KGVA series silicon rectifier for floating charge

This series of product ismainly applied to power plants, substations, power supply stations and othersfor battery floating charging and DC power supply for charging, and also used for other battery floating chargingand power supply for charging, the product meets the standards of GB3859 andJB/T10095.

The product uses threephase full controlled bridge rectifier wire lines, AC input is three phase fourwires, 380V, 50-60Hz.

Q: Characteristics of Electronic Rectifier and Ordinary Rectifier: The ballast is composed of electronic components, light weight, high efficiency, more energy than the inductive energy, with the lamp The racks are easy to install together.

Q: The basic requirements of the rectifier: Input current Total harmonic distortion (THD) (total harmonic distortion THD: AC current harmonic current RMS value of the fundamental component of the effective value of the percentage) 6 pulse rectifier input current THD 6 pulse rectifier full load current Should be less than 33%; using input filter can reduce the input current distortion to 10%.

Q: Buy back the electronic ballast today, want to replace the original gas discharge UV lamp driver, buy back, I found that the electronic ballast has four output lines, but our UV lamp only two wiring. Ask the supplier, they say two lines are inductance ballast,: Electronic ballast according to the different lamp and the number of output lines are also different, usually 6 lines, 2 connected to the power supply, the other four for each of the two groups of light on both ends of the lamp. But if it is a ring lamp, there are 2 lights and 4 foot of the foot, 2 lights of the lamp with the electronic ballast only four output lines.

Q: Does the car charge a battery in its own (12V) does not also need a rectifier? To their own spark plug ignition is not "rectification" to ten thousand V? So, in the generator and then a head, rectified to 48V not work? Ask the teacher. Does the car charge a battery in its own (12V) does not also need a rectifier? To its own spark plug ignition is not "rectification" ...: First 12 volts AC into 48 volts AC, which is easier. And then the rectifier will be 48 volts AC into DC. As for the power, I believe the user can master. Because even a 12-volt power supply, there is also a power problem.

Q: What is the difference between a car voltage: 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: Ups filter and rectifier, respectively, what specific role, said on the Internet filter (filter), is a device used to eliminate interference noise, the input or output filtered through the pure DC. Rectifier will exchange into DC, since the filters have been pure DC, followed by a rectifier in turn to DC? Here is more puzzled?: This filter is simple and economical, widely used by manufacturers in high-power UPS, the suppression of current harmonic components in the range of 5% to 6%, the power grid is more or less affected, if the precision Instrument, it is possible to measure the work of instability, there *, the reading is not allowed to wait for such phenomena.

Q: Why is the battery connected to a rectifier: Charging current limiting function Currently access network site is almost all use of VRLA batteries, due to the tight assembly of the battery structure, in the high current charging, will cause the battery drums even heat out of control phenomenon, it must have a battery charge current limit Stream function. Battery over discharge protection function of the battery over discharge will have a great impact on the battery life, a depth of over-discharge may reduce the battery life of 1 to 2 years, and even cause the battery scrapped. Therefore, the rectifier over-discharge protection function is also an important indicator.

Q: Electronic ballasts and electromagnetic ballasts are different: Electronic ballasts can also have more features, such as by increasing the current frequency or current waveform (such as square wave) to improve or eliminate the flashing phenomenon of the fluorescent lamp; can also be through the power inverter process so that the fluorescent lamp can use DC power. Some of the shortcomings of traditional inductive rectifiers make it being replaced by increasingly sophisticated electronic ballasts

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: Is the rectifier pulse the better?: The rectifier is a rectifier, which simply converts AC (AC) into a DC (DC) device. It has two main functions: first, the AC (AC) into DC (DC), the filter after the supply of the load, or supply the inverter; second, to the battery to provide charging voltage. Therefore, it also plays the role of a charger.
