Product Description:

Brief

It is used in the AC power distribution system terminal with the 1 kV voltage or more to increase power factor,to reduce ciruit loss,to improve the output of the transformer and to make the motor economically operated.It is used paralleled with the motor and the inductive load to automatically tracking compensate to the frequency factor.TBBW2 merged measurement and Compensation funceions into 1,it is the best choice for low-voltage side compensation of tranformers.
Operating standard:IEC439,GB7251-97,JB7113-93.


Main features

a、Novel in structure,light in weight.
b、Applies the intelligent reactive compensation controller, has complete functions and good performance.The compensation type can be transformed at liberty between the automate and the manual.
c、Operation can be directly inspected by the displayed number of the frequency factor.
d、It is safely used and protection for over voltage.It will automatically restore to operate if the voltage is normal.

Q:Where can I buy fuses for an old rotel amplifier. It's 20 years old but in great condition.?
I repair these - it is never just the fuse! I urge you to not attempt to just replace the fuse. Fuses do not go out due to age, they blow to protect other components from further damage and/or fire (no, I am not kidding). The amplifier requires service by a qualified technician. There are no user replaceable parts inside. Those Rotels were good units and worth the repair. Your best bet will be a stereo/home theater store that does repairs, although you may find a TV repair shop that has an tech that knows vintage audio. Now put that screw-driver away before you hurt yourself.
Q:what could cause the fuses in my car to short out?
its probably some wires that are touching the frame of the car or something, causing it to short out.
Q:What wire kit to buy for my car amp?
a lot of the 0 awg wiring kit comes with either 100 or 150 ANL fuse, because is cheapest one to give it out for free. For real, some of the expensive wiring kit might come with something like 250 to 300 amp fuse, I would just get the cheapest wiring kit but got be at 0/1 awg wire, and replace the fuse itself.
Q:What was the first electronic device in the history of mankind.?
Wow, very demanding for someone who needs a favor. The compass. Really. It uses electromagnetic waves to point north. The ability to recognize this and build a device that can use it was the first electronic device.
Q:I blew a 60a and 80a agu fuse should i get 100a or 125a?
Find the short before you trash your gear and start a fire.
Q:What do these circuit components do?
Switch- Turns the circuit on. Cell- Basically, a single battery Battery- A pair of cells. Diode- A semiconductor device with two terminals, typically allowing the flow of current in one direction only. Resistor-A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit. Variable Resistor- A variable resistor is a potentiometer with only two connecting wires instead of three. Lamp- A device for giving light, either one consisting of an electric bulb, together with its holder and shade or cover, or one burning gas or a liquid fuel. Fuse-an electrical device that can interrupt the flow of electrical current when it is overloaded. Voltmeter- A device that measures Volts. Ammeter- A device that measures Amps. Thermistor-A resistor whose resistance varies as a function of temperature. Thermistors are used in electrical devices such as thermometers and thermostats that measure, monitor, or regulate temperature. I.D.R- Interval data recorder.
Q:88 300ZX, why did my stereo, pwr mirrors, pwr mirrors defog switch and my intermittent wiper lose power?
Vasek, you could bend backward previously an vertical reflect along with your lettered Tshirt (or placed a e book in the front of it) and nonetheless the textual content will be flipped horizontally. have you ever considered why in a concave (round )reflect (at the same time with a spoon) up is down, ideal is left and left is ideal. Edit: expensive Vasec, Trak's answer inspired me and has made me chuckle, a lot for conservation or vertical axis. yet i'm positive that Scythian meant properly by pointing so that you could target to forget all preconcieved understanding of categorized guidelines and picture out of the field. even with the reality that the way he has expressed it would want to seem slightly harsh. Use your mind's eye, make your reflect slowly become concave, and flat back, and concave back. take it in outer area in case you opt for to, there are not any limits in imaginary land! imagine that you're one unmarried asymetrical letter in area searching on the reflect, rotate the reflect about its middle in an x,y and z axis even as the reflect continues to be in a in no way ending round mutation transition from flat to round to flat Oops, I meant rotate your self (as an asymetrical letter) in the front of the ever replacing reflect. imagine that you will see the reflect photo from each perspective in which you rotate. sturdy success! have exciting) Sleep properly xx
Q:sony projection kp46xbr35 pic is shaped like a bowl?
If it had bad fuses the cross would be misaligned. If you move the red and blue up and down and the whole picture moves (the red and blue part) then I suspect a vertical deflection problem. This could be the output ic, the jungle ic, or associated component and connections. The only way to find out is with an 0-scope in a shop.
Q:Bad Battery jumping for a Toyota Tercel 99. What fuse I should check?
toyotas have a master fuse(100 amp) it is in you under hood fuse box.make sure you didn`t melt any bat cables.also you may have fried your pcm good luck
Q:just bought a new car 89' 190E Benz i cant find the fuse box any where in my car?
There are two locations: 1. there is a fuse box under the hood. The top right side, in front of the driver, just look for broken or fried metal on the fuses. 2. Go on-line and print the schematic of the fuses which are disbursed throughout the engine. I am not a mechanic, but an Computer IT Tech, so I immediately checked the internet and found everything I need to know about my 889 190E Benz, it is an amazing car, it runs better than some newer non-German cars.
