I-DFUN isungule isisombululo sokuhlola umthamo ku-inthanethi esikude samasistimu ebhethri ayisipele angu-48V . Lesi sixazululo sihlanganisa imisebenzi eminingi, okuhlanganisa ukuhlola umthamo, ukukhipha okonga amandla, ukushaja okuhlakaniphile, ukuqapha ibhethri, nokwenza kusebenze. Ibhekana ngokuphumelelayo nezinselele ezifana nesikhathi nomzamo osetshenziswa ukuhlola okwenziwa ngesandla, ubunzima bokuhlolwa kwamandla okungaxhunyiwe ku-inthanethi, kanye nezinkinga zokunakekela ezivela kumasayithi ahlakazekile. Ilungele iziteshi ezingaphansi, izikhungo zokulawula, nezitshalo zamandla okugcina amandla.
