Product Description:

 

Technical Features:

SVC (Static Var Compensator) is composed of by thyristor controlled reactor (TCR) and passive filter (FC). It is a compensator with parallel connection in the grid, and it quickly and automatically adjust the system reactive power according to the load working condition.

 

Application Scope:

Reactive compensation and harmonic filtering of electric power, petroleum, chemical industry, metallurgy, wind power, photovoltaic power generation, hoist, electric arc furnace, electric locomotive, steel rolling production line, high voltage power lines, etc.

 

Product Principle


Combining with the control concept of current international mainstream, the heating power supply adopts the digital design to make the machine run more efficiently.

The heating power supply adopts the N + 1 redundancy technology to ensure the entire sapphire production cycle. We adopt DSP digital control mode, making the output voltage accuracy to five over ten thousand, and it has analog peripheral interface, 485 communication interface, etc. Using IGBT as power device to improve working efficiency and conform to the current trend of saving energy and reducing consumption.


Technical Features

1. Control system: We adopt American TI company DSP processor, which is of high control accuracy and high reliability. It employs PI control technology with advanced hardware and software. If there occurs fluctuation in power grid voltage, it can automatically maintain the current output power constantly.

2. HMI: It displays parameters in real time such as output voltage, current and power, etc.. It works with function of data maintained when power fails and it is easy to inquire and maintain the record of failure time and fault type.

3. High efficiency and low pollution: We adopt the phase shifting full bridge soft switching (ZVS) control technology, to realize the IGBT open and shut off under zero voltage. It greatly reduce the IGBT switching loss, the noise pollution and electromagnetic interference of the power. The output voltage waveform is completely smooth, and it runs more safe and stable.

4. High reliability: We adopt the multi-unit structure of N + 1, and the multiple units work together in normal condition. Failure of one unit does not affect the present output power and it is more convenient to maintain normal operation of equipment.

5. Perfect protection: Overtemperature protection and output over-voltage or over-current protection, output short circuit and grounding protection, the limit protection of water flow and strike fire protection, etc.

6. Flexible interface: Input and output support simulation approaches such as switch, voltage and current signal, Modbus, MB + and Profibus etc. data communications control.

Q:What brand of power control module is better? You know MINMAX and C & D two brands.
Look at your main application. If cheap cheap goods, everywhere, a search on the Internet, a lot. But the quality of good and bad, you have to grasp yourself.
Q:With tl494 and do with UC3842 Which power is better?
3842 is a single output, the general switching power supply are used, TL494 is a dual output, can be made into complementary output, can also be made into a single output is mainly used in computer power .3842 simple, 494 complex point of stability and efficiency! Mainly on the power of the design
Q:The 2-way power supply is connected to a 16A 8-bit PDU in the cabinet using a 16A industrial connector
1 Road 16A into, just connected to the 16APDU Lane, just right. Second Road, then it is estimated that a then electricity, a UPS. Smart is not intelligent and it does not matter. A little better room will be equipped with this.
Q:Switching power supply S-120-12 monitor dedicated 12V / 10A camera power supply how to meet the amount of power
Second, the switching power supply S-120-12 Switching Power Supply S-120-12 is Shanghai Mingwei production of switching power supply, type: DC switching power supply , Model: S-120-24,   Input voltage: 100-264 (V), output power: 120 (W), output voltage: DC12V (V).
Q:Site with industrial power 380V / 50hz, electrical equipment is 110v / 60hz. Is there a solution?
The simplest solution, no 380v, 220v direct lighting, then 220v turn 110v transformer, output 110v, 50hz, then the equipment. Not a big problem
Q:Multimeter measuring industrial furnace box and power supply resistance is 6-15mΩ, which is leakage it?
All metal shell equipment require reliable grounding, whether or not you can continue to use,
Q:What is the industrial electricity voltage and frequency of Peru, Ecuador and Colombia?
Colombia's industrial voltage and frequency are: [single phase] 110V / 220V, [three phase] 220V, [frequency] 60HZ;
Q:Industrial control system power supply Why is the choice of DC24V power supply? Why not 17V? 11V?
which take into account a number of factors, the first is a safe voltage, the body does not produce electric shock Dangerous, the second can be regarded as a relatively high safety voltage, can reduce the current in the same power, and then 24 is a multiples of the majority, set the standard, of course, to consider and a variety of batteries are also concerned,
Q:PIC microcontroller used in the industrial field, the power supply using switching power supply plus B0505 isolation module, anti-jamming performance is better
You use the PIC with which models, switching power supply to the chip power supply is no problem, the key is to single-chip power supply filter to do a good job. Relay output to use optocoupler isolation and so on. B0505 output test must have a small load and input and output must be added filter capacitor, otherwise interference is great.
Q:Industrial power cabinet generally use what brand of power
At present, industrial UPS, the market usually use several brands. 1.EMERSON, EMERSON not only provide UPS products, but also provide supporting engineering solutions and engineering support.
