FTS series inverter with MPPT solar hybrid
What is conducted interference?
Answer: Conducted interference is a concept used to measure the magnitude of electronic interference signals sent by electronic products to the entire power grid during operation. All electronic products will send out interference signals to the power grid when using electricity. If the interference signal is too large, it will affect the power quality of the entire power grid, thereby interfering with the normal operation of other electrical appliances. Therefore, most countries have a rigid regulation on the conducted interference index of electronic products, prohibiting the production and sale of products with excessive conducted interference.
What are the most important items in the power test?
Answer: Mainly include cross load, surge, input voltage, ripple noise, output short circuit, over power, conversion efficiency, power factor, response time, timing, noise, conducted radiation, leakage current, high and low temperature test, etc.
What is inrush current?
Answer: Inrush current refers to the peak current flowing into the power supply equipment at the moment when the power is turned on. This peak current is much greater than the steady-state input current because the input filter capacitor charges rapidly. The power supply should limit the surge level that AC switches, bridge rectifiers, fuses, and EMI filter components can withstand. Repeatedly switching the loop, the AC input voltage should not damage the power supply or cause the fuse to blow.
