High power regulated power supply
A high-power regulated power supply is an electronic device that can provide a stable high-power AC or DC power supply for a load. Including high-power AC regulated power supply and high-power DC regulated power supply
The role of high-power regulated power supply
1. Stable voltage: When there is an instantaneous fluctuation in the power grid voltage, the high-power stabilized power supply will compensate for the voltage amplitude at a response speed of 10-30ms, making it stable within ± 2 [%].
2. Multi function comprehensive protection: In addition to the most basic stable voltage function, high-power regulated power supplies should also have overvoltage protection (over+10% of output voltage), undervoltage protection (below -10% of output voltage), phase loss protection, and short-circuit overload protection.
3. Sharp pulse suppression (optional): Sometimes, the power grid may experience sharp pulses with high amplitude and narrow pulse width, which can puncture electronic components with low voltage resistance. The anti surge components of high-power regulated power supplies can effectively suppress such sharp pulses.
4. Isolation of conductive EMI electromagnetic interference (optional): CNC equipment often uses AC/DC rectification+PFC high-frequency power factor correction, which has certain interference and strict requirements for interference sources. The filtering components of high-power regulated power supply can effectively isolate the interference of the power grid on equipment, and also effectively isolate the interference of equipment on the power grid.
5. Lightning protection (optional): It should have the ability to prevent lightning strikes.
The necessity of high-power regulated power supply
With the rapid progress of society, the number of electrical equipment is increasing day by day. However, the aging and lagging development of power transmission and distribution facilities, as well as insufficient design and power supply, have caused low voltage for end users, while line users often have high voltage. For electrical equipment, especially high-tech and precision equipment with strict voltage requirements, it is like not being insured.
Unstable voltage can cause fatal injury or malfunction to equipment, affect production, and cause various losses such as delayed delivery time and unstable quality. At the same time, it accelerates the aging of equipment, affects its service life, and even burns out accessories, causing owners to face the problem of needing maintenance or the need to update equipment in the short term, wasting resources; In severe cases, accidents may even occur, causing incalculable losses.
