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: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: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:Industrial power cabinet generally use what brand of power
2.PowerWARE, EATON subordinate brands, including SANTAK is EATON's brand, also accept direct engineering orders, that is to provide products while also providing engineering services and engineering warranty service.
Q:What is the allowable fluctuation range of the industrial standard power supply 380v power supply voltage?
With other levels of power supply voltage fluctuations are as follows: 35kV and above supply voltage positive and negative deviation of the absolute value does not exceed the nominal system voltage l0%. Note: If the upper and lower deviation of the electrical voltage (both positive or negative), according to the larger deviation of the absolute value as a basis for measurement.
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).
Q:Led special power how to wiring
L line, N line access 220V mains (then the home socket) N line behind the ground wire can not use the indoor;
Q:Multimeter measuring industrial furnace box and power supply resistance is 6-15mΩ, which is leakage it?
All metal shell equipment require reliable grounding, whether or not you can continue to use,
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:The 2-way power supply is connected to a 16A 8-bit PDU in the cabinet using a 16A industrial connector
This is a dual power input to ensure that the device will not be powered down
Q:My magnetron is used in the industry, my dedicated power to start less than 2 minutes to stop,
2 power supply general power supply has a self-protection function is not the same as the heat can not work
