1) L_sec: Secondary inductance tested at 10kHz and 10mV for 1:50 through 1:500

Prim./Sec. ratios and 1kHz/10mV for Prim./Sec. ratio of 1:750

5.0

2) This nominal termination resistance value will yield approximately 1.0V

of output for each amp of current in a single turn sense line. The output

Voltage/Ampere of these devices can be increased or decreased linearly

over a restricted temperature range by adjusting the terminating resistance.

3) For Prim./Sec. Ratios of 1:50 through 1:500, the I_secvalue corresponds to a

maximum primary current of 15 Amp-turns rms while the Isec value for the ratio of
