"The Power-Mate Lite provides instantaneous and cumulative measures of power consumption, running costs and greenhouse gas emissions and forecasts these values going forward per hour, per week, per quarter and per year.

A simple menu allows the home owner to enter their own values as these vary by location and power supplier.

The Power-Mate Lite also provides technical measures such as supply voltage, current, power, VA and power factor."

The above blurb was quoted from the site.

POSTAGE is a flat rate of $9.95 Australia wide.

This meter is VERY ACCURATE compared to the cheaper meters, when measuring power consumed by devices when placed in standby.
Unlike the cheapies, it cannot be fooled by devices with strange power factors.

Unlike most other electronics items, these devices are made and designed in Australia.

    • meroveus on 06/06/2012 - 18:30

      I don't know for sure about the Aldi, but most cheap power meters are accurate for resistive loads only, for reactive loads they can be out by 5, 10 times or even more.
      If you are interested, this article talks about real power vs reactive power

        Please explain for simple (non-electrical engineers.)

        Thanks! :)

        • thefunkygibbon on 06/06/2012 - 22:38

          I think it basically comes down to is if you're interested in knowing accurately what your device is using (especially for low wattage devices or those in standby) then use some like either Power-Mate Lite or the Clever Watt (the steplight website) if your just want to get a gauge as to what your PC is doing then the Jaycar ones are OK.

          That's my non-electrical engineer take on it.

        • Russ on 06/06/2012 - 23:25
          +4

          I'll try to explain simply. Resistive loads draw power throughout each cycle of the mains. Reactive loads are different. For part of each cycle they draw power, for another part they push power back into the mains!

          So if you have a reactive load which draws, say, 100 watts, it may be drawing 150 watts for part of the cycle, then pushing back 50 watts.

          Why is this important? Well, some power meters (including the ones owned by your electricity company and used for billing you) read incorrectly if your loads are reactive.

          There is also the problem of losses in wiring. The 100 watt reactive load will cause higher losses in the house wiring than a 100W resistive load. If you have a very large load which is very reactive, say 2400W, you can actually exceed the 16A rating of the average house wiring, and maybe cause a fire. A resistive 2400W load only draws 10A, well within the rating of the wiring.

          In the above "cycle" means each cycle of the 50Hz mains (50 cycles per second).

          This is a rough explanation and not exactly technically correct.

        • thefunkygibbon on 06/06/2012 - 23:48

          Cool, thanks for the explanation Russ. So the follow-on question for me for this is. How do you tell what is resistive and which is reactive?

        • endotherm on 07/06/2012 - 00:08

          I thought it didn't matter so much in a domestic situation, you are charged the same. In industrial situations they negotiate a different tariff depending on their power factor (dependent on what type of machinery they are using). Some dodgy types try to sell you a power-factor correcting box for domestic users to save money — sounds good in theory until you find out you are being charged on how many kw/h are supplied to your house, not how you use it.

        • endotherm on 07/06/2012 - 00:11

          I think loads like an incandescent light globe are resistive, they consume the same power per second regardless, whereas a motor is reactive — when it is starting up or working hard it is drawing more power, but when it is idling/free spinning it doesn't use as much.

        • Russ on 07/06/2012 - 13:33
          +1

          There are two types of reactive - inductive and capacitive.

          Anything which is primarily a motor (e.g. pool pump, fans, air conditioner) will be reactive in the inductive way. Anything which has a switchmode power supply (most comsumer electronics) will be reactive in the capacitive way, but many high-power items will have a built-in power-factor correction circuit.

          Linear fluorescent lights have a ballast, which makes them inductive (although electronic ballasts don't have the same effect). Such lights often have a largish capacitor in them (about the size of a 35mm film canister) to cancel out the reactive effect. Any inductive load, including motors, can have most or all of their inductive reactance cancelled by adding the appropriate amount of capacitance.

          The only loads in your house which will be purely resistive will be incandescent light bulbs and heating elements - everything else will have a degree of reactiveness.

          How reactive something is is measured by its "power factor", which goes from -0.5 to +0.5. Zero is pure resistive, -0.5 and +0.5 are pure reactive. Average all the loads in a house usually gives a power factor between -0.9 and +0.9, so the remaining reactivity is usually not worth cancelling out.

          For many businesses, e.g. a wood-working shop, they will be quite inductive, due to the large number of high-power motors. Such businesses often install a power-factor correction device (larger than a desktop PC and worth thousands of dollars), as the electricity companies DO measure the power factor and charge penalty rates depending on how bad the power factor is, as correctly identified by endotherm. Domestic situations don't normally get measured.

        • Russ on 08/06/2012 - 23:33
          +1

          Oops, I've just re-read what I wrote, and realized there are one or two poorly explained bits, and a bit I got wrong.

          Here's the re-write of the "power factor" bit. Power factor is a number between 0 and 1, where a pure resistive load has a power factor of 1, and a pure reactive load has a power factor of zero. Most loads actually have a power factor between 0.9 and 1, while some motors will have lower power factors of perhaps 0.6 to 0.8. If anything has a power factor below 0.5, something is probably wrong, it would be very unusual to have something that reactive.

          Adding to that, you have to say if the power factor is "leading" or "lagging", which tells you whether the reactiveness is due to capacitance or inductance. In some industries like power generation, this is indicated more simply by making the power factor be positive for capacitive "leading" loads, and negative for inductive "lagging" loads.

          So, with all the loads in an average house, some capacitive, some inductive and some resistive, the sum effect is that the power going into the house will usually have a power factor between 0.9 and 1. 0.9 is not bad, not much power is wasted due to the reactiveness, so no effort is put into correcting it to be exactly 1.

    I have one of each and they give very different power figures. One reads 53Watts and the other 88Watts with one plugged into the other and then the N40L Microserver to test usage. At least one of them is not right.

    • asa79 on 07/06/2012 - 07:34

      Yes

    • vrsac on 07/06/2012 - 08:30

      On my N40L Microserver I've measured around 45-50W during normal operation. I used a Belkin power meter. I have 5 WD Green HDD's in my microserver and am running FreeNAS.
      I'd say that the one that reads 88W is inaccurate.

    • llama on 06/06/2012 - 21:09

      Clamp on units are pretty much useless because they don't allow for the Power Factor.

      Clamp ones just measure amps, but if Power Factor is less than unity (eg: a fridge, motor, transformer, computer or any other non-resistive load) then the reported figures will be miles out. For example, a domestic fridge has a Power Factor of about 0.5, so the reported "power" will be DOUBLE the real Wattage.

      Also, clamp ones can't measure voltage either. So they just take a guess on TWO of the three measurements required to measure Power Consumption.

    I've looked at the supplier's website (ccisa.com.au), which shows their stock level as 281 units, so there should be little, if any, delay.

    I pointed out that Todae may have committed a breach under the privacy legislation. He was very apologetic about the CC, but had nothing else to say about it apart from that it will not happen again.
