One Circuit Fits All

One control circuit solution for the whole world

The requirements for control circuits can vary greatly if machines and systems are designed to operate in different regions around the world.

Companies that export a large number of machines to international markets have to create different concepts for control cabinet power supplies. Depending on the target market, they must use different products, have various wiring concepts and/or use different methods to safeguard the mains voltage, and be knowledgeable about a wide variety of different international standards and specifications.

Here’s how delivering to international markets make everyday installations more difficult: Some markets use the metric system, while others the imperial system; sometimes IEC standards are relevant, other times UL standards. Figuring these things out cost time and money! Different products have to be approved, tested for compatibility, engineered into the system and available in the warehouse. Everyone involved in installing control circuits must be familiar with the various norms and requirements. And the having the right parts available in the right markets is a logistical nightmare!

The Solution for the Challenge: multi-norm power supply concepts. One concept that can be used as a standard in all machines and systems worldwide – regardless of their location! Murrelektronik’s product portfolio has many solutions for multi-norm power supply concepts. Our products follow a uniform design and have the approvals and certifications that you need. They have been developed and tested to work perfectly together. Our solutions meet international standards so that your machine or system can be used anywhere in the world.

Advantages of a multi-norm power supply concept from Murrelektronik is that they reduce the number of different products needed, employees only have to be familiar with one system instead of many, reduce engineering time, and NEC Class 2 circuits reduce approval time and control circuits to a minimum. In total: you can optimize material cost and installation time!

Concrete Installation Examples

If you take for example small machines with low power consumption: a Mico Pro® with an integrated 1-phase power supply is the solution! The Mico Pro® modules with NEC Class 2 outputs protect circuits up to max. 100 VA. Everything that is connected to this circuit does not need UL approval due to the NEC Class 2 certification. Using Mico Pro® current monitoring system with integrated power supply reduces the amount of UL certifications needed.

Another example is for larger machines with increased power requirements: a 3-phase Emparro 40A power supply combined with Mico Pro®. Mico Pro current monitoring modules protect I/O modules connected with an M12 power connection that are mounted on the machine.
