How much does a home voltage regulator cost? Voltage regulator is a device that stabilizes the output voltage. Voltage regulator regulator circuit, control circuit, and servo motor and other components. When the input voltage or load changes, the control circuit for sampling, comparison, amplification, and then drive the servo motor rotation, so that the position of the regulator carbon brushes change, by automatically adjusting the coil turns ratio, so as to maintain the stability of the output voltage. Here to see the details.
First, how much is a home voltage regulator
Home voltage regulators generally use the TSD series can be. Mainly depends on whether it is only with a computer or all the load. If it is a computer with a TSD-500VA will be enough. More than a hundred dollars, if you take all the load. It is better to match a 5000VA. Six hundred dollars or so!
Two, the role of the voltage regulator
With the rapid progress of society, the use of electricity equipment is increasing day by day. But the aging of power transmission and distribution facilities and the development of lagging behind, as well as poorly designed and insufficient power supply and other reasons resulting in the end of the user's voltage is too low, while the head of the line users are often high voltage, the power equipment, especially on the voltage requirements of the strict high-tech and precision equipment, unique as an untimely bomb. The utility system as a public **** power grid, connected to thousands of various loads, some of the larger inductive, capacitive, switching power supply and other loads not only from the grid to obtain electricity, but also in turn on the grid itself, deterioration of the power grid or local power supply quality of the grid, resulting in utility voltage waveform distortion or frequency drift. In addition unexpected natural and man-made accidents, such as load voltage overload, earthquake, lightning, transmission and transformation system disconnection or short circuit, will jeopardize the normal supply of electricity, thus affecting the normal work of the load.
Unstable voltage can cause fatal injury or malfunction of the equipment, affecting the production, resulting in delayed delivery, quality instability and other aspects of the loss. At the same time accelerate the aging of the equipment, affecting the service life or even burn accessories, so that owners face the need to repair the troubled or short-term need to update the equipment, a waste of resources; serious or even a security incident, resulting in incalculable losses.
So the use of voltage stabilizers, power equipment, especially on the voltage requirements of strict high-tech and precision equipment is essential.

According to the above indicators, Tieta CWY parameter regulator used to match the computer is other regulators can not be compared,? A computer with 500VA parameter regulator is enough, the price of 1000-1200 yuan. The price is 1,000-1,200 yuan, including freight.
Fourth, attention:
Daily attention
1?, avoid violent vibration, prevent corrosive gases and liquids into the flow, to prevent irrigation and placed in a Do not cover the fabric to prevent ventilation and heat dissipation.
2?, please use the three plug (with grounding) socket, machine grounding screws to be properly grounded, otherwise with a stylus to measure the chassis will have a charged phenomenon, which is due to the distribution of capacitance induced electricity caused by the normal phenomenon, can be eliminated through the grounding line. If the case of serious leakage, measured insulation resistance is less than 2MΩ, may be the insulation layer has been damp or line and the case of short circuit, should be identified to eliminate the cause of the problem before use.
3?, 0.5? ~? 1.5KVA? small power regulator for overcurrent short-circuit protection fuse, 2? ~? 40KVA regulator DZ47 circuit breaker for overcurrent, short-circuit protection, such as the fuse is often melted or circuit breaker often tripped, you should check whether the power is too large.
4?, when the output voltage exceeds the protection value (factory phase voltage protection value adjusted to 250V ± 5V), voltage regulator automatic protection, cut off the output voltage of the regulator, while the over-voltage indicator is on, the user should immediately shut down to check the grid voltage or voltage regulator. If the regulator occurs automatically cut off (with input no output), you should check whether the utility voltage is higher than 28OV. if lower than 280V? you should check whether the regulator is faulty. To identify the cause before use.
5?, if the regulator output voltage deviation from 220V? more, please adjust the potentiometer on the control board to the output voltage is normal (the input voltage is not up to the regulator range can not be adjusted).
6?, when the utility voltage is often in the regulator input voltage lower limit (<150v) or upper limit (>260V)? When limit microswitch is often touched, easy to control failure. At this time, the regulator can not regulate the voltage or can only be adjusted high (or can only be adjusted low), you should first check the microswitch is damaged.
7? Please keep the inside of the machine clean, dust will hinder the rotation of the gear, affecting the output voltage accuracy. Please clean and maintain the coil contact surface in time. If the carbon brushes are worn out, the pressure should be adjusted to prevent the carbon brushes and coil contact surface from jumping. Replace the carbon brushes when the length of the brush is less than 2mm. When the coil plane jumps fire and is burnt black, it should be polished by fine sandpaper.
The three-phase voltage regulator input must be connected to the zero (center) wire, otherwise the regulator will not load properly and damage will occur to the regulator and to the electrical equipment. Do not use the ground line instead of the zero line (but the zero ground line can be connected in parallel), and the zero line must not be connected to the fuse.
9?, regulator output voltage is lower than the rated voltage (220V? or three-phase 380V), should check whether the input voltage is too low. When the no-load to the rated voltage and load output below the rated voltage, this is due to the input line load surface is too small, or load side more than the rated capacity of the regulator range, the load line voltage drop is too large, the use of the input voltage is lower than the lower limit of the regulator range of regulation, this time should be replaced with a thicker input wire or increase the capacity of the product.
10?, when a single load power (such as air conditioning, etc.), and input line is longer, the load surface is not enough, the load works when the voltage is seriously reduced, may use the load is difficult to start; when the load is working and temporary shutdown, easy to output instantaneous over-voltage outages, such as the occurrence of such phenomena, is not a voltage regulator failure, should be to improve the input line (line thickening, try to shorten the length of the input line to reduce the voltage drop in the line).
11?, when the regulator output voltage is seriously deviated from 220V? should check ① input voltage is within the range of the regulator; ②? Whether the motor gear is seriously worn, rotation is flexible; ③? Limit switch is damaged: ④? Is the coil plane smooth; ⑤? Control board is not damaged
