Application Scope

The power supply is comply with current trend of energy conservation and emissions reduction, and be specially developed for the new efficient heating power supply of single crystal furnace. It is a new generation product of thyristor rectifier power supply, with the merits of small volume, light weight and high efficiency. Compared with other thyristor rectifier power supply, it can obviously realize energy-saving 10% ~ 20%.

Product Principle

The new generation of DC switching power supply is constituted of HF transformer with high efficiency and power devices (like original imported IGBT and ultrafast recovery diodes, etc.). It adopts the phase shifting full bridge soft switching (ZVS) control technology, to improve the power conversion efficiency and increase the stability of the output voltage and current.

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: S-350-12 monitoring dedicated switching power supply 12V29A transformer connection: may 1, you are on the wiring when the burning, it is the power is not big enough, is overloaded work. 2, you do not connect, may be connected together positive and negative, resulting in short circuit burned. Recommendation: change the new power supply, it is necessary to connect all the lines, and then the first group, to see the heat situation, to determine whether the next group.

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: 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: Multimeter measuring industrial furnace box and power supply resistance is 6-15mΩ, which is leakage it?: your equipment team safety requirements are not standardized, if you can answer, that is irresponsible to you.

Q: Switching power supply S-120-12 monitor dedicated 12V / 10A camera power supply how to meet the: First, the switching power supply S-120-12 and monitor the dedicated 12V / 10A camera power wiring Switching power supply S-120-12 has seven terminals: L, N, ground, COM, COM, + V, + V.

Q: Computer power can be inserted in the air conditioning dedicated socket: The computer power supply can be plugged into a dedicated outlet for air conditioning. The voltage used in the air conditioning socket is still civilian 220V AC, the same as the computer power input voltage level.

Q: What is the industrial electricity voltage and frequency of Peru, Ecuador and Colombia?: Peru's industrial voltage and frequency are: [single phase] 110V / 220V, [three phase] 220V, [frequency] 60HZ;

Q: Industrial power cabinet generally use what brand of power: 3.APC, the old brand, was EMERSON acquisition, but the market share and then gradually reduced.

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: UPS uninterruptible power supplies, electronic power products, industrial computers and embedded computers.: This product, then, are mature products, that is, high-tech missile aircraft submarine technology, the world is not a lot of countries in the military competition? The The Some people sell lighters to sell towels a year can sell hundreds of W, in the final analysis, or sales of technical problems.
