The Role of High Power Regulated Power Supplies
1, stabilise the voltage: when the grid voltage fluctuations in an instant, high-power regulated power supply will be 10-30ms response speed to compensate for the voltage amplitude, so that it is stable within ± 2 [%].
2, multi-role integrated protection: high-power regulated power supply in addition to the * basic stabilisation of the role of the voltage, it should also have over-voltage protection (more than the output voltage of +10 [%]), under-voltage protection (less than the output voltage of the -10 [%]), phase-loss protection, short-circuit protection overload protection * the basic role of the protection.
3, sharp pulse suppression (optional): the power grid will sometimes be very high amplitude, narrow pulse width of the sharp pulse, it will break through the lower voltage-resistant electronic components. The anti-surge components of the high-power regulated power supply can play a good role in suppressing such sharp pulses.
4, isolation of conductive EMI electromagnetic interference (optional): CNC equipment using AC/DC rectifier + PFC high-frequency power factor correction, itself has a certain degree of interference at the same time on the source of the interference also has strict requirements. High-power regulated power supply filtering components can effectively isolate the grid on the interference of the equipment at the same time can also effectively isolate the equipment on the grid interference.
5, lightning protection (optional): should have the ability to prevent lightning strikes.
The necessity of high-power voltage regulator
With the rapid progress of society, electricity equipment and day by day. However, the aging of power transmission and distribution facilities and the development of lagging, as well as poor design and inadequate power supply and other reasons resulting in the end of the user voltage is too low, while the head of the line users are often high voltage. For power equipment, especially high-tech and precision equipment with strict voltage requirements, it is as if they are not insured.
Unstable voltage will cause fatal injury to the equipment or malfunction, affecting production, resulting in delivery delays, quality instability and other losses. At the same time to accelerate the aging of equipment, affecting the service life or even burn accessories, so that owners face the need for maintenance or short-term need to update the equipment, a waste of resources; serious or even safety accidents, resulting in incalculable losses.
