2 A, with transistor-output

The STWA1SH has an integrated electronic with transistor-output. The switching point is 2 A. Above app. 2 A the output transistor is switched on below app. 1.5 A it is off. The conductor is simply pushed through the transformer.Multiple loops reduce the switching point corres pondingly, for instance to 0.5 A with four loops. A supply voltage is not required. used where current flow is to be detected, with the exact value of the current either known from the power consumption of the connected consumer or does not matter for the evaluation. For simultaneous evaluation of the current flow in several conductors the STWA 1 S device can be connected in series (AND circuit, pay attention to the voltage drop) or in parallel (OR circuit, pay attention to the leak current). isolated transistor-output max.
