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 is the meaning of the high - voltage high - voltage device in power system
There has been greater than the power load power requirements, response to the power parameters is high frequency, this requires high cycle splitting device, tripping the corresponding circuit breaker, to remove the part of power grid connected or separated from the original into two or more power to lift the accident or the narrow scope of the accident to
Q:Is the GIS in the electric power high voltage switch cabinet
GIS is a shorthand for two conceptsThe 1 is the geographic information system.2 refers to the (GAS INSULATED SWITCHGEAR) gas insulated fully enclosed combination of electrical appliances, closed inside the main circuit breaker, isolation switch, grounding switch, bus, lightning arrester, etc.. Many power plants, substations, switching stations are made of GIS, so that the small footprint, or maintenance. With the high voltage switch cabinet or not.
Q:What is the importance of annual maintenance of electrical equipment
What is power equipment testing? Why detect? How to detect? This paper will focus on the solution of the problems of the electric power users, especially the high voltage self control households. Hope to be able to push the pressure from the heart of the door of the fog, accurately understand the concept and scope of detection, a correct understanding of the importance of power equipment testing, in-depth understanding of the detection technology, power safety in the case of unburned.
Q:In order to obtain the qualification test of electric equipment
The provincial electricity supervisor application; can only apply for five (10KV and below) or level Four (35KV and below) qualification, the first level of qualification can only apply for the first four to rise
Q:What is the GIS in power system
GIS has the advantages of small footprint, high reliability, high security, maintenance workload is very small, the main parts of the maintenance interval of not less than 20 years.In the Three Gorges project, the left bank power station and the right bank power station has a 550 thousand volt GIS high voltage power distribution device. Left bank power station 550 thousand volt GIS and ancillary equipment in the upstream of the Deputy plant height of 93.6 meters GIS indoor. Main transformer and 500 thousand volt shunt reactor. GIS and the main transformer and shunt reactor with oil, six sulfur hexafluoride casing connection. Room GIS upper Deputy plant roof, layout of a GIS air, oil outlet pipe and open the trap, capacitor voltage transformer, lightning arrester, air outlet, six sulfur hexafluoride overhead line connected by the casing with these devices. GIS indoor type.Indoor GIS is hardly affected by atmospheric conditions. GIS overhaul cycle is generally 15 years or more, the Three Gorges power plant GIS main parts of the maintenance interval of not less than 20 years. And AIS or H - GIS, due to the impact of the external atmospheric conditions, the aging and damage speed, overhaul cycle is short and overhaul times.
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:How long has the power of power electronic equipment delivered water
; equipment (mainly separator population) and pipeline (mainly elbow) wear faster, if the design, construction or improper operation, is easy to cause material deposition, so that the conveying jam, interrupt; transportation should not be high humidity, viscous or easily broken material etc..
Q:Electric power automation equipment
Construction and transformation of rural power grids, power plants, power plants, environmental protection, automatic control and integrated automation of nuclear power plants, technical management, etc..
Q:The role of electrical equipment handover and preventive testing
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: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.
