FAQ – Frequently Asked Questions about Power Supplies and IIoT
How is Power Supplies used in industrial systems?
Power supplies are used to feed, protect, and monitor electrical and electronic systems in industrial environments. For example, the solutions are used in:
Common uses:
- Cabinets and Enclosures
- Automation systems and PLC
- Connected IIoT devices
- Industrial communication and monitoring
Therefore, the choice of power supply affects both operational reliability and system lifespan.
When is a neighboring product area more relevant?
Power supply and IIoT encompass several solutions with different focuses. In some cases, therefore, an adjacent product area is a better fit. For example, you can base your choice on the following needs:
- If the focus is on enclosure, assembly or mechanical construction rather than electrical supply → choose cabinets and enclosures
- If the challenge concerns heating, ventilation or cooling in the cabinet → choose climate control for cabinets
- If the installation concerns cabling and bushings rather than power and monitoring → choose a cable entry system
When is a industrial PSU the right choice?
Power supply in industrial environments provides machines, control systems, and other equipment with stable electrical power. For example, power supplies, UPS, and DC/DC converters are used for various needs. Thus, the risk of downtime and faults is reduced.
What is a PSU in industrial applications?
Power supply in industrial environments provides machines, control systems, and other equipment with stable electrical power. Depending on the application, you can use power supplies, UPS units, or DC/DC converters. In this way, you can increase operational reliability and reduce the risk of downtime.
What type of PSU's do you offer?
We offer power supplies and PSUs for DIN rail mounting. The range includes several voltage and power levels. Therefore, you can choose a solution based on your application's requirements for power, format, and performance.
What is the difference between a switch and a router for industrial use?
A switch connects devices within a local area network (LAN) and forwards data efficiently. In contrast, a router connects different networks, such as a local network and the internet. This allows the router to direct traffic between the networks. Furthermore, our industrial 4G routers enable wireless connectivity for remote control and IIoT.
How do I know which solution suits my system?
The choice depends on your application. Therefore, we recommend that you contact our team with information about your system. That way, we can help you choose products based on power requirements, environment, and desired features.
Can I get help with technical support or advice?
Yes, our experienced team will help you with technical support and advice. For example, we can help with product selection, dimensioning, and installation.
