How big does a voltage regulator need to be installed at home? Does anyone know?

The voltage regulator looks at the power (greater than the total power of the lighting you are using) and the rated voltage of your lamp, and it's OK. For example, if your smart lighting specification is 24VAC 55W, and you can install two lights (the specific number is up to you), then you have to choose 220V to 24V.

Recommend one to you that can meet your requirements.

It depends on what kind of appliance you use. If it is an ordinary household appliance, you only need to re-walk a large wire with an air switch wire and a large cross-section.

Hope my advice can help you!

May you be in good health!

The voltage regulator needs to be installed when the home power supply is unstable, and the selected power should be the sum of the power of all household appliances, but due to the premise that the input voltage is unstable, it is actually difficult to support a large power, and it is recommended to use it below 3000 watts. If you want to use more power, you should find a way to stabilize the input voltage.

This needs to see how much electricity power you have at home, for example, the air conditioner is 2 dry watts, the washing machine, the water heater is 2 kilowatts, and the other 1 kilowatt, so it takes about 5 dry watts, if it is not used at the same time, it can be lower, and I don't know your local power supply situation, now the power supply of the national grid is very normal, unlike the early years of voltage instability, there is no need for the family to be equipped with a voltage regulator, and now the power supply of household appliances is complete with a complete protection circuit, and the range of voltage fluctuations is not strict, so there is generally no need to install a voltage regulator!

The power of the voltage regulator shall not exceed the output capacity, like the air conditioner and refrigerator at home The starting current is very large, the output capacity of the voltage regulator should be 2-4 times the load power, you can buy according to your full power, the electricity at home is generally single-phase, the zero line and the live wire are connected to the input, and the output is also the zero line and the output live wire is connected to the electrical appliance.

Generally, the voltage regulator is installed behind the main switch, but it should be noted that the voltage regulator can withstand a few amperes (a).

If there are many household appliances, it is recommended to find an expert to install them to avoid danger in the future.

Agree with the upstairs, but there are not many good regulators at home now. Don't use it if there's nothing to do... Be careful not to reverse the wiring.

If it is in the community, it is best to install it in the upstream of household appliances and computers to ensure that the voltage is the first household voltage regulator: it is, its role is to stabilize the power supply voltage that fluctuates greatly and does not meet the requirements of electrical equipment within its set value range, so that various circuits or electrical equipment can work normally under the rated working voltage.

A 220V voltage regulator for home use. The voltage regulator is composed of a voltage regulating circuit, a control circuit, and a servo motor. When the input voltage or load changes, the control circuit sampling, compares, amplifies, and then drives the servo motor to rotate, so that the position of the carbon brush of the voltage regulator changes, and the coil turns ratio is automatically adjusted, so as to keep the output voltage stable.

The function of the voltage regulator is to stabilize the power supply voltage required by the fluctuating and unsuitable electrical equipment within its set value range, so that various circuits or electrical equipment can work normally under the rated working voltage.

It is not necessary to use a voltage regulator for all electrical appliances, the key is to equip air conditioners, refrigerators and computers with voltage regulators.

The power of the voltage regulator should be three times the power of the electrical applianceIt can be configured with high power, driven together, or configured separately according to electrical appliances, such as a refrigerator and an air conditioner.

Security Matters:

When the regulated power supply is powered on, do not disassemble the stabilized power supply or pull the input and output cables of the stabilized power supply to prevent electric shock or other electrical safety accidents.

The input and output connections of the regulated power supply must be reasonably arranged to prevent trampling and wearing, resulting in leakage accidents.

The stabilized power supply must be reliably grounded, and the user shall be responsible for the electric shock or personal injury caused by the operation without the grounding wire.

The input and output connections of the regulated power supply should be checked regularly to avoid loosening or falling off, which will affect the normal use and electrical safety of the regulated power supply.

The connecting line of the voltage regulator must be equipped with a connection line that can carry sufficient current capacity as specified.

The voltage regulator should be handled with care, and violent vibration should be avoided when working;

Ensure that the carbon brush spring of the voltage regulator has enough pressure to avoid the carbon brush and the coil contact surface from flashing;

Non-professionals, please do not disassemble the regulated power supply or repair the regulated power supply.

Loads of power multiples.

In the environment of large inductive and capacitive loads (such as motors and computers), the starting current of the load should be considered to be particularly large (up to 5 or 8 times of the rated current), so the voltage regulator capacity should be selected as a time of the load power.

The AC regulated power supply is based on the output apparent power (kVA) as the nominal rated capacity, and the load is generally not purely resistive, that is, the power factor COS ≠1, and the actual active power that the regulator can output KW = capacity (kVA) COS.

Therefore, in the actual selection, the regulated power supply should be reasonably selected according to the specific conditions such as rated power, power factor and load type of the electrical equipment, and the output power should be left with an appropriate margin, especially when the impact load is selected, the margin should be larger.

The power of the voltage regulator should be three times the total power of the electrical appliance. However, the water heater is more powerful and generally does not need to use a voltage regulator.

The 10kV voltage regulator can drive almost all electrical appliances, but the voltage regulator is best to buy servo voltage regulator, the voltage stabilization accuracy is high, but the cost is higher; And don't buy relay regulators, the temperature accuracy is poor, the voltage changes too much, but the cost is lower.

Desktops don't need to be regulated to work properly.

A small air conditioner, a water heater, a refrigerator, an induction cooker, in the case of different simultaneous use, there is a 3--5kv voltage regulator. Automatic voltage regulator: 3kV is about 1500 yuan.

Manual 3kv600 or so. The brand, it doesn't matter as long as it's **.

Have fun!

The household type with 10kva is more suitable, there are air conditioners, washing machines, refrigerators These are all inductive loads, which need to be magnified three times to match. There are also induction cooktops. If used at the same time, the regulator capacity is too small and it is easy to overload and affect the service life!!

10kv means voltage is 10,000 volts and capacity unit refers to kva

Is it necessary to have a voltage regulator for your household appliances? Find a professional to test the voltage fluctuation and then determine.

Requires 5kVA size.
