The offset ripple can be reduced by an external low pass. Simplest solution is a passive low pass filter of 1st order with f g 1 = 2π ⋅ R M ⋅C a In this case the response time is enlarged. It is calculated from: t′ ≤ t + 2, 5R r r M C a Applicable documents Current direction: A positive output current appears at point I S, by primary current in direction of the arrow. Constructed and manufactored and tested in accordance with EN 61800. Housing and bobbin material UL-listed: Flammability class 94V-0.

Response time (describe the dynamic performance for the specified measurement range), measured as delay time at I P = 0,9 . I Pmax between a rectangular current and the output current. Delay time (describe the dynamic performance for the rapid current pulse rate e.g short circuit current) measured between I Pmax and the output current i a with a primary current rise of di 1/dt = 100 A/µs.
