Switching Power Supply - Preen AFV-P Series
Series AFV-P of Preen has upto 9 times inrush capability
Preen’s AFV-P series, high performance programmable AC power source, provides standard inrush current capability up to 4.5 times of output rated current (Irms) and optional 9 times inrush capability, which makes the AFV-P series the industry-leading AC source that delivers the highest peak current with the smallest output power. It is an ideal AC power source for high inrush current drawn by the switching power supplies and helps users to effectively save the cost and space. Moreover, the users can set the start and end angle with the AFV-P series to simulate the maximum peak current (Ipeak) at the initial power-on stage to ensure product reliability at different input conditions.
Using AFV-P-1250 model as an example, the graph below is the turn-on waveform of a switching power supply with start angle at 90 degrees.
