The DF52 power supply unit is a non-intrinsically safe equipment with an universal AC input (90 to 264 Vac, 47 to 63 Hz or 127 to 135 Vdc), and a 24 Vdc output, isolated, with short-circuit and over-current protection, ripple and fault indication, appropriated to power fieldbus elements.
The DF60 power supply unit is a non-intrinsically safe equipment with a DC input (20 to 30 Vdc) and a 24 Vdc output, isolated, with short-circuit and over-current protection, ripple and fault indication, appropriated to power fieldbus elements.
