1 Eectronic circuit protector ESX10-Sxxx-DC2V-1A-10A Description The mode ESX10-Sxxx extends our product group of eectronic overcurrent protection devices for DC 2 V appications. At a width of ony 12.5mm it provides seective protection for a DC 2 V oad circuits. This is achieved by a combination of active eectronic current imitation in the event of a short circuit and overoad disconnection typicay from 1.2 times rated current. The ESX10-S is a pug-in type and thus aows quick and easy instaation for groups of devices with severa circuits on the power distribution systems Modue 17pus and SVSxx. DC 2 V switch-mode power suppies are widey used in automation today. In the event of an overoad, however, they turn down the output votage which is intended to power a connected oads. So if there is a faiure in a singe oad of the system, the suppy votage wi break down aso in a other oad circuits. Not ony does this frequenty cause undefined faut conditions, but it can even ead to machine stoppages or system downtimes. This is exacty where the ESX10-S comes in by responding to the overoad conditions faster than the switch-mode power suppy. The max. possibe overcurrent is imited to typicay 1. times rated current (see tabe 1). This aows switching on capacitive oads of up to 20,000 µf, but a disconnection wi ony be effected in the event of an overoad or short circuit. For adjustment to the oad conditions the current rating can be seected by means of a rotary switch from 1A to 10A. Status and faiure indication is by means of a muti-cooured LED, an integra short circuit proof status output (singe or group aarms) or via a potentia-free reay contact (change-over contact). Remote actuation is possibe via a remote reset signa. The manua ON/OFF switch on the device itsef aows start-up of certain individua oad circuits. As soon as the ESX10-S detects overoad or short circuit in its oad circuit, it bocks the oad output transistor and disconnects the current fow in the fauty circuit. After remedy of the faiure, the oad output of the ESX10-S is re-activated by an eectronic reset signa or manuay by actuating the ON/OFF switch on the device.
