Product Description:


Application Scope

The HF DC power supply is of high efficiency and reliability, which is specially developed for the Kyropoulos sapphire furnace and it, is with merits of high power factor, low harmonic current and high efficiency.

Product Principle

Combining with the control concept of current international mainstream, the heating power supply adopts the digital design to make the machine run more efficiently.

The heating power supply adopts the N + 1 redundancy technology to ensure the entire sapphire production cycle. We adopt DSP digital control mode, making the output voltage accuracy to five over ten thousand, and it has analog peripheral interface, 485 communication interface, etc. Using IGBT as power device to improve working efficiency and conform to the current trend of saving energy and reducing consumption.

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:EPS emergency power supply and DC screen is one thing, what is the difference between the two?
Mainly used in road traffic lighting, venue lighting, building fire escape lighting, fire pumps, spray pumps and other fire equipment to provide emergency power supply, EPS fire emergency power supply through the CCC China national compulsory product certification, the current state through the 3C certified EPS Fire emergency power supply size is 0.5KVA to 110KVA. EPS fire emergency power supply can be divided into emergency lighting, hybrid and power inverter EPS emergency power supply three categories.
Q:What brand of power control module is better? You know MINMAX and C & D two brands.
See you want to DC or exchange. DC power personal feel that Siemens is very good.
Q:US Industrial Electricity Voltage
3. Motor rated voltage: 115V, 230V, 460V and so on. Lighting rated voltage: 120V, 240V and so on. US industrial electricity for the three-phase four-wire 227V / 480V; civilian is a single-phase 3-wire system 120V 60HZ (working zero line and the protection of the zero line is separate). In China, long-term single-phase second-line and three-phase four-line to the residents of power supply, industrial, civilian mixed in a system, a great interference. The United States, Japan, the United States some countries are single-phase three-line to the residents of power supply, and industrial systems are separated.
Q:Computer power can be inserted in the air conditioning dedicated socket
It should be noted that the air conditioning sockets are 16A / 250V specifications, jack distance greater than the ordinary 10A / 250V socket, so the computer power plug must be replaced by 16A socket can be inserted into the air conditioning socket. Therefore, the computer power plug in the use of air conditioning socket is possible.
Q:Do you need a separate dedicated power supply for each color dome camera?
There are two ways to power the camera 1. Separate power supply 2. Power supply (power supply needs to match the power of the load)
Q:PIC microcontroller used in the industrial field, the power supply using switching power supply plus B0505 isolation module, anti-jamming performance is better
Certainly better, or else else to develop this power module why? All with a direct switch power supply! The
Q:Apple 4s dedicated mobile power are what?
Charging Po has 5V / 2A charge output, 5V / 1A charge output. 2, Apple 4S use 5V / A charge output. 3, selected by the polymer lithium battery as a storage unit.
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:Industrial instrument power supply with a good switching power supply or transformer
Industrial instrument power supply with a good switching power supply or 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. In the case of large fluctuations in the power supply or industrial equipment is 24 hours long-term need to supply the case, the use of transformer power supply more reliable, because it is very skin and difficult to damage. The switching power supply is cheap, the use of low cost, power efficiency relative to the transformer power supply high. Not need long-term online work of industrial instruments, naturally use the switching power supply is better.
Q:Industrial electricity (380V) what the color of the wire, which is the line of fire, which is the zero line
30KW current about 60A or so, calculated by P = ui to calculate, mainly to consider the line voltage and phase voltage conversion, 380V should be replaced by phase voltage.   60A of the meter generally do not have to consider the installation of a more current transformer, 75 / 5A on the line, so that the secondary current in the 4 amps, the meter with 5A on the line, calculate the power when remember to multiply 15 times.
