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: 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: 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: Electrical equipment classification
- Electric power system in a lot of power equipment, according to their role in the operation of different, usually divided into electrical equipment and electrical equipment two times. Directly involved in the production, transformation, transmission, distribution and consumption of electrical equipment called electrical equipment
- Q: In order to ensure the normal operation of the power system and equipment to achieve a grounding
- 2) protection of grounding: is the electrical equipment in normal circumstances, such as metal parts, such as metal shell, structural frame and the earth to make metal connection. In order to ensure personal safety.3) security is zero: is the electrical equipment in normal circumstances without the metal part of the system and the zero line connection to avoid the risk of electric shock. For three-phase four wire system of electrical equipment, must adopt the method of security zero.
- 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 specific enterprises and units are used to test the power of the equipment ah
- The other really did not ~ ~ ~ ~ ~What do you mean by electrical testing equipment??? High? Low?
- Q: What are the two devices in the power system
- . Such as measuring instruments, relays, switches, buttons, automatic control equipment, computers, signal equipment, control cables and some power supply devices, etc..
- Q: What is the redundancy of electrical equipment
- Disk duplex: a I/O controller is added to the mirrored disk to form a dual disk to improve bus contention.RAID: cheap redundant array of disks (Redundant array of inexpensive disks). As the name suggests, it consists of a number of disks, through a controller to coordinate the movement of a single data flow into the disk. The RAID3 system consists of 5 disks, in which 4 disks store data, and the 1 stores the check information. If a disk fails, you can replace the disk on the line, and through the other 3 disks and check the disk to re create the data on the new site. RAID5 will check the information distributed on 5 disks, so you can replace any disk, the rest with the same RAID3.
- Q: Ask the expert about the design of the power system diagram, 6kV side of the electrical equipment how to supply
- 6kV equipment directly in the 6kV bus out of the lead, do not consider the capacity, it does not affect the use of 380V equipment
- Q: Power equipment is required to replace the dimension, the state has no relevant provisions
- This depends on the provisions of the local power supply department, generally not mandatory requirements.
