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:A led lamp with a dedicated power to bring a few lights
Third, the virtual standard power drill LED lights with different power of the loopholes: Customers in the purchase of the use of light, according to the previous habit when the 14.4W / m: If you want to bring light with 30 meters, the power will be 30 meters light with 14.4W = 432W, customers will use 450W power supply, but As the market is a lot of 7.92W / m light belt, 30 meters is 30 * 7.92 = 237.6W, the production of virtual power supply manufacturers to seize this point, the 240W power supply virtual standard 450W. So the actual user is to use 450W power supply price to buy Buy the actual power supply is 240W. For example: 450W virtual power supply is 80 to 85 yuan / Taiwan, RC full power 240W is 73 yuan / Taiwan, in fact RC power supply high reliability, higher load, the price is more affordable.
Q:Power for ups power supply which well-known imported brands
APC UPS is Nixon visit to China to bring the national ceremony, huh, huh EMERSON, SANTAK
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: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: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:Industrial electricity (380V) what the color of the wire, which is the line of fire, which is the zero line
Zero line of fire: zero line Fire line refers specifically to the power supply lines, electricity supply voltage of 220 volts (V). It includes a zero line [N] and a fire line [L], zero line ground (ground is zero) so called the zero line. FireWire, is the circuit power transmission line. Zero line, mainly used in the working loop, from the transformer neutral point after grounding lead the main line.
Q:Industrial control system power supply Why is the choice of DC24V power supply? Why not 17V? 11V?
This is a series of standards in the power of the standard, which is a long time after the practice summed up and set the standard,
Q:Industrial power cabinet generally use what brand of power
At present, industrial UPS, the market usually use several brands. 1.EMERSON, EMERSON not only provide UPS products, but also provide supporting engineering solutions and engineering support.
Q:Industrial switching power supply which brand is good, including imported.
Japan LAMBDA Taiwan Ming Wei switching power supply (MW) MEANMALL Shanghai Heng Fu switching power supply (HF) Shanghai Lan Fu switching power supply (LanFu) Chaoyang Power Jinwei source power supply Nuclear in the pass Japan Kosovo Siemens
Q:Apple 4s dedicated mobile power are what?
Charging Po has 5V / 2A charge output, 5V / 1A charge output. 2, Apple 4S use 5V / A charge output. 3, selected by the polymer lithium battery as a storage unit.
