HOW TO ORDER SR 1- 04 60 F Z M FEATURES Packaging Resistance Tolerance F = ±1% Current shunt resistors are low resistance precision resistors used to measure AC or DC electrical currents by the voltage drop those currents create across the resistance. Sometimes called an ammeter shunt, it is a type of current sensor. 2 or 4 ports available Tight Tolerance of ±1% and Tight TCR of ±100ppm Rated Voltage 60mV = 60 100mV = 100 APPLICATIONS TCR (ppm/°C) Z = ±100ppm Rated Current 100A = 01 400A = 04 200A = 02 600A = 06 300A = 03 1000A = 10 1200A = 12 1500A = 15 2000A = 20 Body Style (refer to schematic table) 1, 2, or 3 Current Shunt Resistor Series Current Measurement of AC or DC electrical currents RV battery monitor and battery chargers Marine battery monitor and battery chargers Golf Cart, Wheelchair, Electric Bike batteries & chargers Digital panel meter Ammeter Solar Power, Wind Power generators batteries & chargers Electroplating and metal plating Amp Hour measurement Hand Radio & Amateur Radio base station equipment, battery monitoring and chargers ELECTRICAL CHARACTERISTICS Item SR1-03 Rated Current 300A 60/100mV Rated Output 0.20/0.333 Ω Milliohm Heat Resistance Weight (Kg) Tolerance TCR (ppm/°C) Operating & Storage Temp SR1-04 400A 60/100mV 0.15/0.25 - SR1-06 600A 60/100mV 0.10/0.167 - SR1-10 1,000A 60/100mV 0.06/0.10 - SR2-12 1,200A 60/100mV 0.05/0.083 - SR2-15 1,500A 60/100mV 0.04/0.067 - SR2-20 2,000A 60/100mV 0.03/0.05 - SR3-01 100A 60/100mV 0.60/1.00 1.5 0.24 SR3-04 400A 60/100mV 0.30/0.50 0.55 0.24 SR3-06 600A 6/1000mV 0.15/0.25 0.42 0.24 SR3-10 1000A 60/100mV 0.06/0.10 0.23 0.56 ±1% ±100 -55°C ~ +125°C SCHEMATIC SR1 SR2 SR3 Construction Materials Terminal: Cu plated Ni Resistance: Manganin Junction: Weld DIMENSIONS (±0.2 mm) Series SR1-03 SR1-04 SR1-06 SR1-10 SR2-12 SR2-15 SR2-20 SR3-01 SR3-04 SR3-06 SR3-10 A 155 155 175 175 185 185 215 100 100 100 100 American Accurate Components, Inc.
