Someone on the internet busted one open to examine the guts. The unit is comprised of one (1) 100µF, 150 VAC, 60Hz electrolytic capacitor and an integrated circuit that controls a light emitting diode (LED). And certainly not in the way the manufacturers recommend that they be installed, that is, permanently connecting them at the main panel. Doing that drags the power factor capacitive when the inductive motors are off and could create some real problems with ringing voltages.

The third term is apparent power, referred to as KVA. By use of multi meters we can measure current and voltage and then multiply the readings together we get apparent power in VA. So, I would have been the guy, excitedly, pointing out which of Mr. Barnums displays were hoaxes. In fact, you’d of likely seen me being thrown out for it & later read my article about it as well.The second term is reactive power, measured in KVAR. Unlike kW, it cannot perform work. Residential customers do not pay for KVAR, and utility meters on houses do not record it too. Third, you say “there are no electricity saving benefits for heating appliances, such as electric stoves, electronic cookers, etc.” So wh;y bother with your device? Please elaborate on the “etc.

Consider a bulb consuming 100 watts of power at 220 volts. This simply means at 240 volts it will use up about 109 watts of power. The rise is just of around 9% and since such fluctuations are pretty seldom, this value may be furthermore reduced to less than 1%, and that is negligible. In the second expression we clearly show that a reduction in current consumption by the refrigerator, but interestingly in both the above cases, the Real Power remains the same, i.e. the refrigerator continues to consume 100 watts, and therefore the utility bill remains the same. This simply proves that although the PF correction done by an energy saver may decrease the Amperage of the appliances, it can never bring down their power consumption and the electric Bill amount. So I guess it depends on how many motors you have in your house and when they turn on. I have many different devices, not counting the occasional power tool. He said that Jumbo has defect on the products. Yes,Jumbo isn’t 100% perfect and we still have a long way to improve the quality and everything and now we are doing that to make ourself better and better.Besides, I have the confident to say that we are the best power saver manufacturer in China. Maybe customers don’t believe what I say, then you are welcome to compare any other brand from China with Jumbo and tell us the disadvantages. Most welcome. All you did here was try to discredit Mr Sun because his words and due to your business dealings not working out. You resolved your issues with him, move on.

New Customer?

Reactive power is not a problem for a Reactive Load of Home appliances like A.C, Freeze, motor for its operation. It is a problem for the electric utility company when they charge for KW only. If two customers both use the same amount of real energy but one has a power factor of 0.5, then that customer also draws double the current. This increased current requires the Power Company to use larger transformers, wiring and related equipment. Power cleaning is installed at the point of use of equipment – it will save a small amount of money but is normally used to protect vulnerable equipment (computers) from waveform spikes. This has been overtaken in the UK by the 18th Edition regulations which requires Surge Protection to be intalled at the fusebox. Many people who have used these power savers said that they could reduce their electricity bills with the devices; however the reduction was not as much as they had expected. Moreover, they could not figure out if the reduction in electricity bills was due to the power savers or because of their efforts to reduce their electrical usage. There have been several serious discussions about the genuineness of the device. Thus the above discussions convincingly prove that energy savers can never work and the concept is not practically feasible. Paper plates!!?? Aaaaaah! Super-wasteful of raw materials and money, and add to the mountains of waste. Where do you think “away” is, anyway?

Basically it is claimed that Power savers work on the principle of surge protection technology. Power savers work on straightening this unstable electric current to provide a smooth and constant output. The fluctuation in voltage is unpredictable and cannot be controlled. However, the power savers utilize current fluctuation to provide a usable power by acting like a filter and allowing only smooth current to pass through the circuit. Power savers use capacitors for this purpose. When there is a surge of current in the circuit, the capacitor of the power saver stores the excess current and releases it when there is a sudden drop. Thus only smooth output current comes out of the device. If every house and industry fitted these power saving devices to clean up the signal and they incorporated an additional activation/deactivation circuit fur when ac unit or fridge/freezer motors and industrial motors and charger units and power tool transformers were active/inactive, then the power station sacrifice theory would be unnecessary, the signal would be clean, the power consumption would go down, all at cost to industry and households (who weren’t being directly charged in single additional surcharge form anyway, only through annual rise in unit price), the power companies would continue to raise prices and unit charges and not tell everyone that they (the public) were the ones cleaning the signal but that it was the actions of they (the power company) at their own cost and effort with rising prices on wages and materials and continue to raise surcharge anyway.. You speak too much about Mr Sun and not enough about your product and proof of concept that it works, as well as explaining how.

If the wire between your fuse panels is very long and undersized, reducing the current would result in it running cooler and having a higher voltage at the air conditioner. These savings due to cooler wiring is minimal. What happens when Power Saver is installed only power saver 3 phases with a kvar capacitor and controller Power factor, c/k and more can true save, depends the inductives load. if good for hotels or place use for sample many air conditioner. here can get good result saving.

Delivery times are quoted in business days meaning weekends and local holidays including bank holidays, Christmas etc do not count as business days. DELIVERY TIMES - Custom Made Products Many people believe that the claims made by the power savers manufacturing companies are false. Almost all people who buy power savers do it to reduce their electricity bills.If you really want to be headache, just try to do business with him. I do believe that he got lots of bad buying history in China. And you will be 100% unhappy.
