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 Isec value corresponds to a maximum primary current of 15 Amp-turns rms while the Isec value for the ratio of 1:750 corresponds to a max. primary current of 30 Amp-turns rms. 1 VµS = R t x Is x 2F Rt (Ohms): Recommended Terminating Resistance Is (A): Secondary Current F (Hz): Frequency 5) Operating Temperature Range: -40°C to +120°C 6) Pin 2 is on Center-Tapped (CT) versions only 0.60 Ø (0.024) 17.0 (0.669) TALEMA ASXXX 1 2 3 5.0 (0.197) 20.4 (0.803) 17.2 (0.677) 4 .0 (0.157) 6.35 (0.250) 12.7 (0.500) + 4) 9.53 (0.375) 1 + 2 _ 3 _ Primary Sense Current DataSheet4U.com THE TALEMA GROUP • World Wide Toroidal Specialists (07-03) AS Series DataSheet 4 U .com www.DataSheet4U.com AS Series • Current -Sense Inductors & Transformers Electrical Specifications at 25°C Part Number Type 1 AS-200 AS-201 AS-202 AS-210 A.
