DD862 type single-phase inductance AC active energy meters are used to measure active energy loss with frequency 50Hz or 60Hz。 features: new design, resonable construction, high overload, low power consumption, long life , high stablity. the meter is very popular by customers.


Type and meaning
Type and specification
Main technical parameters

1、Meters conform to GB/T 15283 -1994 and IEC 521-1988 standards.
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 frequency, voltage,current specifications etc.).
4、 Start-up: under the condition of the referenced voltage, reference frequency and cosΦ=1, and the load circuit doesn't exceed the 0.5% of the basic circuit, the ammeter's rotor can be started up and constant turning.
5、 Potential action: the ammeter's rotor turns without exceeding one cycle when its line has no electric current and the voltage is 80%~110%of the reference value.
6、Power consumption:active power consumption of voltage circuit less than 2W(under reference conditions).
7、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: I have a 1998 Honda civic stock altenator I want do a 1200 watt amp it says 120 amps fuses and I want do 2 highs amp 1 300 watt and 1 400 watt will I be ok to hook this up
In the short term, probably. Long term - I'd be surprised if that alt lasts 6 mo. At anything over 1/2 volume that alt will basically be maxed out. Under that much stress the amount of heat produced will be extreme. Heat in alternators causes both the electrical components and the mechanical components to wear out quickly.
Q: And my truck still want start without jumping that wire
Always double check fuses. A poor connections could be the problem but I would be suspicious of the wiring. If the wires run under the truck, make sure they aren't damaged from debris or rubbing on other components. Try jumping at the relay +. If it runs while jumped at relay +, then you know its a problem before the relay (ign switch wiring, fuses, etc)
Q: I know it's loose because if I wiggle it the amp turns off. how can I properly adjust this without injurying myself or ruining frying my amp. do I really have to remove the fuse or since it's only the ground can I just untighten the screw on the cap and then slide the wire back in and tighten it back on the ground? thanks.
If its the ground wire that is loose you can just tighten it. It is the positive wires that you have to worry about because you cant have to watch so you don't short it out.
Q: I need to get a ball park idea regarding fixing or replacing the cigarette lighter in my car--- 2005 Hyundai Accent specifically, but curious how much it would cost for any car. It is not a fuse problem--- when I was pulling my phone charger out, it ripped some component out with it (a metal ring and a smaller metal piece). If I try to plug something it, it sparks and caused my GPS unit to reset, etc.
About 5 bucks and 5 minutes
Q: I have a 2000 Ranger I turned it off and it would not start again I have power to head and dome lights, replaced the 50 blade fuse position number 5 in the power management box and it worked for 1 to 2 sec then burnt out again. is it the starter relay, the ignition switch, the starter or something else. anyone have this problem? how did you fix it? any help would be greatly appreciated
a three or a 5 amp fuse would be positive, as long as your heater works once you slot the plug there is not any would desire to purchase a clean one. If the heater is going defective it particularly is going to easily blow the fuse, yet there is not any reason it is going to.
Q: For example:RresistorCCapacitorLinductorVtubeQtransistorIs there a complete list of normal component designations?
May be this will help you: ?A: Assemblies ?B: Transducers / Sensors / Detectors ?C: Capacitors ?D: Storage devices ?E: Miscellaneous ?F: Fuses ?G: Generator, battery pack ?H: Indicators, signaling devices ?J: Connector / connector pin Joining another connector (P) ?K: Relays ?L: Inductors and filters ?M: Motors ?N: Analogue devices ?P: Measuring / test point / connector plug ?Q: Transistors ?R: Resistors ?S: Switches, push buttons, emergency stops and limit switches ?T: Transformers ?U: Integrated circuits, Power converters, DC power supplies ?V: Electron vacuum tubes tubes ?W: Wires, conductors, power, neutral and earthing busses ?X: Terminal strips, terminations, joins ?Y: Solenoids, electrical actuators ?Z: Filters
Q: I have a 1973 vw beetle. My indicators don't work, as well as my fuel gauge and alt and oil lights. The alt or the oil lights don't come even when you turn the ignition. The headlights work so it's not a fuse. Hazard lights still work and show up on the dash. Can you please tell me what it is
Don't discount the fuse idea until you have checked them all, the headlights work off a different circuit. Since you have lost so many functions, check the earth wire between each of the components/lamps. The Beetle uses a brown wire as earth and it is connected to several components before terminating on the bodywork. Is the flasher relay working correctly? they are cheap to replace but new ones look completly different to the original so take a note of which wire goes to each (numbered) connector. This unit too is earthed by means of the clip which fixes it to the body. Please don't attempt to run the car without knowing that the oil pressure light is working The engine will destroy itself in seconds without oil pressure.
Q: I have a 2000 Grand Am GT (3.4l V6), and my power steering has been messing up. I have replaced my rack and pinion, and I have replaced the power steering pump, and it's still not working. I made sure there was no air in the res, when I put the new pump on, and it's still not steering right. The car has an electrical steering assist, and I was wondering, where would the fuse be for that, if there is one?
If it won't steer to the right, you have a broken/loose rack and pinion steering mount or hold down bracket. Have someone turn the wheel as you watch from under the car and you should see it moving around.
Q: I have a Honda cbr600 2009. The battery was running low so I went to recharge it but accidentally switched the poles. There was some smoke and a few sparks from the battery after about a minute. Once I realized what happened I took them off everything was hot. I let it cool off for a few hours then corrected the charge. surprisingly now its fully charged and I haven't noticed any fuses blown and under glow lights connected directly to the battery are working. Except nothing happens when I turn the key.
You ruined your stator I bet.
Q: I have an assignment on 'Electricity in the home'. The part i have to research on is the components of the main eg; main wire, live wire, neutral wire, 3pin plug, fuse, switch.What do these fall under? I cant jus look for main n find these components. I was told its the 'Main Circuit Breaker'. Im lookin for this and non of the components i listed are on the sites. Is there a particular word i have to use. Are there any other components im missing other than the ones listed above?i jus need to write short notes and get some pictures but im not finding any information.
components are: circuit breaker aka MCB circuit breaker box aka distribution panel aka Consumer unit wire of various sizes wire staples outlets switches lights (permanent mounted in ceiling or wall) Parts attached to the appliance, not part of the mains plug wire and the various tools used to put it all together.
