System components: Fieldbus power supply SFC260

The modules SFC252 and SFC260 are 24 VDC fieldbus power supplies for use with e.g. a SFC363 power conditioner. The only difference between them is the external supply voltage that they require: SFC252 (90 VAC - 264 VAC) SFC260 (20 VDC - 30 VDC) The SFC252 fieldbus power supply is non-intrinsically safe with an universal AC input (90 to 264 VAC, 50/60 Hz or DC equivalent), and a 24 VDC output. The output is galvanically isolated from the input, with short-circuit and overcurrent protection, ripple and fault indication, appropriate to feed fieldbus devices. There is no electrical connection to the backplane. The SFC260 fieldbus power supply non-intrinsically safe with a DC input (20 to 30 VDC) and a 24 VDC output. The output is galvanically isolated from the input, with short-circuit and overcurrent protection, ripple and fault indication, appropriate to feed fieldbus devices.
