MICO power control is a standard alternative to mechanical power circuit breakers. When things get critical, MICO safely cuts off. The device is available from SICK .
In existing control concepts, conventional power circuit breakers are used to protect 24V dc circuits. When one current path is overloaded, this often leads to a drop in voltage and detrimental effects on all parallel current paths.
Small cable cross-sections in the field are especially subject to risk of fire through kinks or ruptures in the cable. System down-time is thus preprogrammed. MICO actively prevents this problem.
MICO monitors each current path, signals threshold load and, in case of over-current, switches the specific affected path to the safe state. No side-effects, no saturation voltage, just simple error diagnostic. An additional power supply unit for the controls is no longer necessary.
The compact construction is suitable for large cable cross-sections. Integrated message outputs and remote switching capabilities via push-button or PLC allow well-directed diagnostic and avoid unnecessary deployment of service technicians.
The current range can be defined for each channel individually (up to four channels per module) with a current range selector switch from 1A - 10A in (module-specific) increments.
MICO shortens assembly, wiring and planning times. Machine downtime is minimised. Power supply units need less reserve and can be designed to be smaller.
Existing systems with power circuit breakers can be converted to MICO without difficulty. You save up to 30% space on the DIN rail.
