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 industrial electricity voltage and frequency of Peru, Ecuador and Colombia?
- Ecuador's industrial voltage and frequency are: [single phase] 120V / 127V, [three phase] 208V / 220V, [frequency] 60HZ;
- Q:PIC microcontroller used in the industrial field, the power supply using switching power supply plus B0505 isolation module, anti-jamming performance is better
- There is no direct relationship between isolation and anti-interference. If you can not remove the interference source, cut off the interference source transmission path is an effective method. Power supply interference can be considered using the power filter.
- 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:EPS emergency power supply and DC screen is one thing, what is the difference between the two?
- Mainly used in road traffic lighting, venue lighting, building fire escape lighting, fire pumps, spray pumps and other fire equipment to provide emergency power supply, EPS fire emergency power supply through the CCC China national compulsory product certification, the current state through the 3C certified EPS Fire emergency power supply size is 0.5KVA to 110KVA. EPS fire emergency power supply can be divided into emergency lighting, hybrid and power inverter EPS emergency power supply three categories.
- Q:Led special power how to wiring
- After the power is connected, if the light is not bright, then the GND and 12V on the line down, if the swap is still not bright, or light burned, or the power is broken, or the line open.
- 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:What is the frequency of electricity in Bangladesh?
- The People's Republic of Bangladesh (Bengali: G?n?pr?jat?ntri Bangladesh), referred to as Bangladesh and South Asian countries, is located in the north of the Bay of Bengal, a small part of the southeastern mountainous area and Myanmar neighbors, east, west and north are connected with India, and in the northern border A large number of enclaves, the total area of 147570 square kilometers.
- 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
- You design this content contains the transmission and variable distribution of two large, from your question you can see you like no clue, do not know where to start, step by step,
- Q:Do you need a separate dedicated power supply for each color dome camera?
- General color hemisphere no infrared lamp power consumption is small, a 1A power supply if it is safe, then with 2 is no problem
- Q:Driving recorder dedicated power box for what use
