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 are the fire hazards caused by electricity in the server room?2 what are the fire hazards in the server room?
- Five, fire control room and electrical fire monitoring detector set over 8 independent electricFire monitoring detector six, electrical fire monitoring system settings should affect the power supply system
- Q: Under the same voltage level, the rated voltage of the equipment is not exactly the same
- And some appliances have no effect. For example: switching power supply, it can work in a wide range of voltage, the output voltage remains unchanged. It should be noted that, as long as the manufacturers in the normal operating voltage range, generally will not cause the state of work and security issues, can be assured that the use of.
- Q: Private enterprises must be free transfer of power facilities
- 1, belonging to the public nature of the public utility lines or occupy the planning corridor, by the unified management of power supply enterprises. The power supply enterprise shall reach an agreement on the operation, maintenance and management of power supply facilities prior to the handover. The power supply enterprise shall retain the capacity of the original owner in the above-mentioned agreement for the public power supply facilities for unified operation and maintenance management.2, belonging to the nature of the user, but not in the public substation power supply facilities, by the user operation and maintenance management. If the user operation and maintenance management is indeed difficult, with the power supply enterprises to negotiate, commissioned on behalf of the power supply enterprise operation and maintenance management matters related to the signing of the agreement.3, belong to the user sharing nature of the power supply facilities, by the owner of the property rights of common operation and maintenance management. If the user has difficulty in running and maintaining management, it can negotiate with the power supply enterprise to sign the agreement on behalf of the power supply enterprise on behalf of the operation and maintenance management.
- Q: Power transformers and other equipment are what units procurement bidding, all those procedures!
- Power company or Power Grid CorpElectric power company refers to the local responsible for the sale of electricity companies, both widely regarded as the local authority.The Power Grid Corp is a company that is in charge of the construction of the power grid, and belongs to a group, but is a separate company.
- Q: The company has a number of power equipment to be exported, need to go through the sea, the technical requirements of three, I would like to ask what is the three here? How to check whether the complete sets of components used to do three treatment? Please exhibitions, grateful!
- As well as protection, control, measurement and other devices are assembled in a whole cabinet, there are a number of high-voltage switchgear in power plants, substations or power distribution equipment installed after the installation of the power plant is called a complete set of power distribution equipment.
- Q: Large engineering construction (such as buildings, factories, institutions) distribution room of the power equipment as required? What's the difference? For example, some requirements never power, and some to eliminate harmonics to improve power quality, the more detailed the better the program
- And some equipment is required to use the 6kV power supply, voltage level and the load of the device determines the choice of power equipment rated voltage, current value. Building, there are generally important electrical equipment such as elevators, in the national specification clearly requires, a class, two types of load is not allowed to power outages, which long requires the use of dual power supply
- Q: What equipment is necessary on the list of electrical engineering equipment?
- MS-300D geodetic network grounding resistance tester, MS-101D anti-interference dielectric loss automatic measuring instrument, MSGK-E high voltage switch dynamic characteristic tester, MSBL-IV arrester characteristic tester and other equipment.
- Q: Hello, I would like to ask what are the main rotating equipment in the power system? What is a rotating device?
- A device with a motor can be called a rotating device. Power system mainly refers to the generator, motor
- Q: The state of power system equipment is divided into four states
- (1) running state. The isolating switch and circuit breaker of the equipment are in the closing state, and the circuit is connected between the power supply and the receiving end.(2) hot standby. The circuit breaker of the equipment is disconnected, and the isolating switch is in the closing state. (3) cold standby. The circuit breakers and disconnecting switches of the equipment are in the open position.
- Q: In power system, the general conditions for the selection of electrical equipment are
- Electrical equipment to be as reliable as possible, must be selected according to the normal working conditions and the short circuit conditions for a variety of checks (such as thermal stability check and dynamic stability check)For some equipment also need to check the special items, such as circuit breakers and fuses to check the ability to break the current, the current limiting reactor to check the normal voltage loss and bus residual voltage, etc..
