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:Emergency lighting should not take fire special power supply, right?
3 .... in talking about emergency tools. All the emergency Deng has a fast battery and a module like the power of the things. (This thing with the fire touch a quick working principle, the module which has a normally open and normally closed point, when the electricity from the time he was Long open, the charging state, the mains of a short-circuit contacts normally closed, the battery will be through the module command to start the emergency lights.    The building is the building of the 7th floor, 8th floor fire, the fire host to receive the fire signal, the host to the layer of fire strong cut a command: strong cut non-fire (this refers to the city's electricity is the lighting point ). When this layer is in a power failure state: The emergency principle according to Article 3. Emergency lights are not used fire power
Q:What is the difference between computer power and industrial switching power supply?
No difference, but the power is not the same, use is not the same
Q:What brand of power control module is better? You know MINMAX and C & D two brands.
See you want to DC or exchange. DC power personal feel that Siemens is very good.
Q:Military grade power supply, industrial power supply, civil power supply where the difference?
Industrial power supply, there is no military power there is strict. Civil power, that is, we generally use the power, not very strict requirements, but there must be in the request,
Q:Fire emergency lights and evacuation signs need to receive a dedicated fire power on it?
Fire emergency lights do not need can not receive a dedicated fire power, the signs can be received on the special fire power, if it is with the battery signs do not need to be connected to the special fire power.
Q:Industrial switching power supply which brand is good, including imported.
Mingwei, Heng Fu, Mao Shuo, Huawei, Kang Su, Nova, a joint, and so on, too bad to say
Q:A led lamp with a dedicated power to bring a few lights
Know the exact power of LED lights on the best, your power is 24 * 4.2 = 100.8W, the 100.8W in addition to the light of the power per meter can, if I do not know, look at the following: One, the same circuit with LED lights, but the power and LED quality is different Why? 1, LED lights with the first launch, because the price space is relatively large, light manufacturers are using high current consistency, high brightness LED chip, this type of chip current is: 0.02A; Later, due to the price of light bulb market competition, many lights with manufacturers to use the brightness is not high, the current is not consistent with the LED chip, this type of LED chip current is: 0.011A. 2, then we use the most commonly used 5050 lamp beads, for example, first calculate the power of a lamp beads: If it is good quality LED chip: a single chip current of 0.02A, then a lamp current of 0.02A × 3 = 0.06A. If it is poor quality LED chip: a single chip current of 0.011A, then a lamp beads current 0.011A × 3 = 0.033A. 3, now we come to calculate the power of three for a group Good quality chip: 12V × 0.06A = 0.72W, 1 meter lamp with 60 lamp beads composed of 20 groups, 1 meter power 0.72W * 20 = 14.4W Poor quality of the chip: 12V × 0.033A = 0.396W, 1 meter lamp with 60 lamp beads composed of 20 groups, 1 meter power 0.396W * 20 = 7.92W
Q:Industrial instrument power supply with a good switching power supply or transformer
Upstairs brother who understand the wrong, 1: switching power supply unless it is more expensive resonant switching power supply, or its interference than the general composition of the transformer circuit should be large, you look at the high-end audio Why not switch power ( There are special, open-loop resonant) 2: switching power supply so-called "anti-lightning) is only one or two varistors connected in parallel at the input, anti-lightning that is what way to see the lightning, the function is limited, this and the transformer The difference is not large, the transformer and the post-pole regulator circuit .3 transformer output voltage for the exchange, want to get a stable DC voltage output must be added to the circuit, so the regulator is more stable depends on your components and circuits, not switching power supply It must be better than the transformer. I would like to say that the transformer is better than the switching power supply, but each has its own advantages and disadvantages, for the general instrument, I still recommend the use of genuine switching power supply, if it is very sensitive instrument, it is optional transformer circuit, or you will find There is interference.
Q:Driving recorder dedicated power box for what use
3) to stop the process has been video, the need to split from the car line out of the conversion, the installation of a called "power through" adapter, the battery voltage can be automatically stopped when the recorder power supply (to prevent the battery voltage is too low Do not burn fire)
