Invertek Optidrive E4: The Right Information for Faster Fault Diagnosis
Fast fault diagnosis starts with the right information.
Variable frequency drives now do far more than simply control motor speed.
With the Optidrive E4, Invertek Drives offers additional functions that are particularly relevant to commissioning, integration and fault diagnosis. These include enhanced diagnostic capabilities and industrial communication interfaces.
Such functions can help users understand operating conditions and identify the causes of faults more quickly.
The purchase price of a variable frequency drive is not the only factor that matters. The effort required for commissioning, operation and maintenance is also important.
As a technical distributor, we support our customers in selecting suitable drive solutions.

Hongfa HFE85P-250: Switching Direct Current Safely
Switching direct current safely is a particular challenge.
As energy storage systems become more widespread, demands on switching technology are increasing. Unlike alternating current, direct current has no regular natural zero crossing. This makes controlling the arc during switch-off particularly demanding.
Hongfa offers dedicated high-voltage DC relays for this purpose. The HFE85P-250 uses a hermetic ceramic seal and a gas filling.
Selection depends not only on rated voltage and continuous current, but especially on the actual switching and breaking conditions of the application.
As a technical distributor, we support our customers in selecting suitable switching components.

DEGSON 9EDGCP: Connection Technology Suited to the Manufacturing Process
Connection technology also needs to suit the manufacturing process.
When selecting industrial connectors, electrical characteristics, size and price are often the main focus. How a connection is made during manufacturing and maintained later is just as important.
The DEGSON 9EDGCP series uses crimp contacts and pluggable connections. Different pitches and mounting options provide possibilities for standardised, pre-assembled cable harnesses.
In repetitive manufacturing processes, such solutions can simplify assembly and the replacement of modules. Correct design and professional processing remain essential.
For us, this is a good example of why connection technology should always be considered in the context of the entire application.

KAMMRELAIS® from the EBK Group: Proven Technology with a Long-Term Perspective
Proven technology deserves a long-term perspective.
Electromechanical relays have been operating reliably in many industrial installations for decades. For long-life systems, such as those used in railway applications, long-term spare parts availability is an important consideration.
A good example is the KAMMRELAIS® from the EBK Group. Originally developed by Siemens, this relay family is still manufactured by EBK to the original design today.
For operators of existing installations, this continuity is particularly valuable. Not every proven component needs to be replaced by a new technology.
Reliability, availability and a secure long-term supply of spare parts are what matter.
As a specialist distributor for relay technology, SHC GmbH also supports its customers in sourcing these proven components.

Optidrive E3 IP66: Decentralised Drive Control Directly at the Machine
Variable frequency drives do not always need to be installed in a control cabinet. Where speed control is required directly at a machine or process plant, a decentralised solution can be an attractive option. The IP66 version of the Optidrive E3 from Invertek Drives combines a protected enclosure with versatile speed control functions.
Optidrive E3 from Invertek Drives: compact version on the left, IP66 version for decentralised applications on the right.
A decentralised approach suited to the application
Whether installation at the machine is appropriate depends on the individual plant. Available mounting space, access for operation and maintenance, and environmental conditions are among the key considerations. For new installations, this approach can be considered from the planning stage. For retrofit projects, it is worth assessing how speed control can be integrated into the existing installation.
Robust enclosure and built-in communication
The Optidrive E3 is available in an IP66 version for applications requiring a higher level of enclosure protection. Modbus RTU and CANopen are built in, allowing communication with a supervisory controller to be considered during system design. Installation must follow the requirements specified by the manufacturer for the selected version.
From the application to the right drive selection
For industrial applications, pumps and fans, selection starts with the required function: Which speeds are needed? How does the load change during operation? How should the machine be operated and integrated into the control system? Motor voltage, motor current, installation layout and environmental conditions are also part of the technical assessment.
SHC GmbH supports you in selecting and sizing the appropriate Invertek variable frequency drive. Contact us with your motor data and a brief description of the application. Together, we can assess a suitable solution for your new installation or retrofit project.
