Application Scope

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.

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, and the on line function can reduce the impact on power grid.

Technical Features

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: A led lamp with a dedicated power to bring a few lights: Second, the current market for some easy to burn the lamp beads 1, some manufacturers themselves are cottage factory, no engineering and technical personnel. Just buy other manufacturers to bring back the copy of the lights, and other manufacturers on the lamp with the current limiting resistor is how much, according to how much of the current limiting resistor. Do not know LED chips each batch of current are not the same, each batch should be based on the actual LED chip current limiting current limiting resistor. So that current limiting current limit is not enough, it led to some light belt easy to burn out of the situation. 2, the use of light with the customer is not clear the actual power of each light band, chaos with power, and the lights are often in a bright state, power supply is insufficient, eventually leading to light burned. 3, another reason: some power manufacturers to deceive consumers: the use of copper clad aluminum transformer, because the cooling effect of aluminum than copper transformer is poor, in the power, the power may be a time to achieve, but the power of a long time, power It can not afford the power of the lamp, it will burn the lamp, or burn the power.

Q: EPS emergency power supply and DC screen is one thing, what is the difference between the two?: EPS fire emergency power supply is a centralized fire emergency power supply, in the city power failure and abnormalities, to continue to supply power to the load to ensure that no power to protect people's lives and property security.

Q: Industrial electricity in the DPS.UPS, etc. are temporary power to Caesar ah: and some can delay a few minutes, some can be delayed for several hours, but if the request for a few days that can not be achieved, Only when the temporary 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?: General color hemisphere no infrared lamp power consumption is small, a 1A power supply if it is safe, then with 2 is no problem

Q: PIC microcontroller used in the industrial field, the power supply using switching power supply plus B0505 isolation module, anti-jamming performance is better: There is no direct relationship between isolation and anti-interference. If you can not remove the interference source, cut off the interference source transmission path is an effective method. Power supply interference can be considered using the power filter.

Q: Why do you need to use isolated power in industrial communications?: if not isolated, and other devices together, it will cause other equipment to interfere with the communication equipment.

Q: US Industrial Electricity Voltage: 2. Requirements for "Scope A": 115 ~ 120V System: When lighting: 110 ~ 125V of electrical equipment; power supply point 114 ~ 126V. No lighting: electrical equipment at 108 ~ 125V; power supply point 114 ~ 126V. 460 ~ 480V system: (including 480 / 277V three-phase four-wire system) When lighting: power equipment at 440 ~ 500V; power supply points 456 ~ 504V. No lighting: electricity equipment at 432 ~ 500V; power supply points 456 ~ 504V. 13200V system: power supply point 12870 ~ 13860V.

Q: Industrial electricity (380V) what the color of the wire, which is the line of fire, which is the zero line: 30KW current about 60A or so, calculated by P = ui to calculate, mainly to consider the line voltage and phase voltage conversion, 380V should be replaced by phase voltage. ? 60A of the meter generally do not have to consider the installation of a more current transformer, 75 / 5A on the line, so that the secondary current in the 4 amps, the meter with 5A on the line, calculate the power when remember to multiply 15 times.

Q: Computer power can be inserted in the air conditioning dedicated socket: The air conditioning socket can provide a greater current than the ordinary socket (not forcibly filling the electrical current).
