The advantages and disadvantages of various communication regulated power supplies are listed below. Under normal conditions, the advantages of parameter regulator (ferromagnetic resonant regulator and regulator transformer): 1, strength: 1 firmness High (no electronic components, constructive). 2 anti-high energy disturbance (good low-pass filtering), some manufacturers plus lightning.

3 no output over pressure. 4 Input voltage scale wide (half-load input voltage lower limit can be more than 50%) 5 If the echo time is short (about 50ms) 6 Overload performance (strong ferromagnetic equipment overload capacity). 7 can make a high power supply device.

2, defects: 1 thick stupid, consumption of copper, iron data, thus the price is higher. 2 Batch production consistency (affected by iron core data and technology). 3 Source power factor is low, the power is low.

4 temperature rise, noise. 3. Some applicable situations have special prayers of reliability and anti-aging performance, such as units, banks, etc.

Second, automatic pressure regulator regulator (including disk type and column) 1, strength: 1 input voltage can be done wide (because the carbon brush moves long). 2 The output voltage waveform is the same as the input voltage waveform, the phase is also consistent. 3 high power power (self-coupling pressure loss, usual power is 95%).

4 load nature adaptability. 5 Simple manufacturing, low cost, low price. 6 can make a high-power network.

2, defect: 1 The number of jobs is short (due to carbon brush wear) 2 echo time long (due to mechanical transmission, slow motion). 3, applicable occasions: Some of the echo time, such as factory production workshop, power supply, usually electronic instruments, etc. Third, purification regulator (including fine regulator) 1, strength: 1 anti-aging performance.

2 high voltage regulation accuracy (better than ¡À 1%). 3 short echo time (40ms ~ 60ms). 4 The circuit is relatively simple, the job is secure.

2, defect: 1 with non-linear load (computer, program-controlled switch, etc.) sometimes have low frequency vibration. 2 The input side electricity loss is large, and the source power factor is low.

3 input voltage scale is not wide (usual condition is 185V ~ 255V). 3. Applicable occasion: The opposite disturbance is prayed for high units, and it is advisable to use (small-scale sharing scale), which can supply power to the computer, but it is not possible to select the voltage regulator output capacity according to the total power of the computer.

Because the computer is attributed to nonlinear loads), it is better to use 1kva ~ 5kva model, because there is a pressure of stabilization, anti-aunition, echo speed and quotation, etc. Fourth, CNC regulator 1, strength: 1 short echo time (due to double-canable silicon doing switching components). 2 can make a high power to host power supply.

3 output voltage distortion is small (no additional distortion in the machine). 4 high power. 2, defect: two-way controllable silicon components as a communication switch in the machine, simply flow through the short-circuit scene, and then affect the operation of the power supply (some manufacturers have been undergoing).

3, applicable occasions because the echo speed is fast, suitable for power supply (field operation), suitable for high-power resistance power regulators. 5. The width regulator is similar to that of the CNC, but the transformer is less tap, and the relay is used to change the tap.

1, strength: 1 circuit is simple. 2 input voltage scale width (135V ~ 280V). 3 power high (small in the machine, more than 95% of the power) 4 Offer low.

2, defect: 1 low voltage regulation (¡À 8% ~ 10%). 2 The number of jobs is short (due to the relay, the contact is simple to burn). 3.

Applicable occasion: The primary is home, power supply to the air conditioner, and launch the air conditioner when the input voltage is low. Suitable for far-away areas such as towns and towns, rural areas (large). Sixth, wide-limit regulator 1, strength: 1 fast "fast.

2 small size, light weight. 3 power is high. 4 waveform distortion is small.

5 No output overvoltage, easy to complete soft start. 2, defects: 1 circuit is more complicated, affecting the work is firm. 2 should not be made into high power.

3, applicable occasions in praying of small size, light weight, fast echo, and smaller output power. Can be powered by a fuel generator. Communication regulator processing method: present, due to various elements of power supply facilities and regional conditions, my country's communication power grid voltage is still relatively large.

Especially some distant, rural areas. High-power DC power supply Power supply grid voltage shake is two points: (1), the voltage is high and low, can not be able to stabilize within the scale of specification voltage; (2), the voltage continues to be high or low. The above two situations are greatly unfavorable in power safety and electrical appliance safety.

Using electrical appliances for a long time in such a voltage environment, the operation can cause air consumption, consuming current, high power power, severe temperature rise, and use electrical appliances cannot work properly, etc. More severe will burn the electric appliance, and even cause fire! Doubt in the power supply voltage is usually three factors;. This type is usually a small hydropower station.

2) There is a problem in the performance of power transformers in substation or distribution station, especially long-lasting age. 3) The total electricity consumption in the area is large, which causes the supply voltage to be low, and the severe and even the power supply frequency is low and then the power grid is lowered. The above-mentioned power supply network for a long period of time, the supply voltage is not stable, and it is unable to change the status quo from the floor facility from the bottom.

The best processing method is to use electricity to communicate regulators in self-supplied power grid. Three-Technology Electric Co., Ltd.

is working for a long time to communicate and produce the political power supply, supply a package for your use of electricity: 1) Users who use electrical intensity pray for non-high, we have SVC series communication regulator for You choose, this series of communication regulator output accuracy is (single phase 220V ¡À 3%, 110V ¡À 6%, three-phase 380 ¡À 4%). 2) Users who use electrical intensity pray for high-precision SBW, SJW-WB, CWY series small, medium, high-power single three-phase regulator for you to choose. This series of communication regulator output voltage accuracy is (single phase 220V ¡À 1 ~ 3%, three-phase 380 ¡À 1 ~ 3%).

Our goods have strong carry capacity, stable output voltage, and delay, overcurrent, over temperature, overvoltage maintenance. Select a Strue Series Regulator to set a safe power barrier for your electrical appliances. Because some electrical appliances contain coil assemblies, the switch regulator power supply will block the current vortex flow in the initial stage, and the occurrence of eddy current will undergo the instantaneous voltage when the electrical start is launched, causing the start of the start and the instantaneous voltage that occurs after the disconnect.

Maybe spark damage circuit. This is a regulator to maintain the normal operation of the c.
