Product Description:


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:Industrial 380 inverter how to enter the home 220 power supply work
Surely need to install the press
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: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:S-350-12 monitoring dedicated switching power supply 12V29A transformer connection
12V switching power supply connected to the positive and negative, then the power will not burn, and most of the output is not, if it is a new power supply, then you can change one. The next time to pick up the first time with a multimeter to measure whether there is a short circuit, the best one of a power, on a power out of an image, no image and then check.
Q:Do you want to use the DC24V of the alarm system for the power cord of the bus-specific fire-fighting telephone?
2, when the current use of fire telephone module access, the module itself needs to provide DC24V power supply, power supply by the fire alarm controller output power bus. The fire telephone module, respectively, access to the power bus, telephone bus (fire phone controller output), and output two bus access to the phone jack and telephone extension.
Q:PIC microcontroller used in the industrial field, the power supply using switching power supply plus B0505 isolation module, anti-jamming performance is better
Certainly better, or else else to develop this power module why? All with a direct switch power supply! The
Q:The 2-way power supply is connected to a 16A 8-bit PDU in the cabinet using a 16A industrial connector
The total load of the equipment for each enclosure matches the total load carried by the PDU. The total load of the PDU must be greater than the total load of the device.
Q:With tl494 and do with UC3842 Which power is better?
3842 is a single output, the general switching power supply are used, TL494 is a dual output, can be made into complementary output, can also be made into a single output is mainly used in computer power .3842 simple, 494 complex point of stability and efficiency! Mainly on the power of the design
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)
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.
