Active power filters are integral parts of nearly all power electronic systems whereby accurate power quality design features such as harmonic cancellation and reactive power balance ability. These filters do not wait until circuit opens and then restores the power supply but rather respond instantly with the supply uninterrupted to ensure the electrical systems are in good working condition. By deploying these active power filter technologies, companies can severe energy losses reduce improve systems and preserve the energy quality requirements coupling. Sinotech Group stands for such commitment to values of quality and also innovation which is why we are successfully numerous cutting edge solutions to global power customers.
