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:Private enterprises must be free transfer of power facilities
- The new user electrical facilities investment, after the investment asset is transferred to the power supply enterprise, according to the need for "business rules", the actual state of electricity contribution, interface division, maintenance management ability, after consultation by both parties to determine.
- Q:No concentrator can be copied directly
- There are two types of remote meter reading devices in electric power generation: one is low voltage set, called concentrator, the other is called terminal. The concentrator role is the number of meter data, first by the carrier or 485 communication way to collect the equipment, and then through the cable (optical fiber) or wireless network (cdma/gprs) transmitted to the main station.
- Q:Reactive power compensation methods commonly used in power equipment
- Hello!Electrical equipment commonly used in reactive power compensation and the method of improving power factor are: synchronous motor, synchro, series capacitor compensation, shunt capacitor and series reactor compensation (EHV transmission line) and SVC, SVG compensation. SVG is through the power electronic device IGBT and its control circuit, a active VaR of equal amplitude and opposite to the size of the system, the reactive power compensation device for reactive power compensation to offset the system in recent years is the development direction of reactive power compensation.
- Q:Rivers and lakes emergency, there is a 110kV and 10kV power supply line works, I would like to ask this kind of power project warranty items, scope, life and other detailed provisions where can be found? Are there relevant regulations? For example, if the provisions of the housing construction warranty, you can check the "construction quality management regulations," but the warranty content of power projects, what information should be checked? Note that the warranty is not repair. Waiting for good people reply, satisfaction and then points.
- This is not the regulations of state Power Grid Corp to their line of work area to do some local line area for engineering team to do is sign the contract established general warranty of 1 years seems to include tower structure, grounding resistance, line fitting, a line on what channel estimation problem in within the scope of the contract
- Q:I would like to open a company on the construction of power equipment, what needs to be prepared? (including qualification level, capital requirements, etc.) the more detailed the better
- The second is the power facilities installation, repair and testing qualification. Also divided into one to four, respectively, by the State Electricity Regulatory Commission, power supervision bureau and the city in the county, the county's dispatched office - to do the examination and approval of the electricity office. In some places there may be five, is designed for the establishment of the company.As for the size of the funds, different levels of economic development, the requirements are different, only to the location of the business sector consulting.In the actual participation in bidding and other construction activities, be sure to carefully read the tender documents and other construction projects, different projects for different requirements of different qualifications.
- Q:Definition of power equipment defects
- General defectIn the short term will not be reduced to major defects, emergency defects, although the impact of the operation but can still operate.
- Q:On the safety hazards of electric equipment safety
- 4 where the demolition, the power line protection zones of overweight, lifting, drilling, piling, scaffolding and other construction work, it shall be permitted by the power supply departments, take appropriate safety measures, and can work in the power supply department under the supervision of professional staff.5 prohibit the installation of electric power facilities within the range of 500 meters to carry out blasting operations, fireworks, etc..6 prohibit fishing in the power line protection zone, in case of personal electric shock accident.7 ban on power line protection zones, such as various types of debris piled hay straw, especially prohibit piling flammable and explosive materials.
- Q:I would like to ask the power experts, according to the annual additional electricity, installed capacity, how to calculate the amount of the necessary supporting power equipment, etc.?
- At least the national research institutions to do, here is about not a conclusion. If such a conclusion, it also belongs to the commercial classified data, not just to show people.
- Q:How to handle the qualification test, what kind of power equipment
- To submit the application form for the installation of power equipment (repair, test)";
- Q:Pre checking and checking of goods in power system
- Check: the full name is a regular inspection, with the role of pre trial is almost the same as the general power system is the two equipmentGoods inspection heard, just heard of items set is the item visit orderly, convenient for production work.
