Product Description:

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:EPS emergency power supply and DC screen is one thing, what is the difference between the two?
DC screen [1] is a short description of the DC power supply operating system. Universal name for the intelligent maintenance-free DC power supply screen, referred to as DC screen, universal model for the GZDW. Simply put, the DC screen is to provide a stable DC power supply equipment. (Directly converted to DC220V or DC110V when inputting 380V power supply, and input directly to battery power when input (mains and standby) are input - DC 220V or DC110V: it can be said to be an industry Dedicated emergency power supply). Power plants and substations in the power of power supply are now used in DC power supply, which for the control load and power load and DC accident lighting load to provide power, is the basis of contemporary power system control and protection. The DC screen is composed of crossover power unit, charging module unit, step-down silicon chain unit, DC feed unit, power distribution monitoring unit, monitoring module unit and insulation monitoring unit. It is mainly used in small power plants, hydropower stations, substations, and other users of DC equipment (such as petrochemical, mining, railway, etc.) for power substation and sub-circuit. Electrical protection and fault lighting and other occasions.
Q:Industrial UPS power supply how to choose?
Ren of UPS power supply, has been successfully applied to more than 300 factory-level customers, is committed to the factory-class customers with a full range of power and energy solutions, any of the UPS power supply, stable performance, first-class quality, each UPS power factory To go through at least 40 tests to ensure that the product is absolutely stable to reach the hands of customers, any of the UPS power supply, factory UPS power solutions for the best partners.
Q:Industrial 24V switching power supply outlet "-" Is it necessary to connect with the earth?
Switching power supply is the use of modern power electronics technology to control the switch on and off the time ratio, to maintain a stable output voltage of a power supply, switching power supply is generally composed of pulse width modulation control IC and MOSFET. With the power electronics technology development and innovation, making switching power supply technology is constantly innovating.
Q:Military grade power supply, industrial power supply, civil power supply where the difference?
These requirements are graded, the level of the points is based on the quality of the power supply, and the use of classificatio
Q:Is the industrial atomizer good with a switching power supply or a toroidal transformer?
Need to be determined according to the use of the situation. Switching power supply and transformer power supply has its own advantages and strengths.
Q:What is the best industrial power industry?
If there is more need, you can contact the manufacturer directly, require special customization.
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: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.
Q:Industrial power cabinet generally use what brand of power
3.APC, the old brand, was EMERSON acquisition, but the market share and then gradually reduced.
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.
