Load Monitoring System

Automation specialist Friedrich Lütze has introduced a new electronic load monitoring system for 1 A to 10 A DC that permits the selective protection of individual 24 V DC circuits, each with different tripping behaviour. As well as enabling capacitive loads to be started via a "Power-On effect", the Lütze LOCC-Box load monitoring system also makes it possible – in the case of an overload or short-circuit in 24 V DC circuits – to switch off just the defective current circuit without any repercussions on the supply. In order to satisfy the very diverse demands concerning the tripping behaviour, the LOCC-Box allows for ten different characteristics to be set via a switch. As well as the well-known characteristics from the circuit-breaker sector, provision is also made specially for implementing customised characteristics. In addition, the rated current range is selectable from 1 A up to 10 A using presets. This is very important when retrofitting, as here the device protection often has to be modified and adapted to suit. Features: adjustable characteristic; adjustable rated current; “Power-On” effect to switch on capacitive loads; single devices can be removed, without interrupt the supply circuit; response time independent of temperature; non-volatile storage of the last status; and single or centralised Alarm output.
