LÜTZE
LOCC Box DC Electronic Fuse for 24V dc circuits, 0.2-2A
The LOCC-Box modules are suitable for fine tuning of the current ranges up to 2 A and are therefore ideal as an alternative to small glass fuses. LÜTZE's LOCC-Box (LÜTZE Overload Current Control Box) is the first intelligent current control system. Intelligent current control means that the LOCC-Box allows the development of a selective power supply. The benefit: In the event of a fault, only the affected circuits are shut down. Other unaffected circuits can continue to function.
In addition to protecting the units and wires, they also assume energy management tasks. The easiest task is targeted activation and deactivation of consumers. Any type of consumer, be it ohmic, capacitive or inductive, can be used. There are various jumper combs available (8 and 16-pin in the colours white, blue and red) to reduce wiring work. There are 3 characteristics (fast, medium and slow_1) available for the new DC 2 A module; these can be set with a rotary knob just like the current ranges (0.2 A to 2 A).
The status output can be issued as a single-channel or collective malfunction. The LED status indicates the operating modes 'Off', 'Triggered' and 'On'. The power supply is connected via screw-less contact slides that allow a galvanic separation when servicing is necessary.
All modules of the LOCC-Box series can be combined in one system design. Summary: The LOCC-Box is a modular series that converts all the negative properties of a circuit breaker into advantages and also offers additional features!
