Product Description:


Application Scope

The HF DC power supply is of high efficiency and reliability, which is specially developed for the Kyropoulos sapphire furnace and it, is with merits of high power factor, low harmonic current and high efficiency.

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:A led lamp with a dedicated power to bring a few lights
Four, warm tips: 1, compared to the merits of power supply can not only compare the number of W marked by the power supply, depending on the actual load power supply; electronic material selection; transformer whether the aluminum transformer. 2, the proposed customer knowledge of the lamp with a certain understanding, you can configure their own test tools to detect the actual power of each batch of lights, matching more economical, real power. Professional power supply manufacturers Links: LED switching power supply Shenzhen switching power supply switching power supply rain power
Q:UPS uninterruptible power supplies, electronic power products, industrial computers and embedded computers.
This product, then, are mature products, that is, high-tech missile aircraft submarine technology, the world is not a lot of countries in the military competition? The The Some people sell lighters to sell towels a year can sell hundreds of W, in the final analysis, or sales of technical problems.
Q:Computer power can be inserted in the air conditioning dedicated socket
It should be noted that the air conditioning sockets are 16A / 250V specifications, jack distance greater than the ordinary 10A / 250V socket, so the computer power plug must be replaced by 16A socket can be inserted into the air conditioning socket. Therefore, the computer power plug in the use of air conditioning socket is possible.
Q:Why do you need to use isolated power in industrial communications?
In addition, between high and low voltage in order to avoid high-voltage equipment on the low-voltage equipment interference, or high and low pressure need to be separated, will be used to isolate.
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:Dell 9020MT business computer can only use 290W dedicated power?
In the normal operation of the working conditions, the power of the power output or power consumption of equipment input power. Often "kilowatts" as a unit. Also refers to the factory production of the machine in the normal work can reach the power.
Q:What is the difference between computer power and industrial switching power supply?
From the power of the property terms, there is no difference. But from the functional point of view. Computer power can belong to industrial power. A wider range of industrial power supplies, the use of more power for industrial power. Generally believed that the power supply for industrial equipment, can be called industrial power. Also refers to those who are more powerful, more power supply.
Q:Industrial UPS power supply how to choose?
UPS power supply battery size determines the length of the load power supply, the specific load is also based on the need to set, such as: If the injection machine in the electricity after the break need 1 hour power supply to ensure its normal stop, then our battery Size needs to be based on the size of the injection molding machine to match the appropriate battery, any of the Group's UPS power supply can match the UPS battery, you can also have their own customers to buy.
Q:Apple 4s dedicated mobile power are what?
5) to see product charge management, 6) see compatibility, 7) to see the characteristics of the product features, 8) to determine the positioning of the purchase of products, 9) Note the weight of the product.
