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: 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 electricity in the DPS.UPS, etc. are temporary power to Caesar ah: DPS is the power of the equipment being tested, UPS is uninterrupted power supply,

Q: Is the industrial atomizer good with a switching power supply or a toroidal transformer?: In the case of large fluctuations in the power supply or industrial equipment is 24 hours long-term need to supply the case, the use of transformer power supply more reliable, because it is very skin and difficult to damage. The switching power supply is cheap, the use of low cost, power efficiency relative to the transformer power supply high.

Q: Do you need a separate dedicated power supply for each color dome camera?: There are two ways to power the camera 1. Separate power supply 2. Power supply (power supply needs to match the power of the load)

Q: With tl494 and do with UC3842 Which power is better?: In the stability and efficiency is no way to distinguish, to see you do the specific parameters of power, 100W, including the proposed use of UC3842 flyback, 100W-500W recommended UC3842 forward, 500W-1000W recommended TL494 half bridge, 1000W-2000W It is recommended to use TL494 full bridge.

Q: PIC microcontroller used in the industrial field, the power supply using switching power supply plus B0505 isolation module, anti-jamming performance is better: You use the PIC with which models, switching power supply to the chip power supply is no problem, the key is to single-chip power supply filter to do a good job. Relay output to use optocoupler isolation and so on. B0505 output test must have a small load and input and output must be added filter capacitor, otherwise interference is great.

Q: The 2-way power supply is connected to a 16A 8-bit PDU in the cabinet using a 16A industrial connector: 1 Road 16A into, just connected to the 16APDU Lane, just right. Second Road, then it is estimated that a then electricity, a UPS. Smart is not intelligent and it does not matter. A little better room will be equipped with this.

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: 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: 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.
