MakroElectronics is your partner for professional electronics repairs.

We recently received a B&R Power Panel 300 that was no longer working. After thorough analysis, we discovered that the problem lay in worn solder joints on the processor. But don't worry, the repair was child's play for the MakroElectronics team! With our rework station, we can precisely refurbish worn solder joints and restore the devices to full functionality. 

Do you also have defective devices like this one? At MakroElectronics, we repair PLC assemblies, operator panels, programming devices, industrial PCs and drive components. A repair is usually much cheaper than a new device and is often the only solution for obsolete or discontinued components. 

Put your trust in our expertise and let us get your industrial electronics devices up and running again!

Recently, a customer asked us to check his Allen Bradley inverter, which could no longer be switched on. Naturally, we took on this problem and took a closer look at the inverter.
We could immediately see that the VDR (Voltage Dependent Resistor), which was installed to protect the DC choke of the intermediate circuit, had probably been triggered by a strong voltage spike and thus prevented the choke from burning out. Unfortunately, the voltage spike was passed through to the DC link capacitors, which were unable to absorb the overvoltage and burned out as a result. Without functioning DC link electrolytic capacitors, the voltage supply to the frequency inverter does not work and it no longer starts.

The problem could of course be solved by replacing the VDR and the electrolytic capacitors. All relevant components were then measured and a test cycle was carried out with the motor. After the repair, the customer was very pleased to receive his fully functional inverter back.

At MakroElectronics, we are here to help you solve problems like this on your industrial electronics. Do not hesitate to contact us!

The Makro team even finds solutions for unusual and unusual repair tasks: One customer had a problem with his ‘original perfecta’ Polygraph cutting machine, which was over 35 years old. The Robotron control cabinet urgently needed some repairs. The age was making itself felt: Two circuit boards were out of order and some buttons on the control unit no longer worked. But we took on the challenge and the result is speaking for itself!

Repair of circuit board A175: The output voltage was no longer available due to burnt-out conductor tracks and a defective relay. As spare parts were scarce, we quickly replaced the conductor tracks and installed a comparable replacement relay, which required some adjustments.

Repair of circuit board A160: Several components had failed and the relay contacts were contaminated. We replaced everything and repaired the relay.

Repair of keyboard: The ""0 und "1" buttons were silent and others were difficult to respond to. What was the cause? The conductive rubber buttons had lost their conductivity over time. Fortunately, we were able to find unused buttons and replace them with new ones.

In the end, we were not only able to save the cutting machine and the control cabinet, but also win back our customer's smile! Further proof that with commitment and expertise, even old technology can be restored to its former glory.

Our latest repair case: An OP 17-DP operator panel from Siemens arrived with the error message that it would not start up. After thorough analysis and the use of our thermal imaging camera, we were able to localise the problem precisely. The increased heat development was reason to a defective processor, which was also responsible for the high power consumption of the operator panel.

By replacing the processor, we were able to resolve the problem successfully. The replacement was possible without any problems as the processor did not have an internal ROM. At MakroElectronics, we repair at the component's level. Therefore, we only replace what is defective actually. This approach does not only enable a cost-efficient repair, but also ensures that your devices are ready to use as quickly as possible.

Our precise diagnosis and targeted repairs ensure that your devices function optimally. Put your trust in MakroElectronics - we'll get your technology back to peak performance!

A few weeks ago, a Yaskawa V1000 inverter arrived in our repair service center and its condition was anything but in "top form". The customer realised that something was wrong and asked for an inspection. The external condition spoke for itself: a lack of maintenance had led to creeping wear and tear. The heavy soiling created a dangerous creepage point between the connection terminal and the discharge resistors of the DC link, which ultimately led to a short circuit and the destruction of the IGBT.

After intensive cleaning and the replacement of electrolytic capacitors, ceramic resistors and the IGBT, we scrutinised the Yaskawa V1000 at our test station. All functions were successfully checked and passed the test with flying colours! The frequency inverter can now be sent back to the customer.

Remember to have your devices serviced regularly, not only to prevent breakdowns, but also to ensure their optimum performance! We are happy to service and repair industrial electronics components.

That's why we make old machines fit again:

Today we would like to tell you about an exciting project where innovation and expertise go hand in hand. A while ago, our team took on an exciting challenge: the refit of a control cabinet for a book drying system.

Why did we dare to take this step? Well, the old system was getting on in years and there were simply no spare parts left on the market. Moreover, the employees no longer have sufficient knowledge about the outdated technology. But we believe in sustainable solutions and did not want to give up on the machine!

Our main goal in this refit project was to keep the machine's proven operating concept while at the same time using the possibilities of modern technology. We designed and built the control cabinet according to the specific requirements of our customer. The automation process is carried out via a specially developed software.

The result? A book drying machine that will not only continue to function perfectly, but also offers optimised processes thanks to the new technology and software. This means not only more efficiency, but also cost savings!

We are proud to be part of this project and look forward to continuing to develop innovative solutions for our customers in the future. If you too are facing similar challenges, don't hesitate to contact us!
