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: What is the frequency of industrial electricity in the Philippines?: Frequency, is the unit time to complete the number of cyclical changes, is to describe the amount of periodic movement frequency, commonly used symbols f or u said, in units of seconds. In order to commemorate the German physicist Hertz's contribution, people put the frequency of the unit named Hertz, referred to as "He". Each object has an amplitude independent of its own nature, called the natural frequency. The concept of frequency is not only used in mechanics, acoustics, but also in electromagnetics and radio technology.

Q: Industrial instrument power supply with a good switching power supply or transformer: Upstairs brother who understand the wrong, 1: switching power supply unless it is more expensive resonant switching power supply, or its interference than the general composition of the transformer circuit should be large, you look at the high-end audio Why not switch power ( There are special, open-loop resonant) 2: switching power supply so-called "anti-lightning) is only one or two varistors connected in parallel at the input, anti-lightning that is what way to see the lightning, the function is limited, this and the transformer The difference is not large, the transformer and the post-pole regulator circuit .3 transformer output voltage for the exchange, want to get a stable DC voltage output must be added to the circuit, so the regulator is more stable depends on your components and circuits, not switching power supply It must be better than the transformer. I would like to say that the transformer is better than the switching power supply, but each has its own advantages and disadvantages, for the general instrument, I still recommend the use of genuine switching power supply, if it is very sensitive instrument, it is optional transformer circuit, or you will find There is interference.

Q: Is the industrial atomizer good with a switching power supply or a toroidal transformer?: Need to be determined according to the use of the situation. Switching power supply and transformer power supply has its own advantages and strengths.

Q: Do you want to use the DC24V of the alarm system for the power cord of the bus-specific fire-fighting telephone?: I have not seen the telephone extension to use 24V power supply, are generally by the fire center bus phone host pull two pairs of lines to the bus phone module (two pairs of lines are the telephone audio line and telephone bus), and then from the phone module Pull a pair of lines to the telephone extension (this line for the telephone audio line).

Q: The 2-way power supply is connected to a 16A 8-bit PDU in the cabinet using a 16A industrial connector: 1 Road 16A into, just connected to the 16APDU Lane, just right. Second Road, then it is estimated that a then electricity, a UPS. Smart is not intelligent and it does not matter. A little better room will be equipped with this.

Q: Industrial 24V switching power supply outlet "-" Is it necessary to connect with the earth?: Switching power supply is the use of modern power electronics technology to control the switch on and off the time ratio, to maintain a stable output voltage of a power supply, switching power supply is generally composed of pulse width modulation control IC and MOSFET. With the power electronics technology development and innovation, making switching power supply technology is constantly innovating.

Q: US Industrial Electricity Voltage: US industrial electricity as follows: US Voltage Standard (ANSI C84-la-1980): 1. The power supply system design should be carried out according to "range A". The voltage deviation range of "range B" should be rare, and it should take measures to achieve the requirement of "range A".

Q: Switching power supply S-120-12 monitor dedicated 12V / 10A camera power supply how to meet the: Which L, N, ground for the switching power supply S-120-12 power input, respectively, then the AC voltage phase line (commonly known as FireWire), the center line, ground terminal. COM, COM, + V, + V is the output of the switching power supply S-120-12, where each COM and + V are connected to the negative and positive terminals of the 12V / 10A camera respectively.

Q: What is the frequency of electricity in Bangladesh?: The People's Republic of Bangladesh (Bengali: G?n?pr?jat?ntri Bangladesh), referred to as Bangladesh and South Asian countries, is located in the north of the Bay of Bengal, a small part of the southeastern mountainous area and Myanmar neighbors, east, west and north are connected with India, and in the northern border A large number of enclaves, the total area of 147570 square kilometers.

Q: UPS uninterruptible power supplies, electronic power products, industrial computers and embedded computers.: This is really hard to say, do sales, compared to the technical content of the product, more need is the sales skills. When you decide to engage in the sales industry, selling a product, sales can reflect your value, rather than the product itself, the technical content.
