Mico Pro is the intelligent current monitoring system from Murrelektronik. The modular design enables the system to be built precisely to suit specific applications while maintaining an excellent price-performance ratio and saving installation space.
The patented tripping process ensures optimum machine availability. Mico Pro® monitors load and control currents, and identifies critical moments. It signals limits and switches defective channels off as late as it’s safe, but as safe as possible.
Two new extended system features now make Mico Pro® even more versatile:
Full Power! Mico Pro® available with integrated power supply
New switch-mode power supplies with an output current of 5 or 10 A can be integrated directly into Mico Pro® stations. This combination creates more space inside the control cabinet because it replaces the power module. The switch-mode power supply continues to support features like general alarm message, 90 percent early warning, control signal for remote maintenance. You can also supply up to 20 A of power by enabling the parallel mode. Energy efficiency is high, keeping control cabinet temperatures low. With practical bridges that snap in, the switch-mode power supply devices can be connected to the monitoring modules in a few easy steps, without the need for extra wiring.
NEC Class 2 – facilitates the UL approval process
Murrelektronik has a large number of Mico Pro® modules with NEC Class 2 certification and – a remarkable feature – are capable of monitoring current of up to 4 A. This enables many NEC Class 2 load circuits to be integrated with a powerful switch-mode power supply. According to UL: due to the limited amount of energy (100 VA) in power circuits of this kind, there is neither a risk of electrocution nor any fire hazard. This is why the control cabinet components (acc. to UL508A) used in a Class 2 circuit do not need to be certified by UL. This simplifies the approval procedure for control cabinets. Further advantages: free up space in the control cabinet, easy choice of a standard power supply (from Murrelektronik of course) and a substantial reduction in the amount of wiring.
