Asɛmmisa: Voltage nhyehyɛe bɛn na [DFPM91] no ne no hyia?
A: [DFPM91] no ne 110V, 120V, 220V, 230V, ne 240V AC low voltage nhyehyɛe ahorow no hyia, na ɛma ɛfata ma nnwuma ahorow pii.
Q: So metumi de [DFPM91] no ahwɛ ahoɔden parameters pii?
A: Akyinnye biara nni ho! [DFPM91] no ma wo kwan ma wohwɛ voltage, current, power, reactive power, aparent power, power factor, kilowatt-hours, ne kilovar-hours, na ɛma wunya ntease a edi mũ wɔ ahoɔden a wɔde di dwuma ho.
Asɛmmisa: So instɔlehyɛn no yɛ den?
A: Ɛnyɛ saa koraa! [DFPM91] no wɔ 35mm DIN keteke kwan a wɔde ahyɛ mu a ɛne DIN ED5002 a wɔahyɛ da ayɛ no hyia, na ɛma ɛyɛ mmerɛw sɛ wode bɛhyɛ wo nhyehyɛe a ɛwɔ hɔ dedaw no mu.
Asɛmmisa: So metumi de [DFPM91] no abom ne nhyehyɛe afoforo a wɔde hwɛ nneɛma so?
A: Yiw, [DFPM91] no de LED pulse output a ɛnyɛ den sɛ wɔde bɛka nhyehyɛe anaa mfiri afoforo a wɔde hwɛ nneɛma so ho.
Asɛmmisa: Nkitahodi nhyehyɛe bɛn na [DFPM91] no boa?
A: [DFPM91] no boa MODBUS-RTU ne DL/T645 protocols nyinaa denam ne RS485 port so, na ɛma ɛyɛ mmerɛw ma nkabom a ɛnyɛ den.
