Polysilicon ingot furnace heating power supply plays an important role in polysilicon ingot furnace heating system to provide electricity for crystal ingot casting process and it ensures that the furnace can work under the rated temperature. The power supply can control ingot furnace heater temperature of the upper and lower layer respectively, and it is with merits of high control precision, flexible control and smaller current shock to the power grid.
Combining with the control concept of current international mainstream, the heating power supply adopts the digital design to make the machine run more efficiently, and the on line function can reduce the impact on power grid.
1. Flexible operation and convenient maintenance: It installs LCD (Liquid Crystal Display) monitor panel and displays operation parameters in real time. The control parameters can be modified online and fault information can be automatically recorded, etc.
2. High control accuracy and good stablity: It adopts phase-locked loop synchronous circuit and digital trigger. On sampling algorithm of the load characteristics, it has multiple software protection function. The power devices and circuit breaker etc. adopt international and domestic famous brands.
3. Advanced processing technology of transformer: Transformer adopts high-low pressure complete foil coil winding, step laminated and damping measures. It is with merits of low noise and loss, light weight with small volume, and saving installation space. It has strong heat dissipation ability to achieve 20% overload running stably under the condition of forced air cooling.
4. Double roads of output power: Two lines of output power can work in following mode or in alternate mode, which makes it easy for users to better control the output power.
5. Higher power factor and less current distortion.

- Q:What is the frequency of industrial electricity in the Philippines?
- China's electricity voltage and frequency:
Voltage: Resident 220V, Industrial 380V. Distribution: 10 000V, up there 35kV, 110kV, 220kV, 330kV, 500kV, 750kV, 1000kV. Frequency: 50 HZ.
- Q:Industrial UPS power supply how to choose?
- Ren of UPS power supply, has been successfully applied to more than 300 factory-level customers, is committed to the factory-class customers with a full range of power and energy solutions, any of the UPS power supply, stable performance, first-class quality, each UPS power factory To go through at least 40 tests to ensure that the product is absolutely stable to reach the hands of customers, any of the UPS power supply, factory UPS power solutions for the best partners.
- 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?
- 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.
- Japan LAMBDA
Taiwan Ming Wei switching power supply (MW) MEANMALL
Shanghai Heng Fu switching power supply (HF)
Shanghai Lan Fu switching power supply (LanFu)
Jinwei source power supply
Nuclear in the pass
- Q:With tl494 and do with UC3842 Which power is better?
- UC3842 I now do this with switching power supply
- Q:Apple 4s dedicated mobile power are what?
- 4, select the point of attention:
1) look at batteries,
2) to see the conversion rate,
3) look at materials,
4) to see the mobile power brand,
- Q:Do you want to use the DC24V of the alarm system for the power cord of the bus-specific fire-fighting telephone?
- 1, the bus system of the fire telephone extension or telephone jack is no need for external power supply, through the fire telephone bus directly access the fire telephone controller. But the fire telephone controller (usually with the alarm controller set disk) requires DC24V power supply, and by the fire alarm controller to provide;
- Q:What is the application of IF power supply in the industrial field?
- 2, in the application of heat: the workpiece in the heating process, the overall heating of the metal, the workpiece can reach a temperature range inside and outside. Also used in the casting of metal materials, stamping, extrusion, rolling and other heating before processing.
As the IF furnace heating time is short, almost no heating or only a small amount of oxide, so the weight loss caused by the scale of less than 0.5%, while the gas furnace oxide damage caused by weight loss of up to 20%, coupled with the loss of pickling, waste is very big. So the use of IF power, can greatly improve efficiency, and easy maintenance, reduce labor intensity, easy to achieve automation.
Induction heating, due to the high frequency of the skin effect, the density of the induced current is gradually reduced from the surface to the inside. The same material, the higher the frequency, the current density from the outside to the inside to reduce the faster.
- 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)
