AN115CSA-1V Application Engineering Kit - AN_115KIT
   Low current - up to 1A RMS
   Bi-directional
   High dielectric isolation

This kit is ideal for evaluating low current and high voltage isolation applications. The sensitivity depends on the number of turns of magnet wire on the bobbin (approx 30mV/amp-turn).

   PCB assembly with CSA-1V-SO
       (PCB size: 12.7mm x 19.0mm x 3.6mm (excluding bobbin))
   Nylon bobbin
   Mating connector
   Extra CSA-1V-SO Sample
   Instruction Sheet - AN_115KIT pdf, 82KB

   Mid current range - 0 to 8A RMS
   Peak current, 50A for < 1 sec
   Bi-directional
   Sensitivity ~ 38 mV/A

This kit is useful in evaluating the sensing of current in traces directly under the IC for mid range currents. Current is limited by the trace width and copper thickness.

Kit includes:
   PCB assembly with CSA-1V-SO
       (PCB size: 12.7mm x 19.0mm x 3.6mm)
   Mating connector

AN118CSA-1V Application Engineering Kit - AN_118KIT
   Mid current range – 0 to 8A RMS
   Peak current – 22A < 1 sec
   Bi-directional
   Sensitivity ~ 110 mV/A

This kit has more sensitivity than the standard AN_120 and is the preferred configuration for this current range if installing a “thru-hole” jumper is an acceptable assembly process.

Kit includes:
   PCB assembly with CSA-1V-SO
       (PCB size: 12.7mm x 19.0mm x 3.6mm)
   Mating connector
   Extra CSA-1V-SO Sample

AN128CSA-1V Application Engineering Kit - AN_128KIT
   Mid current range - 0 to 8 amps RMS
   Peak current – 22A < 1 sec
   High sensitivity ~ 220 mV/A
   Large differential output voltage - ±5 Volts
   High Immunity to stray fields

This kit is useful for evaluating the sensing configuration where high sensitivity and high immunity to stray fields is desired. The output is a differential output and can provide a large voltage swing of ±5 volts for bi-directional current or 0-5 volts for DC currents

Kit includes:
   PCB assembly with CSA-1V-SO
       (PCB size: 12.7mm x 19.0mm x 3.6mm)
   Mating connector
   Extra CSA-1V-SO Sample

This kit is useful for evaluating the sensing of higher currents on the PCB. This kit demonstrates the use of a “mini bus bar” over the top of the IC.

Kit includes:
   PCB assembly with CSA-1V-SO
       (PCB size: 12.7mm x 19.0mm x 3.6mm)
   Mating connector

AN119CSA-1V Application Engineering Kit - AN_119KIT
   External wire current sensing- No limit on current
   Bi-directional
   Sensitivity ~ 60 mV/(d+0.3)A, where d=distance between
    center of wire and top surface of IC in mm.

This kit is ideal for sensing currents in wires. The sensitivity is dependant on the diameter of the wire and thickness of the insulation. Any wire size can be used in this application. Sensitivity can be increased by making a wrap around the sensor.

Kit includes:
   PCB assembly with CSA-1V-SO
       (PCB size: 12.7mm x 19.0mm x 3.6mm)
   Nylon tie wrap

AN121CSA-1V Application Engineering Kit - AN_121KIT
   Very High Current in Bus Bar and Flat conductors
   Bi-directional

This kit is useful in sensing currents in bus bars and flat conductors. Sensitivity depends on the width and thickness of the conductor. Increasing the width and thickness decreases the sensitivity. Currents in the range of 100’s of amps to thousands of amps can be sensed. By installing two kits, one each side of the bus bar and taking the differential output from the two kits, the effect of background fields is reduced.

Kit Includes:
   PCB assembly with CSA-1V-SO
       (PCB size: 12.7mm x 19.0mm x 3.6mm)
   #8-32 Nylon screw
   Mating connector
   Extra CSA-1V-SO Sample
