Mico, the intelligent power distribution system from Murrelektronik, monitors current, indicates current rating and detects overloading. This product range has been supplemented with a 2-channel version, which enables the design of more efficient and easy-to use systems.
Power supply systems have to combine two functions: the need to provide high inrush currents for the startup of an installation, while at the same time they have to ensure a reliable shutdown in case of short circuits or overloads. When using only circuit breakers it is difficult to meet these two requirements in accordance with the applicable standards.
Slow blow fuse characteristics can cope with high capacitive loads, however, they do not reliably react in case of short circuits. In case of a failure the user cannot see which path shows the fault that caused the shutdown. Fast releasing circuit breakers reliably react in case of a short circuit, but with high capacitive loads they react too fast.
Mico supports high capacitive loads (up to 20 mF) on the one hand, and on the other hand it detects overloads even during running operation and safely shuts down. It monitors each current channel using the selected current range. If everything is within safe limits, the corresponding LED lights up green. The LED starts blinking when 90% of the maximum rating has been reached, giving a visual warning. If the selected current range is exceeded, the current path affected will be switched off and the LED starts blinking red. The user can now see at a glance where the fault occurred. This state will be stored and maintained even if power is lost and the application is powered up again.
The modules are equipped with two or four bridgeable channels, so that they can easily and quickly be connected via a bridging system. Thanks to an integrated floating alarm output, the laborious connection of auxiliary contacts is not necessary. In order to obtain a group alarm it is enough to connect a cable to the first and to the final module. The module is equipped with spring clamp terminals, reducing the time required for the connection and ensuring safe contacts in case of vibrations. The integrated labels make identification very easy.
