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 best industrial power industry?
Under normal circumstances, Chaoyang power supply accuracy, ripple factor, can meet the industrial use
Q:What brand of power control module is better? You know MINMAX and C & D two brands.
Look at your main application. If cheap cheap goods, everywhere, a search on the Internet, a lot. But the quality of good and bad, you have to grasp yourself.
Q:PIC microcontroller used in the industrial field, the power supply using switching power supply plus B0505 isolation module, anti-jamming performance is better
You use the PIC with which models, switching power supply to the chip power supply is no problem, the key is to single-chip power supply filter to do a good job. Relay output to use optocoupler isolation and so on. B0505 output test must have a small load and input and output must be added filter capacitor, otherwise interference is great.
Q:Industrial electricity (380V) what the color of the wire, which is the line of fire, which is the zero line
Zero line of fire: zero line Fire line refers specifically to the power supply lines, electricity supply voltage of 220 volts (V). It includes a zero line [N] and a fire line [L], zero line ground (ground is zero) so called the zero line. FireWire, is the circuit power transmission line. Zero line, mainly used in the working loop, from the transformer neutral point after grounding lead the main line.
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:Site with industrial power 380V / 50hz, electrical equipment is 110v / 60hz. Is there a solution?
Voltage problem, 380V three-phase power, 110V should be single-phase power,
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:Military grade power supply, industrial power supply, civil power supply where the difference?
Military-grade power supply, demanding, such as waterproof, fire, drop and so on are required,
Q:My magnetron is used in the industry, my dedicated power to start less than 2 minutes to stop,
This reason is much better, next to the investigation 1 heat problem magnetron with or without cooling fan, generally if there is no cooling or cooling broken, then the magnetron will work for 2 minutes to burn, you measure the same as the filament is passed. Burn is a magnet cracking
Q:Emergency lighting should not take fire special power supply, right?
2 .. Building 7 # 8 floor, if the normal power supply from the time when the fire if the fire is not strong, it is likely to cause short circuit problems may cause sparks, leakage, etc., so fire Personnel will be more trouble. Why should fire strong cut
