includes, among others:

• External keyboards with 2, 3 and 5 meter cables
• Switching power supplies 30 W, 24 V DC
• Communication modules of various protocols
• Mains and motor chokes
• EMC and RFI filters

Selecting the right accessories is crucial for the optimal operation of the entire system.   Our experience shows that often small elements determine the efficiency of the system. That is why we carefully select the assortment, taking into account the needs of customers.

Keyboards and operator panels for frequency converters

One of the most important accessories are external keyboards. They allow convenient control of the inverter from a distance. Our offer includes models with cables of various lengths. The most frequently chosen are versions of 2, 3 and 5 meters.

External keyboards make it much easier to operate repeaters in hard-to-reach places.   Our experience shows that they are invaluable in many industrial applications. They allow for quick parameter changes without having to go to the control cabinet.

In addition to standard keyboards, we also offer advanced operator panels. They are equipped with LCD or touch screens. They enable full configuration and monitoring of the inverter operation. This is an ideal solution for more complex control systems.

Power supplies and communication modules for frequency converters

Another important group of accessories are power supplies. Our offer includes, among others, 30 W, 24 V DC switching power supplies. They provide stable power for control and communication systems. Their compact design allows for easy installation in control cabinets.

A properly selected power supply guarantees reliable operation of the entire control system.   In everyday practice, we see how important this is for the continuity of production processes. That is why we only offer proven and reliable models from renowned manufacturers.

Communication modules are no less important. They enable the integration of inverters with superior systems. Our range includes modules supporting popular industrial protocols:

• Profibus DP
• Modbus RTU/TCP
• CANopen
• DeviceNet
• EtherCAT

The selection of the appropriate communication module depends on the specifics of the application.   Our technical advisors will be happy to help you choose the best solution. We often come across questions about the compatibility of different protocols. We always try to advise on the best solution for a specific case.

Chokes and filters for frequency converters

Chokes and filters are an important element of frequency converter systems. They play a key role in ensuring stable and safe operation. Our offer includes both mains and motor chokes.

Mains chokes protect the inverter against interference from the mains.   In turn, motor chokes reduce the harmful effects associated with long cables. In practice, we often encounter problems resulting from the lack of these elements. That is why we always recommend their use in systems with converters.

EMC and RFI filters are equally important. They limit the emission of electromagnetic interference generated by the inverter. This is especially important in industrial environments, where many electronic devices operate. Properly selected filters ensure compliance with EMC standards.

At Onninen we offer a wide selection of chokes and filters for various inverter powers.   Our specialists will help you choose the right components. We take into account the specifics of the application and environmental requirements. This way, customers receive comprehensive and optimized solutions.

It is worth mentioning that among the brands we offer there are also our own brands. Onnline, Fxa or Opal products are a guarantee of good quality at an attractive price. They were developed with the most demanding industrial applications in mind.

Accessories for frequency converters are not just add-ons, but integral elements of the system.   Their correct selection is crucial for efficiency and reliability. At Onninen, we provide comprehensive support at every stage of the project. From component selection, through delivery, to technical support.
