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:What are the necessary equipment for power line project?
- First of all to have safety equipment, such as an electroscope, grounding wire, personal security line, an insulating rod, a nuclear phase device etc.
- Q:Ask the expert about the design of the power system diagram, 6kV side of the electrical equipment how to supply
- For 35/6KV step-down stationEach line with the 6/0.4KV transformer, or 6KV equipment (such as 6KV synchronous motor), are the load of the stationSo, there are 6KV devices, single occupancy 6KV bus on a certain line can be
- Q:The difference between electric load and power supply capacity
- There is a correlation coefficient between them, the power supply capacity = power load * demand coefficient.
- Q:What are the effects of frequency variation on power users and power systems?
- 1, the use of motor speed and system frequency, the frequency change will make the motor speed change, thus affecting the quality of the product. For example, the textile industry will change because of the frequency of defective products.2, modern industry, national defense and science and technology have been widely used in electronic equipment affected by frequency.System itself:1, low frequency operation, the generator will be affected by the stress of the blade. Even cause resonance, reduce blade life.2, increase the excitation current, improve the temperature rise, etc..
- Q:Maintenance of electrical equipment, security measures to ensure that what
- 0, in the maintenance of the unit, the unit of the internal control components, need special inspection, is strictly prohibited to open the electronic control box.11, the unit test, in the control panel of the unit, the unit before and after cutting motor direction of head and tail of each station by one person to start and stop the operation, before the test, first of all to carry out safety checks on around the unit, after confirmation, can operate.12, in the maintenance of the power supply system, first put the cooling water system, can be maintained, so as not to cooling water into the power system.13, in the maintenance of power equipment, to check the integrity of the electrical equipment and flameproof performance, so that each equipment to meet the requirements of the standard and explosion-proof. 14, any kind of relay protection device failure, power equipment shall not be put into operation.
- Q:Complete sets of power equipment life of the country what are the provisions for the aging of the equipment how to deal with, there is no standard?
- Such as frequency of use, load characteristics, working environment, etc.. The service life of a certain type of equipment must refer to the specifications of the corresponding industry.
- Q:Withstand voltage test, power equipment insulation unqualified reasons?
- Voltage test, power equipment insulation failure may be due to: insulation deterioration. Such as transformer oil into the water, solid insulation moisture, insulation aging, etc., will lead to decreased insulation performance, in the pressure test may not be qualified.
- Q:What are the technical measures to ensure the safety of the power line equipment?
- 1 blackout.2 electrical inspection.3 grounding wire.4 use personal security line.
- 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:In the communication and power equipment in the data access to a "remote message quantity" concept, then what is called "remote information", how to define it? Thank you
- Remote signal to speak a little bit is the alarm signal, switch position signal to the control room
