This low current sensor breakout is capable of sensing very small currents down to around 10mA and large currents up to 5A!
Basic Isolation Working Voltage = 420 Vpk / 297 Vrms
The breakdown voltage for air is 3 million volts per meter , or 3000 V/ per mm, so if the mfg says its rated for 297 V I don't see any reason not to believe it . It would take 300V to arc 0.3 mm so I' sure there's more than enough clearance for isolation.
dear forum i'm new from here, i am trying to make a little circuit with arduino nano or arduino 2009 but not safe of what to do, i've yet done some circuit but more easy.i have done lot of researches on the google and this forum but got a lot of confusion...explaning a litle bit my problem. i have an apareatur that work with 230 volt AC this object have on board voltmeter and ammeter i've got some problem with it so now i need to insert a monitor that when the power absorption start (0,3/05 Ampere)a bulb get switch on, then when the absorption reach 1,3/1,5 Amp. a buzzer comunicate it.and in the same time i've to register the value if possible with date/hourcan someone help me ?i don't need a display because i'm planning to leave the original ammeter because i can't broke original schematic. ive seen the SCT-o13-030 toroidal trasformer it it ok? or acs712 from allegro many thanks to all can help me with sketch etc sincerelly sergio _T
And how much would it be with condensation on a dirty PCB.I don't see any milled slot in that Sparkfun board.Tinkerers in the US can be less concerned with 120volt AC.Leo..
