(SMPS) (UPS) General data TA TS m Ambient operating temperature - 20 .. + 80 C Ambient storage temperature - 25 .. + 85 C Mass (-TP version) < 30 (< 36) g Standards EN 50178: 1997 2 pins of O2mm diameter are available on transducer for PCB soldering. Application domain * Industrial Notes : -TP version is equipped with a primary bus bar. 2) Operating at 12V Vc < 15V will reduce measuring range. 3) Derating is needed to avoid excessive core heating at high frequency. 1) Page 1/2 070313/11 LEM reserves the right to carry out modifications on its transducers, in order to improve them, without prior notice. www.lem.com Dimensions HTB 50..400-P and HTB 50..100-TP (in mm. 1 mm = 0.0394 inch) HTB 50..400-P Positive Current Flow 39 14 MAX. 34 d1 6 1.5 19.5 4-0.635x0.635 24.5 5.5 3.5 4321 Secondary Pin Identification 2-d2 Mounting Pins 7 11 3-P=2.5 6 +/-1 9 +/-1 10 19 3 1 2 3 4 +Vc -Vc Output 0V 3 General tolerance: 0.5 mm HTB 50..100-TP 39 14 MAX. 14 MAX. 34 1.5 1.5 17 4-0.635x0.635 4-0.635x0.635 10 3-P=2.5 10.5 3 3 3-P=2.5 6.5 6.5 2 2 3.25 3.25 3.5 3.5 4 321 4 1.5 1.5 3.5 3.5 1.5 1.5 Positive Current Flow Secondary Pin Identification Secondary Pin Identification 1 1 2 2 3 3 4 4 +Vc +Vc -Vc -Vc Output Output 0V 0V 6-1.5x1.5 6-1.5x1.5 14 14 3 3 3 3 11 11 General tolerance: 0.5 mm Page 2/2 070313/11 LEM reserves the right to carry out modifications on its transducers, in order to improve them, without prior notice. www.lem.com |
