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 lightning protection measures of power system
- Power system lightning protection is to prevent the atmospheric overvoltage.The specific measures to prevent the atmospheric overvoltage are: to set up the lightning rod above the high-voltage line (to prevent direct lightning). Install lightning rod (lightning, lightning protection) at the equipment to be protected.
- Q: What is the installation equipment of the transformer on the power installation project
- Installation of lightning arresterMost of the external factors that affect the operation of distribution transformers are from lightning accidents. Therefore, the transformer equipped with lightning protection devices, should be used in the synthesis of metal oxide arrester without gap insulation, the power frequency voltage withstand capability, good sealing, protection characteristics.
- Q: On the nameplate of the electrical equipment, what does ith UE ie mean?
- Electrical equipment consists of two parts: power supply and power equipment. The power supply comprises a storage battery, a generator and a regulator thereof. The utility model comprises a starting system of an engine, an illumination, a signal, an instrument, etc., and also comprises an ignition system of the engine.
- Q: Private enterprises must be free transfer of power facilities
- The new user electrical facilities investment, after the investment asset is transferred to the power supply enterprise, according to the need for "business rules", the actual state of electricity contribution, interface division, maintenance management ability, after consultation by both parties to determine.
- Q: In order to ensure the normal operation of the power system and equipment to achieve a grounding
- 1) work: grounding is to ensure electrical equipment in normal or accident conditions reliably, the neutral point directly or through special equipment (such as Petersen coil, reactor, resistance, breakdown insurance, etc.) do metal and earth connection.
- Q: Generator, shunt capacitorShunt reactorShunt capacitorStatic compensator
- The power supply in the power system is a three-phase sine alternating current generated by the generator, in which there are two kinds of electric power.
- Q: Electric power equipment includes what steam turbines are used in what areas of what companies need steam turbines
- Power equipment including: boiler, steam turbine, pump, deaerator, condenser, generator and so on, from the impact of steam boiler turbine blade hot out of the turns, then drives the generator to rotate to generate electricity, in general, now in thermal power plant and a large Shipping Co to use steam turbine
- Q: How long has the power of power electronic equipment delivered water
- Pneumatic conveying device has good dustproof effect; easy to realize mechanization and automation, reduce labor intensity, saving manpower; in the transport process, can be a variety of technology operations at the same time, such as mixing, crushing, sorting, drying and cooling; to prevent the material moisture, pollution or mixed with debris and other advantages, so it has been applied in the casting department, metallurgy, chemical, building materials, food processing etc.. Its main disadvantage is that the power consumption is large
- Q: I would like to ask the power experts, according to the annual additional electricity, installed capacity, how to calculate the amount of the necessary supporting power equipment, etc.?
- At least the national research institutions to do, here is about not a conclusion. If such a conclusion, it also belongs to the commercial classified data, not just to show people.
- Q: What are the two devices in the power system
- Connect the two device circuit, called the two line. In the two line of DC is generally used for communication detection equipment, such as PABX, PDH, MUX, generally for 48V DC power supply, AC line for AC equipment use
