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: Recently went out to do the test, do not know the difference between the two tests
- Is your company product acceptance test of customer delivery, in order to find new equipment in the design, manufacture, transportation and installation in the process of diagnosis is consistent with the risks, operational conditions, testing of new equipment.
- Q: When a fault occurs in power system, the circuit breaker tripping device near fault
- When a fault occurs in power system, the circuit breaker tripping device near the fault, in order to reduce the power outage, this is the relay protection ().A, selective B, reliability C, sensitivity D, non selectivity
- Q: In what way is it confirmed that the destroyer is an electrical device? Identification or what.
- Electricity has been used, but due to the lack of dry season or lack of electricity and other reasons, and the suspension of power supply lines, should still be considered to be in use. The behavior of the people to cut such lines in the cut, if a crime, shall be held criminally responsible for the destruction of electric power equipment.
- Q: What is the meaning of the high - voltage high - voltage device in power system, which is mainly used to protect the equipment and equipment
- The high cycle is high frequency, rated frequency of power system in China is 50Hz, the normal range was 49.8~50.2Hz, under normal circumstances, the power dispatching department through power planning, automatic control and other means to achieve power generation and load demand power balance. In the event of an accident, the balance can not be controlled by these means,
- Q: How to solve the short circuit of emergency communication equipment
- , a number of amateur radio enthusiasts, radio license, the application of their own call sign plate, usually just play the role of decoration,
- Q: Part of the rated voltage of the power equipment is marked 10.5kv, and this is similar to the label 10KV power equipment what is the difference?Consulted a lot of teachers, but it is said that this is the old and new two methods, I would like to ask what is the basis of this, it is best to have a national standard for reference
- Here are a few concepts, you can check1, the network voltage, is the line or the rated voltage of the bus, which is usually said to be rated voltage, including 3, 6, 10, 35, 110, 3302, rated voltage generatorThe rated voltage of the generator is usually 5% higher than the rated voltage
- 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
- General electric power on the four remote, remote, telemetry, remote control, remote control, and now there is more than one remote viewing. Remote signal is generally refers to the opening and closing state of each switch, remote measurement is the voltage, current, temperature, etc..
- Q: The difference between electric load and power supply capacity
- The coefficient of demand is a comprehensive coefficient, which indicates that the ratio of the actual power taken from the power supply network and the power of the power equipment group. That is, your equipment can not be run at the same time, it is impossible to run at full capacity, as well as line power efficiency, power equipment in the actual operation of the power efficiency and other related. In fact, it is difficult to determine the above coefficients for a group of electrical equipment, not to mention the operator's proficiency, the supply of materials, tools, such as the quality of random factors have an impact on. So we can only depend on the measurement statistics.
- Q: Withstand voltage test, power equipment insulation unqualified reasons?
- Test methods and voltage measurement methods are not correct. For example, when the transformer is tested, the non - Test winding is not connected to the ground, and the non - tested winding may be discharged to the ground. For example, the test of large capacity test, the voltage is still on the low side of the measurement, due to the capacitive effect, the actual increase in the voltage on the test sample over the test voltage, resulting in the breakdown of the subject matter, misjudgment is not qualified.
- Q: For example, EPS emergency power supply and so on, as well as those used in public emergencies.
- High / low voltage switchgear, power distribution cabinets, industrial ovens, constant temperature and humidity test box, ovens, air curtain machine (invisible door), inductive automatic door, air conditioning and industrial fans, NELL thyristor module, thyristor, single / three-phase bridge rectifier, fast recovery module
