test campaign with electricity consumption PM230

[SixK]

4) Samsung SyncMaster 913V Flat Screen : 26 to 30 W (30 W at startup) it seems to consume a little less when it is hot.

For an 19 26 W I find it quite reputable.
It does not seem that there is variation according to the "colors" of the screen. In other words a very dark or very clear screen gives the same consumption ... Behind the screen is noted: AC 110-230 V / 0.7 A ...

0.7 I guess it's the maximum amperage because if it consumes 0,7 A 230 V it would give 160W ... and even in 110 V it would be 77W

What power is the 913V given for? I have the 913N given for 38W Chances are it will be pretty much the same, so the samsung screens would have a lower consumption than that announced This is rather good news. It is true that it heats that slab this screen compared to other LCD screens

we could know the TV standby consumption? very important because a lot remains on standby
you should take all the measurements in a table

Uh if you want to know there is a solution: take a PM230

In addition it will make additional measurements for the table

It's over there :

ps: the answer was given above it seems to me ...

I expected that

Well, it’s time to take economic action, huh
May it not always be the same toast ... uh who is sweating ... sorry ...

When I see the consumption of modem transformers, it makes us think about unbundling.
And yeah, with the phone plugging into the modem, you have to keep the modem running all the time.

Just a small correction:

There is no direct relationship between unbundling and the IP phone.

Unfortunately not being in a grouped area, I can still have an IP "line" and consume 24 hours a day

That said, your remark is excellent for the IP telephone

PS. I don't have an IP line

With Delnoram we found that the PM230 had, at low electrical power measured, an error "window" of 2.3 W ... the measured consumption is therefore not as reliable as advertised but after verification the reality would in fact " worse "than what was measured with the PM230 which would tend to minimize consumption at low load ...

I let Delnorman, who made the calibration measurements explain in detail his findings ...

Alright Christopher:
Already a correction, I may have expressed myself poorly in my MP,
The PM230 seems rather to give consumption over rated.
Eg it announces 16.1W for a voltage of 230V Cos (phi) = 1
the number of Watts consumed is between 13.8W and 16.1W.

I made comparative measurements on several resistive type sources with the PM230 and 4 Ammeters (including 2 somewhat accurate in terms of display accuracy).
But the results were numerous enough in the same direction (all) to be able to draw a conclusion.

Note that the lower the Cos (phi), the better the measurement.

After ~ 920Watts, the double window ~ 4.6W, but at this level the variation is between 0 and 0.5%, in other words negligible.

In short nothing dramatic, but it's good to know .

Unpacked this evening, I measured the instant consumption of:
- philips portable radio-cassette player from 2000. made in china, 17w announced. consumes 11w off as on !!!
- phone dect alcatel versatis 2005. made in china consumes 7w, this seems correct to me.
I already feel that some habits will change ...
