Nooyi DC Power Supply is being tested....
This high-frequency isolated DC power supply adopts ARM's new type 32-bit processor as the monitoring chip, adopts PWM pulse width modulation mode, IGBT as the main control component, medium and high frequency transformer isolation, fast recovery diode rectification, high efficiency DC constant voltage constant current andconstant power supply. The working mode is from the AC-DC-medium-high frequency AC-DC process, which is small in size, energy-saving and high in efficiency. It is a new generation of high-frequency isolated DC power supply and is an alternative to SCR thyristor high-frequency isolated DC power supply product. #power #energy #mode#Nooyi
ZBW Non-Contact Voltage Regulator
Under what circumstances should use voltage regulator? Why use a voltage regulator?
Unstable voltage will cause fatal injury to production or testing equipment, affecting production, resulting in delivery delays, unstable product quality and other losses. At the same time, accelerate the aging of equipment, affect the service life and even burn accessories, so that the owners are faced with the trouble of needing maintenance or need to update equipment in a short time, waste of resources, and even safety accidents, causing inestimable losses. Therefore, it is necessary to use the voltage regulator, voltage regulator for your equipment escort. What is the reason for using a voltage regulator?So, why does industry need to use the voltage regulator? Voltage regulator is mainly to respond to voltage changes, its main classification has its following several categories. According to tests by power experts, there are several kinds of problems that often occur in the power grid and cause interference or damage to computers and precision instruments:
1ใSurge: output voltage effective value is higher than 110% of the rated value and lasts for one or more cycles. Power surges are mainly caused by high voltage in the grid due to sudden uninstallation when large electrical equipment connected to the grid is shut down.
2ใHigh voltage tip pulse: voltage with a peak value of 6000V and a duration from 1/10,000th of a second to 1/2 cycle (10ms). This is mainly due to lightning strike, arc discharge, static discharge or switch operation of large electrical equipment.
3ใTransient overvoltage: pulse voltage with a peak voltage up to 20,000 V but with a duration of between one millionth and one millionth of a second. Its main cause and possible damage are similar to high-voltage spike pulses, but the solution will be different.
4ใVoltage sag: refers to the state of low voltage when the effective value of the mains voltage is between 80% and 85% of the rated value and lasts
