Product Description:


DT607、DS607 series three-phase inductance type meteres are used to measure active energy with reference frequency 50Hz. features: low power consumption, high stability, long life.

Type and meaning
Normal operation and installation conditions

1、Specified operation temperature range:-25℃~55℃;
2、Limit operation temperature range:-40℃~70℃;
3、Relative humidity : less than 85%(ambient temperature is 23℃);
4、No corrosive gas and dust-proof, no mildew, no insects.

Construction features

1、Rotating parts use long life technics:a、use oxidation-proof magnet bearing, no abrasion. b、fixed bearing on and under rotating axis(imported from german) c、use high strength and high rigidity material for up-down bearing pin; d、rotating axis and worm in a same axis to ensure long life operation(more than 25 years).
2、Electranagnetic system uses new construction: voltage and current coil are all fixed on a iron frame to ensure stability.
3、Braking components use new construction and high magnet-accumulating material( LNG37 permanent magnet alloy) to ensure stability;
4、Use excellent material for voltage coil(can withstand Uimp more than 6kV;
5、High accuracy of register to ensure long life.
6、Base and terminal block use high insulation and burning-proof material;
7、Use polycarbonate as cover to ensure good transparent effect and high strength.

Main technical parameters

1、Conform to GB/T 15283-1994 and IEC 521-1988 standards;
2、Class index:2;
3、Reference voltage:3×220V / 380V、3×380V、3×100V;
4、Ib and Imax:3×1.5(6)A、3×3(6)A、3×5(20)A、3×10(40)A、3×10(60)A、
5、Power consumption:less than 1.5W and 2VA under reference voltage,current and frequency;
6、Start-up: under the condition of the referenced pressure, referenced 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.
7、Potential action: the ammeter's rotor turns without exceeding one cycle when its line has no electric current and the pressure is 80%~110%of the reference.
8、Dielectic properties conform to GB / T 15283-1994.

Q:What size fuse for these amps?
always place an in line fuse the the amp wiring ; as close to the battery as possible . consider this if the amp wire gets pinched or drilled though then a short to ground exists . you want the in line fuse at the battery to blow so the wire does not heat up and possibly burn your car down. Add the total current requirements and use that size fuse and appropriate holder; in your case 100 A . Ps it is extremely important to have an in line fuse at or very near the battery.
Q:2002 GMC Envoy with no power to the rear tailgate.?
in side of fuse cover should show full lay out of same look on inside of cover plate
Q:I've blown a fuse in my computer power supply. Help ?
The blown fuse is what protects the rest of your PC from power surges etc., and that's exactly why it blows. If you can replace the fuse do that and you should be all set. If not then you'll need to replace the power supply. Hope this helps.
Q:My car won't start!!!?
The ignition fuel and starter are all on the same circuit?? Seems odd, but possible I guess. Your going to have to get an amperage draw test done on the individual components of the system and see which one is drawing enough amps to melt the fuse. Could be the components, the wiring (not likely) or the control module (rare). Also could be a short to ground or short to power. Sounds confusing but I bet it's faulty internal starter windings causing the problem. Have the starter removed and professionally tested by a reputable auto electric shop not a parts guy that thinks he's a mechanic. Also if it's a manual transmission car try parking it on hills and roll starting it to verify the problem if this is possible.
Q:what electronic component is this?
Use a volt/ohm meter to test the fuse. Connect leads to each side of the fuse. With power off, measure ohms. Anything other than zero, you need to replace the fuse. or With power on, measure volts. Anything other than zero, you need to replace the fuse.
Q:General Physics question about electrical components?
hmm - the fuse resistance was very low, the diode was infinite 'cos it didn't conduct - it would have done if you reversed the polarity ( turned it round!). This was an experiment - you do not ask what they are supposed to read, it's your job to find out by measuring.!!! That's Physics, not Criminology! The resistor could be out of tolerance, but so what? Just measure it's value as it is now.
Q:Transmission Fluid Change?
For a healthy auto transmission system, change the ATF fluid including the strainer assembly every 40,000 km. This will preclude wear and tear of the internal subassemblies.
Q:What are the components for a 12VDC Circuit if using a 12VDC 90 Ah Battery Source? Read more below.?
A circuit to do what? 12 volts could power any kind of circuit, from a simple light bulb connected to a battery, to an entire car with complex audio and security systems. What are you talking about specifically?
Q:How does a fuse blow in a ballast?
The main component in the ballast is a large inductor, and if a turn gets shorted, it will draw high current. Suspect the ballast. Also, with a coffee maker and a microwave, the total current could be too high for the circuit breaker.
Q:Appliance guys: I have a Roper electric dryer RES7648EQ2-it just stopped tumbling?
Okay. Always something new to think about, ehhh? The belt wrapped around your dryer drum is actually supposed to work like a serpentine belt in your car. It goes around the pulley on the motor, which moves it around a tensioning pulley and then around your drum. The motor turns the pulley that turns the belt that turns the drum. It may just be tight around the drum and not melted to it. It could melt to it if it got hot from friction, melted and, then fused to the drum as it cooled. That assumes your drum stopped turning while the belt kept sliding. Your dryer should have a lower front panel that can be removed to reveal the pulleys and motor. UNPLUG the dryer if you take off the front cover. Can you turn the drum by hand? Look at the wheels and pulleys when you have the cover off and are attempting to move the drum. If you want moreyou can remove the belt from the tensioning wheel by bending the spring metal arm it is on and then, you can slide the belt off of it to relaease the tension. Now try moving your drum by hand---power is still unplugged. If it moves,take the belt off (if it is stuck to the drum) and get a new belt. If it is not stuck to the drum and the drum doesn't move leave the belt alone, and you have to find where it is stuck from rolling around. Maybe the support roller wheels are stuck. Now plug in the dryer and push start. The motor should be visible from the front of the machine, and you should see it moving, the motor, not the drum If it doesn't run then you are talking new motor. Most all parts, wheels belts motors are available on OKorder for not too much. That is all there is to the moving drum of the dryermotor drum belt rollers tension wheel
