※1 Difference between maximum primary current and linear sensing range
Maximum primary current indicates the current value which can be applied for a long time in a current sensor and depends on the cross-sectional area of the primary conductor. Current sensors can be damaged when they have been used for a long time over the maximum effective current value. If current flows at a short period within msec order, such as an over current, current sensors are not damaged.
Linear sensing range is the current range where linear output of the current sensor is guaranteed. Output will be saturated when the current value exceeds the linear sensing range, and will return to a normal operation when the current value returns within the linear sensing range.
