  1. Parameters Definition And Formula 1) Output Voltage VOUT = VOFF + S × IP VOUT stands for current sensor output voltage at given primary current, VOFF stands for offset voltage, S stands for sensitivity, IP stands for primary current. 2) Accuracy XG = MAX IP ∈ [-IPN, IPN] (VOUT - VREF) - (S × IP) S × IPN × 100% IPN stands for nominal primary current 3) Sensitivity S = VOUT(@ IPN) - VOUT(@ -IPN) 2 × IPN VOUT@ IPN and VOUT@-IPN stand for the current output at IPN and -IPN respectively. 4) Linearity εL = MAX IP ∈ [-IPN, IPN] (VOUT - VREF) - VOE + S × IP S × IPN × 100% S and VOE stand for the average values of the sensitivity and electric offset. 5) Symmetry εSYM = VOUT(@ IPN) - VOFF VOUT(@ -IPN) - VOFF × 100% 6) Hysteresis VOH = MAX ∆H ∆H is the maximum residual output current between full scale positive and negative nominal current. 7) Offset Voltage VOE = VOUT(@ IP = 0) - VREF TMR7559-B Board Mount Precision Current Sensor MultiDimension Technology Co., Ltd. http://www.dowaytech.com/en/

Figure 13. Dimension (unit: mm, tolerances for unmarked scales ±1 mm)

  1. VOUT is positive when the primary current (I P) is in the same direction as the arrow indication on the label
  2. Improper connection may result in permanent damage of the sensor.
  3. Excessive capacitive load may result in distortion of output signals when measuring high frequency primary

signal. Please refer to Output Voltage vs Load Capacitance Curve.

  1. Dynamic performances (di/dt and response time) are best with a single busbar completely filling the primary
  2. Sensor is customizable upon request.
