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: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:The basic requirements of the rectifier
Battery Charge Current Limit The rectifier / charger should have a battery charge current limiting circuit that limits the battery charge current to 15% of the UPS rated output capacity (KW). When the generator set is powered (when an external low voltage signal is received), the battery charge current should be limited to zero.
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:Characteristics of Electronic Rectifier and Ordinary Rectifier
After the above static measurement, check the fault components, the circuit recovery, carefully check the circuit board on the solder joints and components with or without short circuit, touch, loose, broken place. After correcting the correct power, in most cases, the fluorescent can return to normal work, but may also occur the following transformer neutral point voltage failure, should be ruled out one by one.
Q:Is the car electronic regulator and the motorcycle rectifier the same?
Regulator is more complex: electromagnetic, electronic, composite; transistor, integrated circuit, embedded, directly installed in the generators within the integrated, and so on;
Q:Full-wave regulator rectifier and half-wave regulator rectifier! Where is the difference?
The full-wave rectifier circuit flows through a rectifier device (such as a crystal diode) for half a cycle and the current flows through the second rectifier in the other half of the cycle and the connection of the two rectifier devices Of the current in the same direction (DC) through the load.
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: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:Differences between electronic transformers and electronic ballasts
Electronic ballasts can be simply modified into electronic transformers, the output of high-frequency voltage can also be converted through the Xiaoji Diode rectifier DC. There is no voltage regulator circuit, the output voltage will change with the power of the load, so this circuit is called the electronic transformer instead of switching power supply.
Q:Why is the battery connected to a rectifier
The purpose is to filter and reduce the impact on the battery, filter, reduce electrical equipment interference, so that sound more pure sound, power cleaner, reduce the impact of many devices are large power users on the battery instantaneous demand will make the battery Aging, early retirement, if there is a rectifier will have some power, electricity will not directly use the battery power, which play a protective battery, these rectifiers are basically large capacity inside the capacitor, the Internet has its own DIY.
