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:Power for ups power supply which well-known imported brands
Emerson (Emerson), Merlin Gerin (MGE) This is the best power of the two brands. China Telecom, mobile, China Unicom, PetroChina and other cattle are the use of these two brands of cattle. APC, Hills is the best two brands of low power. Telecommunications, mobile, Unicom and other business units may be more use. Emerson has a dedicated UPS for power and other industries. Need to contact me.
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:Meizu special mobile power is which brand?
Meizu official did not move the power supply products, but before iWALK brand is designed for Meizu out of a 2500 mAh white mobile power, you can go to Jingdong Mall search.
Q:UPS uninterruptible power supplies, electronic power products, industrial computers and embedded computers.
If you really want to reduce the competition, then I think you only have to negotiate with the rotten, the oil, Sinopec bought, and then you start selling oil, so in China you really can not find a competitor.
Q:Why do you need to use isolated power in industrial communications?
In simple terms, the need for isolation mainly involves: communication equipment on the power of the stability and anti-interference requirements are high,
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:Dell 9020MT business computer can only use 290W dedicated power?
That is, the power of a machine usually said, the rated power of the machine is certain, P = Fv, so the machine produces the force and the running speed is inversely proportional. For example, when the car is running on a flat asphalt pavement, the required traction force F is small and the speed can be larger; if the traction is large when the road is not flat or up the mountain, it is necessary to switch to low speed.
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:Fire emergency lights and evacuation signs need to receive a dedicated fire power on it?
The effect of the fire emergency light is to provide emergency evacuation lighting after the circuit is powered off, which is characterized by being controlled when the power supply is normal and providing temporary emergency lighting from the internal battery when the power supply fails (power failure).
Q:My magnetron is used in the industry, my dedicated power to start less than 2 minutes to stop,
2 power supply general power supply has a self-protection function is not the same as the heat can not work
