ASM Series • Current Sensor for 50/60 Hz ASM Series current sensors operate as the sealed secondary of a current transformer while the conductor carrying the current to be measured functions as a one turn primary. Measurement accuracy can be improved by increasing the number of primary turns. Applications include detection of branch circuit overload and load drop or shutdown. Features • Fully encapsulated for optimal PC board mtg. • Mains frequency of 50/60 Hz • Primary current ratings from 1 to 100 Amps • Primary to secondary isolated to 2500 VAC • Operating temperature range: -40° C to +120°C • Competitive pricing due to high volume production • Manufactured in an ISO-9001:2000, TS-16949:2002 and ISO-14001:2004 certified Talema facility • Fully RoHS compliant ASM-010 Current R an g e Output Voltage Tolerance ASM-010 ASM-020 ASM-030 ASM-050 ASM-075 ASM-100 1 - 10 Amps 1 - 20 Amps 1 - 30 Amps 5 - 50Amps 5 - 75 Amps 5 - 100 Amps ±10% ±10% ±10% ±10% ±10% ±10% Typical Response 17.0 (0.669) 3 0.60 Ø (0.024) ASM-020 40 20.4 (0.803) TALEMA ASM-010 1 9.53 (0.375) ASM-010 Ø 5.0 (0.197) 4 .0 (0.157) 12.7 (0.500) 1 35 Output Voltage (mV) Part Number 3 30 25 20 15 10 5 17.20 (0.677) Ø 5.0 (0.197) 0 1 2 4 6 8 10 12 Current (Amps) 25.0 (0.984) ASM-010 & ASM-020 ASM-020 80 E 20.0 (0.787) 1 15.5 (0.610) 70 3.5 (0.138) Output Voltage (mV) 0.60x0.88 mm (0.024x0.035) 4 12.5 5 (0.492) 8 Output Voltage (mV) 50 ohms 23.0 (0.906) Note: Pins #1 and 8 are Blank 60 50 40 30 20 10 0 ASM-030 1 2 4 6 8 10 12 14 16 18 20 22 24 Current (Amps) Ø 9.27 (0.365) ASM-030 80 E 25.4 (1.00) 0.80 Ø (0.031) 5.0 (0.197) 1 3 1 2 3 2 15.24 (0.600) 11.18 (0.440) 70 Output Voltage (mV) TALEMA ASM-030 220 ohms 7.62 (0.301) Output Voltage (mV) 3 1 2 25.15 (0.99) 60 50 40 30 20 10 0 1.78 (0.070) 1 5 ASM-050, ASM-075 & ASM-100 25 30 35 40 8 E 0.75 x 1.10 mm (0.030 x 0.043) 7.50 (0.295) 3 4 1 2 20.5 (0.807) 1 2 220 ohms Output Voltage (mV) Output Voltage (mV) 135 27.5 (1.085) 35.0 (1.378) 20 ASM-050, ASM-075 & ASM-100 17.5 (0.689) 3.5 (0.138) 7 32.0 (1.260) 15 Current (Amps) Note: Pin #3 is Blank Ø 8.0 (0.315) 10 120 105 90 75 60 45 30 15 0 5 20 40 60 80 100 Current (Amps) Germany: Int.+49 89 - 841 00-0 • Ireland: Int.+35 374 - 954 8666 • Czech Rep: Int.+420 377 - 338 351 • India: Int.+91 427 - 244 1325 http://www.talema-nuvotem.com (06-06) ASM Series
