Web家庭用の電圧は一般的には100v、工場などの生産機械には200v以上が使われています。 電気の流れる量＝電流を表す単位がアンペアです。 家庭では20Aや30Aなど、ご使用状 … Web1 Answer. You could return the LED to a fixed negative voltage of (say) -1V to control where it turns on. Or (better) put the LED in a feedback loop so that you get mA out for volts in. The latter will eliminate the LED 'on' threshold entirely- if that's acceptable (it might glow very slightly with zero input).

WebLow impedance system wired in parallel to increase the qty of loudspeakers while matching the impedance load to the amplifier. High impedance systems include 25V, 70V or 100V options. 100V is the common derivative used throughout the UK and Europe. High impedance (or 100V) systems are regarded as being relatively simplistic. WebJul 3, 2024 · As the capacity is high (50 amps), the inflow in the limiting circuit with Re1 switch and also on R2. The relay coil and fan, taken from AT or ATX power supply is powered from 12V. The power is obtained via the resistor from 17V auxiliary supply. It is ideal to select R1 so that the voltage at the fan and the relay coil limits to 12V. over service launcher
