Equal or better compliance

[i] Power consumption varies slightly depending on supply voltage and signal conditions. Efficiency is shown proportionate to available VA output.

[ii] Short-term peak at maximum rated 1kHz sine output signal.

[iii] At unit max current, single-turn loop with 2.5 mm2 loop wire and up to 3 m twin twisted 2.5 mm2 feed cable driver to loop. The best loop installation for a project may differ. Please consult Ampetronic for more details.

[iv] At same current as XA88 maximum a T14-1 loop may be up to 49 m x 2.8 m, i.e. 225% more / 3.25x capability. At full T14-1 current a shorter loop can be driven. Based on 2.5 mm2 copper wire loop, 1-turn.

[v] XA88-24DC-2 does not have a floating power supply; the supply is ground-referenced. This is compatible with most operating environments experienced. The T14-1 (all versions), XA88-72DC-2 and XA88-110DC-2 all have a floating power supply.
