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
- In accordance with the provisions of the "power supply business rules," article forty-sixth: user owned, joint ventures or fund-raising construction of transmission, substation, distribution and other power supply facilities, the operation and maintenance management to determine the following provisions:
- Q:Is there a warranty period for power equipment?
- Warranty period is not specified, is determined by the relevant test standards
- Q:Electrical equipment classification
- Mainly there:Equipment for the production and conversion of electrical energy, such as generators, motors, transformers, etc.;Switch on or off circuit breaker, such as circuit breaker, isolating switch, contactor, fuse, etc.
- 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!
- This is a bit of a problem, because there are different levels of insulation in the neutral grounding system. Some places are determined in accordance with the graded insulation, that is, the first and the end of the neutral point of the different requirements
- Q:What is the specific name of the double name of the equipment in the electric work sheet? Know please enlighten me.It would be better if you had a sample ticket.
- Each power device has a Chinese name and numberSuch as: Zhang Road 905 switch, Zhang road is his Chinese name, and the 905 is his numberThe line is the same
- Q:Electric power automation equipment
- Power grid dispatching automation, power system analysis and control, power electronics, power market, distribution automation,
- Q:I would like to set up a power engineering Co., Ltd., do not need to know what the scope of business
- Do not need to be able to do anything! Or you can hang on to someone else's qualifications!
- Q:What is the installation equipment of the transformer on the power installation project
- Installation of drop fuseHigh and low voltage side of distribution transformer should be equipped with fuse. High voltage side fuse at the bottom of the vertical distance from the ground is not less than 4.5m, the fuse and the horizontal distance of not less than 0.5m, in order to smooth down the fuse tube is easy to operate and fuse, axis drop type fuse with the vertical line of 15% ~ 30% angle. The vertical distance to the surface of the bottom of the low voltage side fuse shall not be less than 3.5m, and the horizontal distance of each fuse shall not be less than 0.2m.
- Q:On the safety hazards of electric equipment safety
- 1 prohibited in the overhead power lines on both sides of the area within 300 meters of flying kites. If the illegal flying kite behavior should be stopped at the first time and report to the power sector or local government.2 no unit or individual shall plant trees, bamboo or other tall plants that may endanger the safety of power facilities in the power line protection zones.
- Q:In what way is it confirmed that the destroyer is an electrical device? Identification or what.
- Not yet installed agricultural low-voltage lighting circuit, not in the use of electrical equipment. Even if the person who took part in the erection of the wire, it will not cause harm to public safety, its behavior should be qualitative theft.
