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:US Industrial Electricity Voltage
2. Requirements for "Scope A": 115 ~ 120V System: When lighting: 110 ~ 125V of electrical equipment; power supply point 114 ~ 126V. No lighting: electrical equipment at 108 ~ 125V; power supply point 114 ~ 126V. 460 ~ 480V system: (including 480 / 277V three-phase four-wire system) When lighting: power equipment at 440 ~ 500V; power supply points 456 ~ 504V. No lighting: electricity equipment at 432 ~ 500V; power supply points 456 ~ 504V. 13200V system: power supply point 12870 ~ 13860V.
Q:Industrial switching power supply which brand is good, including imported.
Japan LAMBDA Taiwan Ming Wei switching power supply (MW) MEANMALL Shanghai Heng Fu switching power supply (HF) Shanghai Lan Fu switching power supply (LanFu) Chaoyang Power Jinwei source power supply Nuclear in the pass Japan Kosovo Siemens
Q:Meizu special mobile power is which brand?
In fact, that KINI mobile power, rest assured that the use of, really bad.
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:Why do you need to use isolated power in industrial communications?
In simple terms, the need for isolation mainly involves: communication equipment on the power of the stability and anti-interference requirements are high,
Q:Industrial control system power supply Why is the choice of DC24V power supply? Why not 17V? 11V?
regardless Is 2V lead-acid battery or commonly used 1.2V, 1.5V, 3V battery are good combination. With a series of standards to be in a timely interchangeable thing.
Q:Dell 9020MT business computer can only use 290W dedicated power?
Yes. Dell 9020MT i7 version of the power supply is rated at 200W. 290w on the super. The rated power is the power at which the appliance is operating normally. Its value is the rated voltage of the appliance multiplied by the rated current. If the actual power of the appliance is greater than the rated power, the appliance may be damaged.
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:Fire emergency lights and evacuation signs need to receive a dedicated fire power on it?
If connected to the fire power, because the fire power is uninterruptible power supply, it will appear in the power failure can not be lit and lose the proper role. Indicator signs for the bright signs, generally also with a battery inside, also need not be connected to the fire power.
Q:My magnetron is used in the industry, my dedicated power to start less than 2 minutes to stop,
3 power matching problem If you choose the magnetron power is lower than the lamp, the same point is not lit or strobe 4 waveguide shade design problem if you have mature technology this can be discharged
