Application Scope:

It is applied in heating of sapphire furnance, silicon carbide furnace and metal smelting etc. in photovoltaic industry.

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 is the allowable fluctuation range of the industrial standard power supply 380v power supply voltage?: With other levels of power supply voltage fluctuations are as follows: 35kV and above supply voltage positive and negative deviation of the absolute value does not exceed the nominal system voltage l0%. Note: If the upper and lower deviation of the electrical voltage (both positive or negative), according to the larger deviation of the absolute value as a basis for measurement.

Q: My magnetron is used in the industry, my dedicated power to start less than 2 minutes to stop,: This reason is much better, next to the investigation 1 heat problem magnetron with or without cooling fan, generally if there is no cooling or cooling broken, then the magnetron will work for 2 minutes to burn, you measure the same as the filament is passed. Burn is a magnet cracking

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: Industrial plant design 10 kV substation from the power supply to the client side, such as mechanical equipment, such as the overall structure of the connection diagram: statistics good variety of required parameters; and then to the power distribution according to user needs to choose step-down transformer, draw high and low voltage system diagram, Details of the work and then slowly do ...

Q: Industrial switching power supply which brand is good, including imported.: Taiwan Mingwei Many domestic countries are imitation of it. Foreign switching power supply to do less, more than 75% of the world in the mainland.

Q: What is the best industrial power industry?: haoyang Power The key is to see what you use in the occasion, you need the power of the accuracy requirements of how high

Q: Computer power can be inserted in the air conditioning dedicated socket: The air conditioning socket can provide a greater current than the ordinary socket (not forcibly filling the electrical current).

Q: What brand of power control module is better? You know MINMAX and C & D two brands.: See you want to DC or exchange. DC power personal feel that Siemens is very good.

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: UPS uninterruptible power supplies, electronic power products, industrial computers and embedded computers.: This is really hard to say, do sales, compared to the technical content of the product, more need is the sales skills. When you decide to engage in the sales industry, selling a product, sales can reflect your value, rather than the product itself, the technical content.
