Product Description
Description:
GK4835A/50A is a communication PV controller module with MPPT function and converts the energy of solar modules into the stable DC to power the load or charge the battery. It is mainly used in the mobile communication base stations and the communication equipment of machine room and remote independent power supply station. This product adopts DSP control technology, and the DC output is regulated in the isolated and independent way. The module can form the smart wall-mounted or cabinet power supply system of communications. Smart control system can adjust its output parameters and protection value through the serial port communications, with the smart battery expert maintenance and management system.
Features:
High conversion efficiency with MPPT automatic tracking function;
With the wide input voltage range, it is applicable to the modules with different capacities;
Precise DC output voltage / current and small ripple;
Charging is performed by the smart current limiting to increase the battery life;
PV reverse polarity, input over-voltage/under-voltage protections; battery high/low-voltage protection; output short circuit protection, etc.;
Minimized module has hot-swapping function with easy maintenance and installation;
It can perform 485 communication with the host computer with MODBUS protocol.
- Q: 1 what is the power system and the power network? 2 what is the rated voltage of the electrical equipment? Why do the power system to use a variety of voltage levels? 3
- The electric power network is referred to as the "power grid", which refers to the connection between the bus from the booster station of the power plant to the bus of the substation.
- Q: The insulation level of the electrical equipment in the neutral grounding system shall be consideredA. phase voltage;The square root of 2 phase voltage B.;The square root of 3 phase voltage C..Great God in the end this election? I am very tangled!
- For example, 220kV transformer (YNYnd11) insulation level high voltage side is LI950AC395-LI400AC200, the front half part (head) of the lightning impulse voltage and power frequency withstand voltage were significantly higher than that of the second part (neutral side). According to the power frequency withstand voltage needs to achieve 1.6 times the rated voltage requirements, the first end of the line voltage is considered in accordance with 220kV, the neutral point according to the phase voltage (127kV) considerations. But there are some places are fully insulated, that is, according to the line voltage calculation.The triangle connection must be considered by the line voltage. Overall, C is definitely right.
- Q: The problem of electric power equipment withstand voltageWhy does the pressure decrease when the altitude is high? The air is thin, is not easy to breakdown (vacuum breakdown is not very low atmospheric pressure)
- Although the degree of vacuum is higher than that of the low altitude, the relationship between the insulation strength and the degree of vacuum, especially from the atmosphere to the beginning of the high vacuum. Insulation strength is high - low - high change process
- Q: What is the meaning of the high - voltage high - voltage device in power system, which is mainly used to protect the equipment and equipment
- The high cycle is high frequency, rated frequency of power system in China is 50Hz, the normal range was 49.8~50.2Hz, under normal circumstances, the power dispatching department through power planning, automatic control and other means to achieve power generation and load demand power balance. In the event of an accident, the balance can not be controlled by these means,
- Q: How to solve the short circuit of emergency communication equipment
- Usually you see the white plate, marked with "national emergency communications," the license plate, if the following is the letter "B" at the beginning of the China Radio Association members
- Q: How to strengthen the management of electric power information communication equipment
- Problems in the management of information communication equipment1 personnel structure is not reasonable. With the continuous expansion of the power grid, power information communication equipment is also increasing. But at present, there are some problems in the management of electric power communication equipment, such as the lack of professional staff and the lack of post. At the same time, due to the lack of post phenomenon, resulting in the equipment management and maintenance work in the process of increasing the workload, making the existing staff complaints, work quality and work enthusiasm can not be guaranteed. On the other hand, because the new staff less power communication professionals confidence aging trend is more and more serious, the personnel structure imbalance restricts the progress and development of electric power information and communication equipment management to a great extent.
- Q: All I know is a generator, a transformer. I also want to fully understand the power system related to the equipment, from power generation to end users (enterprises, factories, they will design the equipment, production equipment is not to say, but they will be transferred to the electricity, in use is the processing equipment, such as transformer, I only know this involved) equipment, detailed list, thank you ah
- Two equipment: all kinds of relays, switchgear, PLC and other control equipment.The power plant and substation: electric energy metering, remote device (RTU monitoring and high frequency cutting machine), relay protection equipment (generator, transformer, bus lines and other equipment such as protection, differential protection, distance protection, over-current protection, earthing protection), automatic line monitoring device, are now in microcomputer protection the equipment.Enterprise side: the control of power supply system, DCS distributed control PLC programmable control; relay protection equipment (mainly over current protection); reactive power compensation cabinet overvoltage protection, reactive power compensation cabinet intelligent control components.
- Q: Electric power equipment start-up and commissioning of the project there is a difference?
- The start of the equipment is started in the single test.
- Q: What is the power plant
- Is to do the preparation of electricity ahTransformer transformerSmall to power switch, etc.
- Q: What is the redundancy of electrical equipment
- I/O card: to the server, mainly refers to the network card and hard disk control card redundancy. Network card redundancy is inserted in the server dual network card. The card was large and redundant technology medium on technology, now has been owned by the PC server. PC server such as Micron's NetFRAME9200 up to 4 network card redundancy, the 4 network card each bear the network traffic of 25%. COMPAQ all ProSignia/Proliant servers have fault tolerant redundant dual nic.
