The “safety horse” for voltage sags in enterprises – DySC dynamic voltage sag compensator
Do you know what is a voltage sag? With the parallel connection of the power grid, the increasing expansion of the ring network, and the increase in distribution circuits brought about by the increase in the capacity of the feed transformer, the phenomenon of voltage sags (shocking) is becoming more and more frequent, mainly manifested as temporary voltage fluctuations in factories or equipment. dips, dips and short interruptions. The reason is that in addition to the increased probability of voltage fluctuations caused by adjacent circuit faults, natural disasters, accidents, human factors, etc. may also cause a short-term drop in the incoming grid voltage. This drop may be single-phase or three-phase. of.
According to a study by the Electric Power Research Institute (EPRI), Industrial electricity customers experience an average of 66 voltage dips per year. For enterprises, voltage sag is not only one of the major problems affecting the normal operation and safe production of electrical equipment, but also brings cost expenditure, production reduction and defective products to enterprises, including manpower, equipment, property, and output as waste products. An important factor in losses such as profits. It can be seen that the voltage sag has caused a huge obstacle to the improvement of production efficiency in the manufacturing industry. So how can manufacturers flexibly address this power quality challenge?

DySC Dynamic Voltage Sag Compensator
The DySC dynamic voltage sag compensator (abbreviated herein: DySC) from Rockwell automation is a unique and innovative industrial-grade voltage sag solution on the market today. It adopts the patented inverter technology and has perfect power protection function, which can solve the problem of voltage sag and temporary power interruption faced in the key manufacturing process, and is an ideal solution for the need of voltage sag protection. What’s more, the solution has no batteries and no moving mechanical parts, requiring little maintenance and correspondingly increasing production reliability.
For DySC users, because the system does not contain batteries, there is no need to consider battery maintenance and environmental pollution, which greatly shortens and reduces maintenance costs and maintenance time, and due to ultra-low power consumption, it has also become a total owner Very low cost voltage sag protection system.
It is worth mentioning that the power range of DySC series is very wide, including products from single-phase 250VA to three-phase 2MVA, which can protect a single component, a single machine, or the entire switchboard.
How does DySC help the manufacturing industry with high-quality power supply?
In practical applications, DySC can monitor the voltage situation in the factory in real time, draw extra current from the power supply through the high-speed IGBT inverter, and compensate for the lack of voltage during voltage sags. In the event of a temporary power outage, the DySC will use a portion of the energy stored in the rectifier and inverter capacitors to supply the load with 100% voltage.
The solution process of DySC is specifically that when the system is in normal motion, the current flows through the static switch to supply power to the load, and the power module is in the disconnected state. However, once a voltage sag occurs, the DySC controller will turn off the static switch, so that the current path will switch from the static switch to the power module connected in series with the power supply and load within 2ms to complete the compensation. After the voltage sag passes, the power module is disconnected, and the power supply supplies power to the load through the static switch again. This series of simple operations endows infinite possibilities to the manufacturing industry.
Nine Advantages of DySC for Power
