Product 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.
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:How to run a company that operates electric equipment
Or do not do other electric power equipment, but the company's other power products to pull the business on the line, at the beginning of the sale to the quality of good, and then the price is low, a long time there is profit, customers will have.
Q:What is the meaning of the station control layer in the power system
Power system (mainly refers to the substation, power plant can also) for the control of the entire system is currently divided into the station control layer and the interlayer, after the digital substation outlet,
Q:What is the meaning of the power equipment in criminal law
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:Warranty provisions for power supply lines
Implementation of electric power projects in accordance with the general agreement between the two sides agreed to the implementation of the warranty period, equipment installation and renovation works.If the contract does not specify the warranty period, the electrical pipeline.
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:Ask the expert about the design of the power system diagram, 6kV side of the electrical equipment how to supply
6kV equipment directly in the 6kV bus out of the lead, do not consider the capacity, it does not affect the use of 380V equipment
Q:What are the technical measures to ensure the safety of the power line equipment?
Electricity, electricity, hang the ground and install signage, hanging Obscuration using personal security line
Q:What equipment is needed in the national grid project
Two equipment: all kinds of protective devices, automation devices and systems, including communications equipment, computer equipment, etc.; monitoring equipment: computer, industrial television and related equipment; fire equipment;......
Q:What is the redundancy of electrical equipment
Redundant system accessories:1, powerDual power supply system is widely used in high-end server products, the two power supply is load balancing, i.e. when the system is working for their system to provide power, when a power failure, another power will bear all the load. Some server systems to achieve the DC redundancy, and other server products such as Micron's NetFRAME 9000 to achieve AC, DC full redundancy.
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?
3, rated voltage transformerRegulations, to accept the power of the primary winding, the output power of the two windings, the general, the primary winding voltage = network voltage, the voltage of the two winding due to the consideration of the loss, higher than the network voltage of 5% to 10%
