The SA series are conventional inlet filters with C14 sockets It can be conveniently installed and put into use, an optimal choice in cost reduction for you.
The FA series are a kind of DC feed-through filter (single C-type), with primary capacitance of 105, used for suppression of noises in mid-high frequency.
For PD series, the common mode noise suppression capability is strengthened The multi-level common mode filtering circuit is used, effectively.suppressing the common mode noises
