Product Description:

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?
China's electricity voltage and frequency: Voltage: Resident 220V, Industrial 380V. Distribution: 10 000V, up there 35kV, 110kV, 220kV, 330kV, 500kV, 750kV, 1000kV. Frequency: 50 HZ.
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:Switching power supply S-120-12 monitor dedicated 12V / 10A camera power supply how to meet the amount of power
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:Industrial electricity in the DPS.UPS, etc. are temporary power to Caesar ah
DPS is the power of the equipment being tested, UPS is uninterrupted power supply,
Q:What is the allowable fluctuation range of the industrial standard power supply 380v power supply voltage?
10 kV and below three-phase supply voltage allowable deviation of 10% for nominal system voltage. 220V single-phase supply voltage to allow the deviation of the standard system voltage +7%, - 10%. Users who have special requirements for the allowable deviation of the supply voltage shall be determined by the agreement between the parties.
Q:Apple 4s dedicated mobile power are what?
5) to see product charge management, 6) see compatibility, 7) to see the characteristics of the product features, 8) to determine the positioning of the purchase of products, 9) Note the weight of the product.
Q:Is the industrial atomizer good with a switching power supply or a toroidal transformer?
Not need long-term online work of industrial instruments, naturally use the switching power supply is better.
Q:Do you want to use the DC24V of the alarm system for the power cord of the bus-specific fire-fighting telephone?
1, the bus system of the fire telephone extension or telephone jack is no need for external power supply, through the fire telephone bus directly access the fire telephone controller. But the fire telephone controller (usually with the alarm controller set disk) requires DC24V power supply, and by the fire alarm controller to provide;
Q:What is the best industrial power industry?
haoyang Power The key is to see what you use in the occasion, you need the power of the accuracy requirements of how high
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.
