The AP9046 is useful in any two-wire transmission application to power the current loop. The 24VDC regulated output provides maximum loop drive capability without exceeding intrinsically safe voltage requirements. For installations where intrinsic safety is not a factor, the 40V unregulated output provides increased loop drive. The current rating of the AP9046 allows it to power up to three standard 4-20mA current loops simultaneously. The AP9046 can also be used as a general purpose DC power supply for alarms and indicators, or any application requiring 24/40VDC at up to 65mA.
