The voltage is unstable, the cat drops the line, what kind of power adapter to change?

Broadband disconnection is a common fault, and the general cause of failure is divided into 1 computer problem (extremely low probability) is caused by poisoning or improper operation. 2. Cat problems (general probability) are repaired or replaced. 3. Poor line transmission quality (extremely high probability), because the problem of ** cable and your indoor line may cause slow network speed and disconnection.

So don't believe what the maintenance staff says the line is normal. If you can't fix it, you keep complaining. 4. The problem of equipment at the end of the bureau (the probability is super low) is that there is a problem in the computer room, and I can't solve it myself.

If the cat's power adapter is broken, you don't need to repair it, just change it to a new adapter at a computer accessories store, or buy a one of the same model online.

The power adapter is generally burned out due to the following reasons:

First, because the quality of the power supply itself is not good, the inside of the power supply is burned out because it cannot bear it when the load is working for a long time.

Second, it is caused by unstable input voltage or high-frequency clutter. Check whether the plug and socket are in poor contact, whether there are high-power or high-frequency electrical appliances around it, etc., and you can also install a voltage regulator or UPS to improve.

Third, the load has a slight short circuit or intermittent short circuit that causes the power supply to be burned out.

Fourth, the aging of the device causes burning, electronic devices have a certain service life, when long-term use, oxidation and performance changes will cause the instability of the overall circuit work, and then lead to damage.

Fifth, poor heat dissipation causes unstable performance and burns, pay attention to the surrounding environment of the power supply needs to be ventilated, leaving a certain amount of heat dissipation space.

Or change to a simple, very cheap one. If the wire is broken, you can connect it yourself, and pay attention to the positive and negative polarity if it is DC.

This, if you ask me like this, I can only answer, if it is broken, fix it, find an electrical appliance store to repair it, if the wire interface or something, you can still repair it, otherwise, change it.

First of all, the reason for the power burnout is not that it is turned on 24 hours a day, and unplugging the power supply when idle will not significantly extend the service life.

Reasonably designed power supplies can be turned on 24 hours a day, and there are many devices that are 24 hours uninterrupted (such as surveillance cameras, ** tape recorders, electronic clocks, etc.), and most of the power supplies they use are ordinary inductive AC DC conversion power supplies.

Many domestic parallel power supplies are false standard power, working under its identified power for a period of time will be seriously heated and burn the coil insulation layer resulting in damage, if your cat is an 18V AC power supply, I am afraid that it is more difficult to match the general one on the market (such as the recorder with the mobile hard disk, etc. nearby can not be bought in a special store online shopping link has been sent to you) to ensure that the output current has sufficient margin, in addition to the general cat is AC power supply, it is not recommended to use DC power supply when the power is insufficient.

If the problem is still (not necessarily the power supply is damaged, but also manifested as the cat often crashes and drops, and the network speed is unstable), it should be the cat's power management chip is damaged, and it is recommended that you change the cat more realistically.

The idea is not realistic.

The adapter often burns out?

It should not be the original configuration, Shanghai Bell's ordinary cat is with 18V AC power supply, and the multi-terminal wireless cat is 12V DC power supply, which eliminates the power supply problem is whether the socket row is loose there, whether the voltage at home is stable, and a stabilized power supply can be installed.

The power supply of the network cable may cause damage to the computer, the gain outweighs the loss, so the thin wire can not be carried, I really want to buy 2 power adapters for 2 power supplies respectively, and then buy some double-core wires, cut and lengthen one of the power supplies, so that whoever uses it plugs in on the line.

Voltage problems, the average cat is not so easy to break.

This power adapter loves to be bad! Isn't it a problem with the voltage there? Our company has used cats for 3 years, and the power adapter has not broken for three years! If you really can't do it, buy a wireless router, transmit a signal, and set a password.

Absolutely original. Hope it helps you, if the voltage is unstable. You can do it in the following way.

This is my personal experience. Now the cat doesn't drop the line. What's ups.

Voltage regulators. Don't buy it. The price is too high.

It works even if you buy it. Doesn't solve the problem. Cats on desktops are not wide-voltage.

The input voltage is generally the rated voltage of 220V

50hz I'll tell you about my own experience. It's the same as you. Just give it to me.

After determining that it is a problem with the voltage. I'll tell you the rest. Go to ** or pat on to buy that kind of switching power supply.

It's a wide range of voltages. The power adapter that comes with the cat is rated at 220V. Up and down at 10%.

If the voltage is too low, it will restart. I was in the same situation as you.

I've been depressed for a long time. After going to ** or patting on the buy that kind of switching power supply. It's the kind with a wide voltage.

The input voltage is between 100V-220V. No matter how low the voltage is, it will not fall below 100V.

It turns out that I have found another way. What power from the chassis 12V to 9V

Do it yourself to change the power adapter that comes with the cat. I thought about it. After all, I didn't do that if I wasn't professional in electrical appliances.

Later, I have been patting and looking for that kind of switching power supply. Didn't find a suitable one. As soon as the inspiration moved, I went to ** to take a look.

Just what you want. My cat is 9v

800mA. 9V is the voltage and 800mA is the current. It's okay if the current is high.

Don't be small. If it's small, it will ruin the cat. I didn't find the 800ma.

I found a 1100mA (15 yuan). I bought a 600mA one (10 yuan) for the router again. Counting the courier fee, it cost a total of 35 yuan.

Haha do big things with little money. If you can't find it on **, you can q me.

1.Buy a wide voltage cat to use, for example, Huawei's MT880 series voltage adaptation range can reach 90-280V, which can generally solve 2Buying a voltage regulator, generally 1kW is enough, and it can be connected to network devices such as computers, broadband modems and even routers.

There's almost no way to do it except buy a voltage regulator, or UPS...

Please use UPS with voltage stabilization function!
