Electronic Circuit Protector ESX50D-S (ControlPlex®) Description The type ESX50D-Sxx is an electronic circuit protector capable of communication, which forms the intelligent power distribution system ControlPlex® type SVS201-CP together with the bus terminal controller CPC10 and the power distribution board SVS201-PWR By means of its communication interface, the measuring values recorded by the ESX50D-Sxx will be forwarded to the CPC10 via the proprietary device bus ELBus® and then to a superordinate programmable control unit. This allows flexible adjustment of the current rating and its parameters to the requirements of the system and its direct controllability. So the user can import the relevant information regarding his DC 24 V voltage supply and process it accordingly. The ESX50D-S is available in two different versions. The first version has a rotary switch to allow current rating adjustment directly on the circuit protector in a range from 1 A to 10 A. The second version offers this adjustment feature via a field bus system or a USB service interface. At a width of only 12.5 mm the ESX50D-S provides selective protection for all DC 24 V load circuits. This is achieved by a combination of active electronic current limitation in the event of a short circuit and by a parameterisable overload disconnection. A typical application is the protection of DC 24 V switched mode power supplies which are widely used in in factory automation today. In the event of an overload, however, they turn down the output voltage which is intended to power all connected loads. So if there is a failure in a single load of the system, the supply voltage will break down also in all other load circuits. Not only does this frequently cause undefined fault conditions, but it can even lead to machine stoppages or system downtimes. This is exactly where the ESX50D-S comes in by responding to the overload conditions faster than the switched mode power supply. The max. possible overcurrent is limited to typically 1.4 times of the selected current rating (see table 1). This allows switching on capacitive loads up to min. 20,000 µF, disconnection is effected in the event of overload or short circuit or at undervoltage and overheating. Visual status and failure indication is by a multi-coloured LED on the protector and is transmitted to the superordinate control unit via the communication interfaces. The manual ON/OFF swtich on the device as well as the control units which are programmable from memory and which are connected to the communication interfaces allow the start-up of selected load circuits. As soon as the ESX50D-S detects an overload or short circuit in its load circuit, it blocks the load output transistor after a parameterisable period of time and disconnects the current flow in the faulty circuit. After remedy of the failure, the load output of the ESX50D-S is re-activated by an electronic reset signal or manually by actuating the ON/ OFF switch on the device.

Machinery Directive 2006/42/EG and EN 60204-1, Safety of Machinery).
