Features

* No potentiomenter required Direct interface to SCR Supply voltage derived from AC line
* 26V shunt Adjustable sensitivity
* Grounded neutral fault detection Meets U. L. 943 standards 450µA quiescent current Ideal fo

Applications

* Shunt Regulator RLINE limits the current into the shunt regulator; 220V applications will require substituting a 47kΩ 2W resistor. In addition to supplying power to the IC, the shunt regulator creates internal reference voltages (see above). Operational Ampliﬁer RSENSE is a feedback resistor that
