Product Description:


Power supply irreversible transmission-type silicon-controlled rectifier of KGS A / F11,12 type


This series product adopts three-phase fully-controlled SCR bridge circuit to transform AC into DC as a power supply for irreversible transmission of stepless speed regulating of DC motor drive. The device can completely replace DC generator bank and LV control panel controlled by electric machine amplifier or magnetic amplifier, and has high precision static error characteristics, good dynamic characteristics, and can speed up with constantcurrent.

The products are suitable for mining, steel and paper industry.


In addition to the main loop, this product also includes automatic control system composed of current moderate speed (orelectric cabinet voltage) closed-loop and etc with sound automatic adjustment ability, which can guarantee that the system has good steady-speed static characteristics of dynamic characteristics with high-precision, and provides electricmotor to speed up on maximum constant current, it is suitable for the equipmentsof frequent start.


The product also has more complete protection devicesof over-current, short circuit, overvoltage and fuse, etc., when a fault occurs,in addition to cutting off the main circuit power supply, the product can signalwith sound-light alarm.


The load class of products: the continuous operationof 100% rated current and the repeated short-term of 15% rated current areallowed.

Q:How does the rectifier turn AC into DC?
This control can be accomplished by applying a so-called on-load tap changer for the machine. As a typical case, the on-load tap changer controls the input AC voltage at the primary side of the rectifier transformer, thus enabling the output of the DC value to be controlled within a certain range. Typically, the on-load tap changer is used in conjunction with a saturable reactor connected in series in the rectifier output circuit.
Q:Is the rectifier pulse the better?
The current output from the rectifier can be said to be infinitely impulsive. (Specific analysis please see Fu Li Ya class pulse formula) itself is the infinite amount, does not matter more or less concept.
Q:What is the difference between rectifiers and regulators?
he rectifier is a rectifier, which simply converts AC (AC) into a DC (DC) device. It has two main functions: first, the alternating current (AC) into DC (DC), the filter after the load supply, or supply the inverter; second, to the battery to provide charging voltage
Q:What is the difference between a car voltage regulator and a rectifier?
Rectifier, the generator is the power of alternating current, simply that there is no positive and negative. And the car is basically all the electrical requirements of DC is also required to distinguish between positive and negative batteries, especially the electrical and various electrical appliances. The function of the rectifier is to convert the electric power generated by the generator into direct current.
Q:The difference between the rectifier and the inverter
Rectifier: refers to the DC power through the semiconductor, transformers and other components into the reverse process of alternating current, referred to as the inverter.
Q:Ups the role of the filter and rectifier
The Of course, active filter filtering is much better than passive filter filtering, it can limit the current harmonic components within 3%. This is basically no effect on the grid, this filter is effective but expensive.
Q:What is the difference between the regulator and the rectifier?
Thyristor regulator, also known as "thyristor power regulator" "SCR power regulator" or "power regulator". "Thyristor", also known as "SCR" (SCR) is a four-layer three-terminal semiconductor device, put it in the middle of the power supply and load, coupled with the corresponding trigger control circuit board, you can adjust the voltage applied to the load , Current and power.
Q:Full-wave regulator rectifier and half-wave regulator rectifier! Where is the difference?
The full-wave rectification before and after the waveform and half-wave rectifier is different from the full-wave rectifier in the use of two half-wave, which improves the efficiency of the rectifier, and the entire current is easy to smooth. Therefore, in the rectifier widely used full-wave rectifier, half-wave rectifier is only used in less demanding circuits.
Q:What is the difference between a rectifier and a DC / DC converter?
Rectifier is the converter current properties, DC-DC converter is adjusted to change the DC voltage
Q:Electronic ballasts and electromagnetic ballasts are different
Electronic ballast (Electronic ballast), is a ballast, refers to the use of electronic technology to drive electric light source, to produce the necessary lighting of electronic equipment. Corresponding to the inductive ballast (or ballast).
