Q: The leads look corroded in the pictures. Are the resistors OLD?

zapytał PC317 na 2021-03-22 01:09:39

jmalima69 The resistors are new and have tight tolerances. I didn't see any signs of corrosion in the product, but I also don't see any signs of corrosion in the picture.

jmalima69 Update: I didn't succeed in programming these devices using the Arduino way of uploading sketches. Either there was a problem my USB-TTL adapter is not compatible with these devices, or there was a problem with the bootloader. Maybe there was no bootloader at all, but there was no mention of that in the product description. Finally I managed to program the device via ISP. Programming via ISP is not so difficult, if you have another Arduino (or an ISP programmer) and brings some advantages. But if you plan to buy these modules beware that you might have problems uploading sketches the usual way.

2.2KW 380V 3PH VFD Falownik Napęd VFD o zmiennej częstotliwości do sterowania prędkością silnika
US$161.69 US$176.99

Q: I have a 2-column spindle lift. This is at 380 volts but I now want to connect at 230 volts. The plug attached to the bridge has 4 poles 3 phase and earth. Can I use this controller for that?

zapytał Bornnanne na 2019-06-26 11:15:17

jmalima69 Thisis a converter from 230VAC single phase to 230VAC x 3 phases (380 VAC between phases), 2,2KW total power. Whether this works for a particular 3 phase AC motor depends on the power requirements of that motor and whether it is a 380VAC motor.

It is difficult to assess whether such product works as intended or not. But, despite the less than average build quality, it felt comfortable, even after 30 minutes of wearing it. It fits tight thanks to its soft rubber construction. It allows almost natural breathing, but smells strongly to rubber material. Since all labels are in Chinese, namely the labels on the detachable filters, is difficult to tell for sure for which kind of atmospheres this mask is adequate. Therefore, I wouldn't recommend the use of this mask for any other thing than filtering dust, which is what I'll be using it to.

This dial will do the job, but it is fair to say, "you get what you pay for". The dial is very small and difficult to read and the build quality feels cheap.

Delivered quickly (from warehouse in FR). Excellent quality, especially in this price range. Mostly pre-assembled, only few parts need to be put together in this kit. The product was well packaged with soft padding and the parts look of good quality indeed. The instructions are clear for the most part. Some assembling steps should be a little bit better explained if this is to be assembled by someone without previous experience. In particular, the adjustment of the pressure of the pulleys, although very easy to perform, was not clearly explained. Related to that issue, the pressure on the pulleys on the pre-assembled Y-axis was too high. After adjusting the movement of the axis was very smooth and without play. Despite these remarks, the entire assembling process took less than one 1 hour and was easy to follow. The different screws and nuts were packed in clearly labeled bags, which helped a lot. All the required tools where included in the package. First impressions after turning it on were very positive: nearly silent axis movement, intuitive color touch screen interface, and hassle free bed leveling. The interface is intuitive and provides tools to test all functions of the printer. At the time of writing this review I have not yet printed.

The product functionality is great and it's much better value for money than the equivalent products sold without housing. However one aspect is disappointing: the battery does't last very long even if the product is not being used. Maybe it my unit has a defective battery, or maybe the product is always draining the battery even when not in use. In either case, the product must be always kept in the charger if one wants to be able to use it when needed.
