![]() ![]() As 230 VAC will rectify to far more than this the unit would be unable to reduce the DC rail low enough. At 110 VAC the DC out of the PFC IC is 220 VDC at full LED brightness. The brand is a good one but the voltage from clean 230 VAC and spikes or surges could easily destroy it.īlack 4 led IC is a bridge which rectifies mains and drives 6562 PFC IC. I'd post this in answer but that's not possible.Īs can be seen, main capacitor is 315 VDC rated. So is such an LED at all compatible with a 220V mains country? And if not, how can one work around this limitation? This is a high-quality LED bulb (93 CRI and an R9 of 60), and the model is unavailable for European voltages. ![]() The trouble is of course that the light bulb was designed for 120V mains voltage, while in most European countries the voltage is 220V-240V. Thus 220 volts would move 50 less amps than 110. Algebraic manipulation V/A R hints that as volts go up, amps go down. To avoid this issue, make sure that you use a different outlet for the two types of appliances. In addition, the electrical current can cause a fire hazard. The voltage is too high for the electrical wires, causing the conductors to overheat. Herr Ohm passed a law a while ago which requires Volts Amps X Resistance. When you plug a 240V appliance into a 120v outlet, it won’t work. On the packaging it says "Use only on 120 volt AC circuits." and on the light-bulb itself it says "120V~, 60Hz and 112mA." Actually VA but thr heater is pure resistance so it doesnt matter. "If I had eight hours to chop down a tree, I'd spend six sharpening my axe." - Abraham Lincolnįor the best use of Eng-Tips, please click here -> FAQ731-376: Forum Policies RE: 208 vs 220 single phase what's the diff.Would an excellent LED light bulb like the Cree 60 Watt Replacement TW Series (designed for the US market) work in European countries? Sounds as though someone in your company failed to anticipate that possibility. But if you go somewhere that has 208V 3 phase service, like a large commercial / light industrial installation, more likely there are other things nearby that generate noise. If the normal use is residential / light commercial where one would find 120/240V single phase service, noise is generally not a problem. Noise issues are more likely a result of poor filtering design. ![]() But most Servo motors are rated under 200VDC and the amplifiers limit the available peak to what the motor actually needs, so that 5% loss is not likely a problem. Disconnect all 3 from the panel and all 3 from the receptacle (which you already did, but just clarifying for this test). ![]() You should have on each end 3 wires - hot/neutral/ground. Check with an electrician if you are not sure about doing this project. Piuctures of the (open) panel are welcome, maybe higlighting the the involved breaker. It looks like you have 115 volts (1 hot and 1 neutral) passing through to feed an outlet. The peak DC voltage you end up with is limited to 141% of the incoming supply, so at 208V you will have 5% less top end, but still 293V. It looks like you have 230 volts (2 hot) going from terminals 2 and 4 to the pump and old lectranator (this is load out). Servos use DC so the amplifiers are just rectifying the AC to DC. So just double check that your power supplies are rated +-10%, you should be fine. Since a 220v system uses half the amps allowing you to use smaller wiring this also makes it twice as safer then a 120v system since the ps needed are reduced. Distinguishing whether a volt outlet is a 220 or 240 one can be relatively easy even for anyone who is not an electrician. 110V heaters usually max out at just 1.0kW, which can take a long time to heat, or. LARGER HEATER: 220 volts can power larger electric elements, 4kW or 5.5kW. Smaller tubs (under 300 gals), can sometimes overflow when 2 or 3 people climb in the tub. 110V is a similar compromise between 100V (japan) and 120V (North America). A larger body of water, with a larger filter is easier to keep clean than a smaller hot tub. If your company's devices are rated 110V or 220V, that is likely a conscious decision so that they can be used +-10% in many areas. ![]()
