Looking inside helps it says 7.5vdc 1a I tried it with a precision power supply and it works on that voltage. Wish they would remember to put that on the outside as well.

SOURCE: Gigafast ethernet won't let my Xbox connect to live

You might open this ports to the Gigafast Ethernet router :

TCP 80, 3074 and 53

UDP 88, 3074 and 53

Note: You'll needing to open these ports to the virtual server or port forwarding under advance settings of the router.

Yukon 2.5 x50 nvrs tactical night vision rifle scope, works fine but making a strange processing noise when on?


Hello, don't worry about it. It is HV to the image intensifier tube. The battery voltage goes through control circuit then to ccfl inverter (here is were dc voltage is switch on and off and switch dc voltage is step up by toroid coil that has two input and only two out puts). By impulsing the coil with two different switch dc voltage on the input this make the current lag the two different phase voltage by 90 degrees. Here is where the strange noise is coming from. The toroid coil is encased in iron case and if half of this iron case is loose, it makes case vibrate so the noise.


Now, the voltage come out of the toroid coil is switching dc (one could call it AC because that what AC voltage is, it switch between positive to negative) this voltage is about 300 to 900 switching DC voltage. This voltage will be applied to a 1/2 wave voltage multiplier (this voltage multiplier with have anywhere four four stages to 10 stages depend on what the input voltage to multiplier is.

Low the voltage out of the ccfl inverter the more stages the multiplier will have.



Now, the voltage multiplier will double the voltage per stage to need image intensifier tube voltage of 12000 to 45000 volts---DC switching or AC what ever one wants to call it. This voltage will bit you but it doesn't have a lot current associated with it, the current would be in the 10 to 15 ua (micro-amps) 1/10X6 amps.

HOW DO I RECHARGE SPECIFICE CHARGER OR BY COMPUTER


By computer so that you will obtain the specific charger that you need.

plankw,
What laptop is it? Manufacturer name, and Model Number.
(Bottom of laptop)

Also,.....on the Bottom of the laptop is stated the Input, and Output voltage.
Your concern is the input Voltage, not so much about the Amperage.
(V = Voltage, A = Amperage)

Example;
Input: 12V2A (Sometimes printed as 12V~2A)
12 Volts at 2 Amperes.

The AC adapter (Charger) must also have the correct plug to fit the laptop's DC Power Jack.
(DC IN)

Power supply circuit boards,gives only 2.0 volts


OK, what is the input voltage? I will give you a ruff diagram here. (volt in) Vcc--sw's-on/off/IR-control board (microprocessor)---ccfl (cold cathode fluorescent lamp) inverter (changes DC voltage tow switching DC (such as on/off/on/off/on/off but at a much faster pace (20Khz)---toroidal coil (this coil will step the switch DC voltage up to about 1000 to 1500 switch DC volt, then this coil will change the orientation of the voltage to current relationship by shifting the current by 90 degree's where it lag the voltage---this process has some changes on circuit and how it works)----OK, from the ccfl inverter------voltage multiplier (all this some HV capacitors and HV diodes hook up an configuration where each stage will double the voltage that go into... EXAMPLE: 4 stage voltage multiplier for each stage now it double the voltage 1500V input to 1st stage--output to 2nd stage 3000V output to 3rd stage 6000V out put to 4th stage 12000V switching DC, they will also refer to this voltage AC voltage because AC switch to from - negative voltage to + positive voltage.


Like in you case, the two volts from the controller to ccfl. Out put volt from ccfl with be around 2.4 to 2.6 due capacitance discharge, Now this voltage will be divided in the ccfl by two input windings (I am not going to explain this). Now the two input winding will induce voltage to the secondary winding (step up). The output from secondary of toroidal coil will be multi switching to the voltage multiplier. Probably in the neighborhood of 1500 switching volt. How many stages the voltage multiplier has I don't know. The ignitier voltage to the cathode from the multiplier would be around 12000 voltage to get image intensifier tube to fire. stewbison

3-phase recty fier not output voltage 230V 10V


What is the type (input, output, power) of the rectifier.
If controllable - may be the control PCB or thyristor.
If not controllable - 10 V DC instead of 230 V DC is hardly believable.
In this case the rectifier may be OK, but the input - low.
If you have a voltmeter, check the input AC and the output DC if the output has about 200 V AC you may have shortened diode.

I attach my inverter with custom battery cables and it powers up. As soon as I plug in an extension cord (any cord)it starts beeping. I don't even have anything plugged into the other end.


please check the voltage of the battery may be the voltage of battery is low or use the multi meter and check DC volts before conneceting the battery and after conneceting once more check the DC volts it could slove the problem
the beeping sound is due to battery low voltage
what is the DC input of the Inverter check the battery hook up if the inverter is of example DC 24 volts please check what is the input
