INA219 High Side DC Current Sensor Breakout - 26V 3.2A Max

Model: ina219-FBACA   |    Mpn: 58-1B8R-D1V5   |    Ean: 0720189972614   |    PartNumber: 58-1B8R-D1V5   |   Asin: B00I827TUQ

This breakout board will solve all your power-monitoring problems. Instead of struggling with two multimeters, you can just use the handy INA219B chip on this breakout to both measure both the high side voltage and DC current draw over I2C with 1% precision. Most current-measuring devices such as our current panel meter are only good for low side measuring. That means that unless you want to get a battery involved, you have to stick the measurement resistor between the target ground and true ground. This can cause problems with circuits since electronics tend to not like it when the ground references change and move with varying current draw. This chip is much smarter - it can handle high side current measuring, up to +26VDC, even though it is powered with 3 or 5V. It will also report back that high side voltage, which is great for tracking battery life or solar panels. A precision amplifier measures the voltage across the 0.1 ohm, 1% sense resistor. Since the amplifier maximum input difference is 320mV this means it can measure up to 3.2 Amps. With the internal 12 bit ADC, the resolution at 3.2A range is 0.8mA. With the internal gain set at the minimum of div8, the max current is 400mA and the resolution is 0.1mA. Advanced hackers can remove the 0.1 ohm current sense resistor and replace it with their own to change the range (say a 0.01 ohm to measure up 32 Amps with a resolution of 8mA) We include a 6-pin header (so you can easily attach this sensor to a breadboard) as well as a 3.5mm terminal plug so you can easily attach and detach your load. Usage is simple. Power the sensor itself with 3 to 5VDC and connect the two I2C pins up to your microcontroller. Then connect your target power supply to VIN+ and the load to ground to VIN-. Adafruit has an Arduino library right now that will do all the gain, range and math for you - just plug and go!

Features

  • Requires soldering of header pins (easy!)
  • Measure high side voltage and DC current draw
  • Great for tracking battery life or solar panels
  • Supported by Adafruit Arduino libraries!
  • Perfect for your solar or battery powered Arduino project

Magnelab SCT-0750-150 Split Core Current Transformer (CT) 0.75" ID 0.333V Secondary (Output) 150 Amp Primary (Input)

Model: SCT-0750-150   |    Mpn: SCT-0750-150   |    Ean: 0852659896011   |    PartNumber: SCT-0750-150   |   Asin: B009NVSHBG

Magnelab Split-core transformers are ideal for installation on existing electrical wiring by snapping around the conductor. The Magnelab SCT series have one of the highest industry standards both for interleaving joints and the self-locking mechanism. These current transformers have a rated accuracy of +- 1 percent between 10 and 130 percent of their rated input. The SCT series transformers are UL Recognized, CE, and RoHS compliant. 8 foot twisted pair leads allow for easy ready to go installation.

Features

  • 150 Amp to 0.333 Volt
  • +/- 1% Accuracy at 10% to 130% of rated current
  • Phase angle less than 2 degrees measured at 50% rated current
  • Operates from 50 Hz to 400 Hz
  • UL Recognized, CE, and RoHS Compliant

CR Magnetics CR9550-10-M Current Sensor with Mounting Case, 10 AC, +/-0.5% Accuracy, 50 - 400 Hz Frequency

Model: N/A   |    Mpn: CR9550-10-M   |    PartNumber: CR9550-10-M   |   Asin: B005CWOMPU

The CR9550 Series Current Sensors provides a cost effective method for monitoring electrical current. The sensor generates a 0-5 VDC signal proportional to the input AC current. The output signal is average sensing, calibrated to RMS. The sensor is used with process control and industrial instrumentation equipment. Especially suited for OEM applications that require a low cost solution for numerous monitoring locations. The DC output can be connected directly to an analog input connection without additional signal conditioning. Care must be taken to ensure the burden impedance of the instrumentation is greater than 1.0 megohm. The unit will operate with lower burden impedance but at reduced accuracy. Accuracy: +/-0.5 percent full scale (FS). Ripple: 1 percent Max. Signal out: 0-5 VDC. Max. Signal out: 12 VDC. Frequency: 50 to 400 Hz. Insulation class: 600 V. Operating temperature: -30 degree C to + 60 degree C. Storage temperature: -55 degree C to + 85 degree C. Dielectric withstand: 2500 Vrms. Response time: 250 ms. max. 10-90 percent FS. Calibration: Avg. sensing, RMS calibrated. Output load: 1.0 Megohm or greater for rated accuracy.

Features

  • Applications: OEM current sensing, home automation, monitor motor operation
  • Electrical isolation between circuits, output relay rated up to 20 Amps
  • LED trip status indicator, dead band prevents relay chatter
  • Calibrated dial option available, external current transformers available
  • Applications: monitor electrical heater elements, sense motor over/under loads, detect lamp burn-out, indicate phase loss
  • Variable trip point and time delay, monitors currents from 10 mA to 60 AC amps
