Sonraíocht oibriúcháin comhla rialaithe ísealteochta íseal
Riachtanais Cumhachta : Is iondúil go n-úsáideann comhla rialaithe ísealteochta leictreachais soláthar cumhachta AC, is é 220V nó 380V voltas rátáilte, is é minicíocht 50Hz nó 60Hz.
Comhartha Rialaithe : Is iondúil go n-úsáideann rialtóir leictreach ísealteochta comhartha reatha 4-20mA nó comhartha voltais 0-10V le haghaidh rialaithe. Raon ionchuir an chomhartha rialaithe
ba chóir go mbeadh sé comhoiriúnach le raon rialaithe an chomhla.
Raon oscailte : De ghnáth is é an raon oscailte de chomhla rialaithe ísealteochta leictreachais ná 0-90 céim nó 0-180 céim. Roghnú an raon oscailte
ba chóir a chinneadh de réir na gceanglas sonrach iarratais.
Raon teochta : Tá comhla rialaithe ísealteochta leictreach oiriúnach do mheáin ísealteochta, de ghnáth raon teochta oibre -60 ℃ go -20 ℃.
Tá ár gcuideachta chomh maith le comhla ísealteochta leictreach, táirgeann sé freisin comhla rialaithe pnenmatic, comhla liathróid neomatach, comhla liathróid leictreach, agus comhla féileacán neomatach, comhla féileacán leictreach, comhla líneach fluairín , etc.
