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:a 1997 sebring JXI and the fog lights didnt work. Got new bulbs, replaced 'em and didnt work. Checked and all fuses are fine what is are some common 90's sebring electric problems
There are really only three options left and I would check them in this order: The fog light relay (most likely underhood) The fog light switch The wiring between all components A volt/ohm meter can test all of the above.
Q:I was wondering if anybody could tell me how to find a short circuit in my car because it is draining my battery. The car has all electrical components brand new such as the alternator, starter, battery, voltage regulator and relay. The car is not blowing any fuses but drains the battery overnight. Can anybody tell me how to test for a short circuit? Thanks to everybody that helps.
Unhook the battery ground cable and hook up a voltmeter between the cable and battery. Start pulling fuses until the meter drops below 11 volts. This will tell you which circuit is drawing power. Check out all items on this fuse. The most common places to look are the lights in the trunk, glove box and under the hood.
Q:a 75kv 750mA fuse has blown in my micowave (sanyo em d953)do these blow because of the age of the machine or is there another reason
Did you know (true story) when microwaves first came out the companies selling them employed a scientist to do a report on them to see if they were safe. He tested them thoroughly, and announced that yes, they were safe. Then went home and threw out his microwave. This is a true story.
Q:I have checked every single fuse under the hood and under the steering wheel. Still no radio, clock, or dome lights.
Double check the fuses tor the dome light and cigar lighter, its easy to miss a bad fuse If you have a test light or DVOM (multi meter) use it to check both sides of the fuse for power, obviously an open in the fuse is going to cause one side of it to have power and not the other. You will need these tool to verify the fuse is getting power, check the condition of the fuse, and trace the power to the individual components on that circuit. For backyard mechanics, Harbor Freight has these tool for the $5-10 range that work great for occasional use. Good luck man! If you need any further help with open / short diagnosis just let me know.
Q:I have a 240 watt car amp and every time i put my ground wire in the fuse blows and the only other thing i have hooked up is my power no speakers or remote just the ground and power can someone please help me?

Q:i just upgraded from a p200-2 to a t500.1 they are rockford amps. i had the p200 powering two alpine type r's. abc warehouse told me i was severely underpowering them and continuing to do so would ruin them. they hooked up 4 gauge wiring but kept my fuse and fuse holder. i plan on buying the bigger fuse holder and the 200 watt or voltage (idk how they measure them) fuse for the amp but i was wondering if i could use it for a couple weeks until i have the time and 40 bucks to buy and install these parts. they also told me that my jvc cd player doesnt have the right input for subs even tho ive been there 3 times with that same cd player and they never told me this. heres a list of my stuff. 2 alpine type r 12 inch subs in a q-logic ported box. a jvc cd player ( i payed round 150) a rockford t500.1 amp, 4 gauge power and ground wires, 8 guage rcas, and remote wire, a fuse holder that came with a 8 gauge amp wiring kit and a 80 watt fuse. what would you do next if you were in my situation?
He is correct, you cannot damage a sub by underpowering them, that is just a myth. You can damage them however by going more then 10% over the rated wattage. Your head unit doesn't effect your subs it only effects the speakers wired to it. Since you upgraded and you only have an 80amp fuse, you will need a bigger one. You need one that matches somwhat close to your fuses on your amp, I am running a 100amp fuse on a 750w amp and im sure your amp is much larger.
Q:I recently blew a 25a fuse in a mini fridge which was soldered in. I currently don't have a 25a fuse to replace it with so what would happen if I used a 30a fuse instead?
You need to go get the correct amp fuse for the appliance, If you put a bigger amp in then it is designed to take if something starts to go out in the appliance it wont blow the fuse at the time it is suppose to and could ruin the appliance or catch on fire. Please do not use the larger amp.
Q:i already had a 600w rms mono amp for my bass and a 1.0 Farad Digital Car Audio Capacitor, and it was fine for a year , a few week ago i install a 200w rms American pro amp to run my door speaker and it happen every morning i had to jump my truck, i unplug that new amp for a week and everything went back to normal during that week i took truck to dealer for a 250 point inspection everything was fine ,i saw that my battery was a cheap factory battery so i got a optima battery i rewire everything 0 gauge front to back and 4 gauge on back to wire both amp and cap.after all my truck die agan , had to jump this morning
It may seem obvious to you already, but there's an issue with your American pro amp. It sounds like the amp is staying on all the time. Make sure the REM input only has +12volt power when the key is turned. The remote lead from the HU is supposed to switch the amplifier on, but if you've got a stock radio you might want to tap a fuse in your fuse box to get switched power. If it's turning off like it's supposed to, it has an internal fault making it a constant drain on your battery.
Q:I have a variac transformer rated at 7.5 amps but the fuse burned out. I want to increase the rating to 20 amps, can I do this by replacing the fuse with a 20 amp fuse?
The weakest link in a Variac is the carbon commutator wiper (the part that rotates on the exposed adjustable winding). While the Variac may tolerate a 20 amp fuse rating for a short period of time - the wiper will soon burn out and become intermittent or open due to excessive current. Try a 7.5 amp slo-blow fuse instead of the conventional fuse. This will give the variac more surge protection and provide the same capacity as a higher rated fuse for a short period of time and still prevent permanent damage to the wiper/winding components.
