1, Product  desciption

                                          

Inverter circuits designed to produce a variable output voltage range are often used within motor speed controllers.

The DC power for the inverter section can be derived from a normal AC wall outlet or some other source. Control and feedback circuitry is used to adjust the final output of the inverter section which will ultimately determine the speed of the motor operating under its mechanical load.

Motor speed control needs are numerous and include things like: industrial motor driven equipment, electric vehicles, rail transport systems, and power tools. (See related: variable-frequency drive ) Switching states are developed for positive, negative and zero voltages as per the patterns given in the switching Table.

The generated gate pulses are given to each switch in accordance with the developed pattern and thus the output is obtained.

 

2, Features of  the  product

 

Inverters convert low frequency main AC power to higher frequency for use in induction heating.

To do this, AC power is first rectified to provide DC power. The inverter then changes the DC power to high frequency AC power. Due to the reduction in the number of DC Sources employed, the structure becomes more reliable and the output voltage has higher resolution due to an increase in the number of steps so that the reference sinusoidal voltage can be better achieved.

This configuration has recently become very popular in AC power supply and adjustable speed drive applications. This new inverter can avoid extra clamping diodes or voltage balancing capacitors. There are three kinds of level shifted modulation techniques, namely:

 

 

 

The first thing to figure out is the length of road in need of street lights.

This can be a small entrance road only a couple hundred of feet long to miles of streets through an area. Does the area currently have any type of lighting available.

 What is the reason for needing street lights in this area

 

 

Is the electrical grid already nearby or would you need to call in the power company to bring in electrical lines.

 If the electric needs to be brought to the area, how much is this going to cost? Depending on how far the grid electric is from the location of the needed lighting, this can be quite expensive.

 

 

How much lighting is needed on the street? Do the lights need to be dark sky compliant.

Do the street lights need to run from dusk to dawn or for only a specified number of hours at night.

Are the street lights able to dim in the middle of the night and still provide enough lighting.

These questions need to be answered before you can decide on how many lights you will need to complete the project.

Q:Solar panels for solar panels
The use of a single chip and special software to achieve the intelligent control; the use of battery discharge rate characteristics of the correct discharge control. The discharge voltage is controlled by the discharge rate curve of the control point, eliminating the simple voltage control overdosed inaccuracies, consistent with the inherent characteristics of the battery, that is, different discharge rates have different end voltage. With overcharge, over discharge, electronic short circuit, overload protection, unique anti-reverse protection and other automatic control; the above protection does not damage any parts, do not burn insurance;
Q:How to debug a solar street light controller
Manual mode (5 ·): In this mode, the user can press the button to control the load on and off, regardless of whether it is during the day or night. This mode is used for some special loads or when used for commissioning.
Q:What is the meaning of the DC load above the solar controller?
Can be batteries, lights, motors and other DC equipment can be used
Q:Solar controller 10a, a represents what
A, represents the current. Indicates the current that is allowed to pass during operation of the controller.
Q:How the solar controller wiring,
Controller (English name: controller) refers to the order in the order to change the main circuit or control circuit wiring and change the circuit resistance value to control the motor start, speed, braking and reverse the master device. It consists of a program counter, an instruction register, an instruction decoder, a timing generator and an operation controller. It is a "decision maker" that issues a command to complete the coordination and command of the operation of the entire computer system.
Q:Solar controller red light flashing
Solar controller is divided into a variety of types, the lights are also representative of the battery, battery components and load, you said the red light flash is the end of the indicator light. You can also look for the controller's instructions, the above will generally refer to the reasons for the light flash.
Q:Choose a solar controller which need to have a few conditions
To buy a solar controller must know the power of the solar panel and the load power to be used to determine the controller's charging current and discharge current. General solar controller are 12v / 24v automatic identification. Discharge current = load power / 12v, charge current = battery power / battery board voltage. The voltage of the panel can be set with the multimeter DC. The short-circuit current of the panel uses a clamp meter to test the current. So the battery power = voltage * current, basically know the power of the solar panel. The battery charge current will know. The current range of the controller is greater than the charging current of the solar panel and the discharge current of the load.
Q:What brand of solar controller is good
In today's solar industry, brand-name products in terms of quality to after-sales service, are guaranteed. And consumers want to compare through their own observation to choose, there are some difficulties. Such as the key components of solar water heaters is the insulation of the tank and the material and thickness of the liner steel, only the water tank can be destroyed before the amount of liner thickness and material. There is the quality of the vacuum tube, these things even if our industry people, without destroying the product, do not use precision instruments in the case, can not be identified
Q:What is a solar controller?
The controller is the microcomputer on the water valve above the show solar water tank temperature control Sheung Shui to a certain level of electronic valve will automatically shut down the water is not on the water level to the most electronic valve will automatically open the solar water tank temperature is higher than 75 degrees above the water tank That is, no water, the electronic valve will not open to avoid solar vacuum tube break
Q:Solar controller use
The controller as a core component of solar energy must be a reliable product, otherwise no matter how good the solar system can not play its due role.
