PR314/ Electronic Circuit Protector ESX10-TC in 12 V-version Electronic Circuit Protector also for battery—buffered applications in solar technology and automation Product group of electronic circuit protectors ESX10-T now available for DC12V Altdorf, 16.11.2009 – E-T-A Elektrotechnische Apparate GmbH, located in Altdorf, Germany, specialist for protection, switching and power management, have extended their product range by the electronic circuit protector ESX10-TC for DC 12 V applications. It is a track-mountable unit which allows optimum protection also in combination with DC 12 V switch-mode power supplies and battery systems. The space-saving device has a width of only 12.5 mm and 80 mm each in height and depth. Its low power consumption makes it ideally suited to battery-buffered DC 12 V applications, for instance in solar technology. The ESX10-TC is also a very good choice for applications in factory automation and test equipment in car manufacturing because it allows realising a consistent DC 12 V voltage platform from the test equipment to the actual motor control units. In addition the new circuit protector features switchable load outputs, significantly minimising contact wear when switching on and off. The ESX10-TC is track-mountable, either individually or in groups mounted side-by-side. It offers a sophisticated busbar concept for PR295/Electronic Circuit Protector ESX10-T 3/3 line feed and zero potential. The rail terminal side of the housing has two small plastic slides which can be removed if required and can be slid into the matching slot on the side to close off the busbars. This reliably prevents mutual contact of different plus potentials. The DC 12 V line entry as well as the load connection to protected plus and neutral are via screw terminals up to 10 mm² directly on the devices. The screw terminal is made of a high-strength copper alloy and has been designed in accordance with the patented Reakdyn principle. It ensures reliable and safe cable connection. Reliable selective load protection The selective load protection with fixed current ratings from 1 A to 10 A ensures exclusive disconnection of the faulty path in the event of an overload or short circuit in the load circuit without repercussions on the DC 12 V power supply. Thus it is prevented that a failure in a single load circuit causes a voltage dip which would have all loads connected to the switch-mode power supply fail and which – as a worst case scenario – might lead to a total system standstill. Type ESX10-TC limits the short circuit current to 1.3 to 1.8 times rated current and disconnects the faulty circuit after 100 ms. Inrush peaks, however, are tolerated – capacitive loads of more than 20,000 F can be switched. In the event of an overload the circuit protector disconnects already at 1.1 times rated current after 3 seconds and signals the failure to the control unit via an integral control output.
