| SOLUTIONS FOR
INTELLIGENT POWER DISTRIBUTION
Complex power supply systems with many components require reliable
load protection. Switch mode power supplies are the core of these systems
since they electronically monitor output voltage and output current. If
there is a short circuit or an overload, protective devices downstream (for
example circuit breakers) react slower than the power supply and do not
ensure selectivity. This can cause critical situations like voltage drops or
even cable fires.
Our compact MICO modules help eliminate these problems: MICO is an
essential component for protecting power supply systems!

| MICO – Solutions for intelligent power distribution
CASCADING START
MICO eliminates start-up peaks with a time-delayed
(cascading) start of individual current paths. Advantage:
Now you can use power supplies with lower output
current.

Target-oriented protection is a big challenge for modern power supply systems. MICO is an intelligent power
distribution system that meets this challenge! Errors are found quickly while availability remains high.
MICO Monitors Currents: You can select a maximum, individual current value for each
channel and MICO monitors this value. The LED is green when the current is OK.
MICO Indicates When Approaching the Maximum Load: There is a visual alarm when
90 % of the selected current load is reached. The LED blinks green.
MICO Detects Stress: When there are short circuits or if the selected load current is excee-
ded, MICO switches the affected channel off. The LED blinks red.
MICO Provides Flexibility: Each channel can be individually switched off by pressing a but-
ton. Here, the LED is red. Of course, you also can switch all channels on manually.

| MICO+ – appealing features and even more options
Mico saves energy: When loads are switched
on, they need energy. Often current is already
flowing, even though no productive activity is
carried out. For example during pause times:
Energy is consumed as stand-by power, pumps
are running, displays lighten, loads are heating ...
With MICO+ you can switch off all 4 output
channels from a control input during idle times.
This way, only those loads that actually require
energy are supplied. This saves energy, results in
fewer losses, increases lifetime and productivity.
If the part of the machine that was switched off
is needed again, it can be immediately reactiva-
ted with MICO+.

| MICO BASIC – INTELLIGENT SWITCH OFF
As early as necessary, as late as possible – MICO BASIC features intelligent switch off characteristics! The modules are
suitable for any application that requires protection of a great number of sensors and actuators with similar demands.
The current ranges for the individual circuits are fixed. The compact modules secure either four or eight channels with
2, 4, or 6 A. LEDs show the operating conditions of the individual channels and, when blinking, indicate that a maximum
load of 90 % is reached. If there is an overload or short circuit, MICO BASIC switches the affected channel off and the
LED blinks red. A group alarm contact sends the current status to the control.
Switch off supported by microprocessor
Preset tripping currents – 2 A
(the same for all channels) – 4A
– 6A
4 channels – width 35 mm
8 channels – width 70 mm
Less space required compared to conventional solutions

and GND)
