DC Cable Size Calculator

DC cable size calculator is an important part of the solar panel array system. Before using the DC cable should pay attention to some factor calculator such as the possibility of excessive heat.

Because if the wire emitting high heat can cause loss of energy is wasted, or worse can result in a fire on the system.

To avoid this, before installing the DC cable size calculator should consider the worst had happened.

Hotel Electrical Installation

Hotel Electrical Installation - Electric power is the main thing that is needed in service industries such as hotels, because many devices which operate by electricity. Electricity is very important for every human life, but also can pose a hazard in the event of an accident. Therefore, in designing electrical installations for hotels also require special planning.

Hotel electrical installation can be said safe if it meets the standards set in international scale. Many things need to be calculated when the electrical installation, for example about the grounding, the type of cable used, the shape of the hotel building, and much more.

The important thing to take precedence on the hotel electrical installation is the safety systems on emergency time. Electrical installation systems must not harm humans, have enough power to supply all parts of the hotel.

If all standards can already be implemented, the hotel electrical installation can be passed verification.

Repairing Mobile Phone Charger

Hah, my cell phone charger is damaged, want to buy a new charger no money :P. Repairing mobile phone charger does not seem very important, because besides the price is relatively cheap also makes components that just a little lazy to unpack. But it turned out pretty well if you have damage charger then we fix itself, can save our money.

In fact, lately I got a lot of mobile phone chargers damaged, initially only my friends who ask for help repair a damaged charger, but then they tell each other, eventually a lot of friend swho ask for my service service: P

Well, what components are often damage in this HP charger? If I found many of his fuse-resistor components are damaged. This component is the location of the cable going into the diode AC power supply, and also found a dead diode on the output voltage.

Type Of Oscillator IC

Type of  oscillator IC on the monitor and the TV there are many, but as I know only a few species only. For understanding, IC oscillator is one of the electronic component that functions as a generator of oscillations and waves and video signals as a trigger to generate a horizontal high voltage output.

Type of IC oscillator in the monitor there are several kinds, namely:
1. TDA 9111 = TDA 9113
2. TDA 9112 = TDA 9115
3. TDA 9113
4. TDA 9115
5. TDA 9116 = TDA 9111 , TDA 9113
6. TDA 4841
7. TDA 4856 = TDA 4859 
8. TDA 4859
9. STV 6886
10. STV 6888 = TDA 9111, TDA 9113, TDA 9116
11. There again, but I forgot .. : D

Oscillator IC above is that in use on the monitor brand Samsung, Philips, Dell, and IBM. Understandably I do much of that brand monitors, so for another brand that has not been collected papers. For the time being until a short post here today, greetings, may your day fun .. : D
