Product Description:


Three phase the meters are used to measure active or reactive energy of three-phase circuit with refrence frequency 50Hz or 60Hz. DT862、DT864、DS862、DS864 are three-phase active meters,DX862、DX864、DX865、DX863 are three-phase reactive meters.

Technical parameters

1、Meters conform to GB/T 15283-1994 and GB/T 15282-1994 standards (IEC521-1998).
2、Meters can be made into types: direct wiring and CT/PT wiring;
3、Can be made into special meters according customer’s requirements (different frequeny, voltage, current specifications etc.)
4、Power consumption:active power consumption of voltage circuit less than 2W(under reference conditions)
5、Dielectric properties:1.2/50µs wave,peak value:6kV, no damage permitted under 10 times test. meter can withstand 2kV(circuit to earth, under 45~65Hz,1 minute)。

Q:Would it be safe to put 4A fuses in an audio receiver that takes 2A fuses?
If the reciever powers-up without these fuses, they are there to protect the speakers more so than the reciever. As the other fellow mentioned, however they do protect the reciever amp outputs in case of a speaker wire short. Once the speakers are connected this is fairly rare though it can happen while connecting the speakers - prudence dictates connecting the speakers with the amp off. If you use a fuse with a higher rating, and either turn the amp up too loud or (depending on the amp design) an output device fails, you will be more likely to blow up the speakers than the amp. If you don't mind this risk and don't intend to play the system very loud, it is probably safe; just be aware that your speakers are at some risk
Q:Rear AC not working, 2000 Chevy Tahoe?
Should be in the blower itself, not the actuators. What you can do is get a short finder so you dont have to keep replacing 30A fuses, but unplug the relay in the back for the blower motor see if the short is before the rear HVac or inside the rear HVAC. If it doesnt blow then insert the relay unplug the blower itself see if it is the problem. Maybe it or a short in the wiring somewhere
Q:can I replace 4 amp 250V FUSE for 5 amp 250 V. FUSE manual says 4amp?
yes you can, 1 amp wont hurt it at all. just do it in a static free area.
Q:My fuse blows every time I turn on my (optimus stereo amplifier mpa 250)?
That fuse collection is saving your amp. You've got a short circuit in it somewhere. Needs checking out. Take the cover off and look for burn marks in the mains-in part and on the circuit boards. You might have a burnt-out resister or capacitor somewhere or a badly screwed up transister especially in the output stage. Power transisters can get hot. They have heat sinks they get bolted to and heat paste to make a good junction so the heat gets transfered better, Check the wires all round for molten or burnt insulation. Sometimes it's just dust that builds up inside that causes the problem especially in vintage amps that may have running twenty years without a clean out. Sometimes it's insects that get burned to a cinder and form a carbon bridge between components. Carbon is a good conductor and then you get a short circuit. Make sure the plug is out of the wall socket and give the amp a brush out with a vacuum cleaner nozzle held close to the brush. A 1-2 inch house painting brush works fine.
Q:They say that every atom in our body was once part of a star?
When the big bang cooled to the point where matter could form, the whole universe was pretty much 100% hydrogen (and empty space). Every atom in the universe which isn't hydrogen was generated in the hearts of stars formed by clumps of hydrogen which coalesced into nuclear fusion reactors and generated new heavier atoms.
Q:Which device is capable of transforming mechanical energy into electrical energy? * please help?
Generator. Uses fuel that burns and create motion of a machine called a Prime Mover. The Prime Mover then drives a coil inside a generator.The coil cuts through Magnetic lines of forces around another coil.This induces a voltage on the coil as it rotates on the shaft of the prime mover. This voltage forms the electrical energy that is taken from the generator. This all depends on the size generator. may be too much for you based on the question, but hope it works!
Q:How to install interior neons to a fuse?
your car dont have power seats but if you look under ye seats you should be able to find the conectors for the power seats as the car is wired an then the seats are put in at the factory so if its got power seats they plug them in if not then they just leave the plug or tuk it under the carpet,you will have to find out which is live and so on and make sure u use the right amp fuse,but it should be pretty easy to do.the other way is buy some think at pound land with a cigarette lighter connector an wire it up that way just hide the wire under ye carpet then plug them in an when u get sik ov them pull it out
Q:How does a fuse blow in a ballast?
A surge is not going to blow a fuse IN a ballast. A fuse will blow when there is too much current flowing - which might be a loose wire touching ground or two wires shorting. If the fuse is in the fuse box then something else being on the circuit might blow the fuse.
Q:How do the components of the cell work together to produce the secretion of functional proteins?
Beginning in the nucleus, DNA is wound tightly into chromatin to allow it all to fit. When a segment of DNA is needed, the chromatin unwinds, with the help of enzymes and proteins, revealing a section of nucleolar DNA. This DNA is then transcribed into messenger RNA. mRNA moves from the nucleus to the cytoplasm, where is it translated into an immature peptide/protein by ribosomes and the translational apparatus. This protein leaves the ribosome and enters the endoplasmic reticulum. It is important to note, some ribosomes are located on the endoplasmic reticulum, making it easier for the protein to move there, while others are free floating in the cytoplasm. Once inside the endoplasmic reticulum, the protein is modified. It can be processed in many ways, from the addition of signal tags and peptides, to proper folding and orientation. The mature protein then moves into the golgi apparatus, where is is packaged into a small vesicle. This vesicle carries the protein to the inside of the cell membrane, where it fuses and through exocytosis, or in some cases channel mediated transfer, allows the protein to be released into the extracellular matrix.
Q:Motorcycle wont turn on.?
james is right you MUST have blown a fuse or two and a blown fuse will keep electricity from getting to any thing and everything so double check all of your fuses and uhhh do something about your terminals i am hoping the reason you mixxed them up is because they arent marked and so you should mark them so you dont take a chance of doing even more damage
