Boto ea tlhahlobo e matlafatsoa ke ho hokela sekhahla sa DV biastage pakeng tsa VCC le GND Pins ho PCB. Pini ea OUT ea PCB e lokela ho hokeloa ho voltmeter ea dijithale (DVM) kapa oscilloscope ho beha leihlo tlhahiso ea sensor ea hajoale ea CT220. Lintlha tse teng karolong ena ke tsa 5 V bias voltage.
Boemo bo Tlase-Hajoale
Ka mokhoa o tlase-hajoale, ea hajoale e feta 0.9 mm-wide-wide trace on the top layer of the PCB. Mokhoa ona o ka sebelisoa ho lekanya maqhubu ka har'a ± 3.85 A. Ho hlaka pakeng tsa trace le IC pads ke 0.35 mm, e fanang ka ho itšehla thajana ha 1 kV pakeng tsa trace ea hona joale le SOT23 pins. Ho phaella ho tatellano e babatsehang ho pholletsa le mocheso, tekanyo e phahameng ea signal-to-noise (SNR) ea CT220 e e nolofalletsa ho lekanya maqhubu a tlaase haholo. CTD221 e khona ho bona maqhubu a tlase ho 5 mA.
Boemo bo Bohareng ba Hona Joale
Ka mokhoa oa sejoale-joale, ea hajoale e feta 2 mm-bophara ba mohlala karolong e ka tlase ea PCB. Tsela ena e pharaletseng (ha e bapisoa le mokhoa o tlaase oa hona joale) e lumella hore ho fumanoe hore e kholoanyane hona joale. Mokhoa ona o ka sebelisoa ho lekanya maqhubu a ± 10 A, ka bokhoni ba ho rarolla ka mehato ea 10 mA. Karohano ea CT220 bakeng sa tlhophiso ena ke 5.1 kVrms hobane sebaka se pakeng tsa trace e tlase le SOT23 pins ke 1.6 mm.
Mokhoa o Phahameng oa Hona Joale
Mokhoa oa hajoale o sebelisoa bakeng sa lits'ebetso tse kenyelletsang maqhubu a maholo haholo hore a ke ke a feta har'a mesaletsa ea PCB. Ka mokhoa ona, hona joale ho fetisoa ka busbar ea koporo. Busbar e bophara ba 1/2" le 1/16" e teteaneng. Mosebelisi o na le monyetla oa ho fetola sebaka sa busbar ho tloha sebakeng se kaholimo sa PCB a sebelisa liwashara tsa polasetiki tse hananang le khalefo. Boto ea tlhahlobo ea CTD221 e romelloa ka li-spacers ho boloka lekhalo la 4 mm pakeng tsa PCB le busbar. Ka tlhophiso ena, CTD221 e ka sebelisoa ho lekanya maqhubu ka botlalo ba 50 A le ho lekanya maqhubu ka har'a ± 50 A ka qeto ea 50 mA. Ka sebaka sa sebaka sa 4 mm pakeng tsa CT220 le busbar, ho itšehla thajana voltage feta 5.1 kVrms ka mokhoa oa hona joale o phahameng.
