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

Model: 29439   |    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

Loulensy AC Current Transducer Sensor Transformer 0-10A 20A 50A User-selectable Input with 4-20mA DC Output

 PartNumber: FCS521-SD-420E   |   Asin: B00KJ6IX04

Application FCS series current transducer combines a solid-core current transformer and signal conditioner with top-mounted terminals, and is suitable for use in industrial automation systems. The transducer provides average root-mean-square (RMS) measurement for sinusoidal alternating current waveforms, with an accuracy of 1.0% full scale (FS) and a response time of 100 ms for voltage output models and 300 ms for current output models (10-90% step change). User-selectable input current ranges reduce inventory needed. This current transducer is Underwriters Laboratories (UL) listed and Conformit Europ enne (CE) certified for quality assurance. It is suitable for monitoring linear, constant-speed alternating current (AC) loads that produce sinusoidal waveforms. Current transducers are used to detect electrical current flowing in a wire or cable, and to generate an electrical signal proportional to the current for measurement or control. The transducer consists of an electrical winding, a magnetic core, and a signal conditioner. When current flows through a wire, the transducer winding generates a current, which produces a magnetic field in the core, which then creates a proportional current or voltage output signal. Current transducers are used in industrial automation systems for monitoring, alarming, and equipment control. Warranty & Return 1.24 MONTHS QUALITY guarantee. Warranty : In the process of Exchanging products Buyer shoud bear freight of return shipping, while Manufactuer should bear freight of sending. 2.Buyer can return products and get FULL REFUND of item value within 30 days after receiving , if there's any quality problem in original products; Freight of return should be beard by manufacturer.

Introduction
This is a breakout board for the fully integrated Hall Effect based linear ACS758 current sensor. The sensor gives precise current measurement for both AC and DC signals.The thickness of the copper conductor allows survival of the device at high overcurrent conditions.
The ACS758 outputs an analog voltage output signal that varies linearly with sensed current.
This current sensor enables you to monitor currents in your project every second for energy saving or circuit protecting purposes.

Features
- Arduino interface compatible
- 120 kHz typical bandwidth
- 3 s output rise time in response to step input current
- Output voltage proportional to AC or DC currents
- Factory-trimmed for accuracy
- Extremely stable output offset voltage
- Nearly zero magnetic hysteresis
- Total output error improvement through gain and offset trim over temperature
- Monolithic Hall IC for high reliability
- Ultra-low power loss: 100 internal conductor resistance

Specifications
-Operating Voltage(analog): 5V
-Peak Measuring Voltage:3000V(AC),500V(DC)
-Current Measuring Rang:-50~50A
-Sensitivity:40 mV/A
-Operating Temperature: -40~150 C
-Dimension:34x34mm

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

  • 0.333 Volt AC output at rated input current of 100 Amps with 0.750 inch ID
  • +/- 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
