The F3-09Ex intrinsically safe power supplies are provided with two independent, separated output circuits of 12V DC nominal voltage. There are three versions of the circuits available that differ in current capacity (1.5 A, 2.0 A; 3.0 A). Operating status of each channel is indicated by LED diode and the control contact.
The F3-09Ex provides „ia” explosion protection level.
