JL18S electronic undercurrent relay  and GL-28S electronic over-currency delay are  new generation that take the place of mechanic current relay. The product transfers the tested current into number format  by sample resistanceand A/D switch circuit. It displays attract current, release current and tested current through 3-digit  LED tubes(By dialing the display option switch). Two comparators in the relay compare the value of tested current with setting value of  attract current and release current respectively. If the value of  tested current is more than the setting value of  attract current,  the  red light on panel will be on; if the value of the tested current is lesser than release  current , the delay will  release energy. The biggest advantage of this product consists in: It can set and regulate attract current and release current directly, and also can choose setting value of attract current, release   current and tested current separately  by display selection switch.
