Description

Off Board High Accuracy Current Monitoring Controller

This 6-Channel high-accuracy current monitoring controller makes it easy to get AC current measurements into your favorite IoT cloud platform. This current monitoring controller is available pre-tuned in your choice of 10, 20, 30, 50, 70, and 100-Amp ranges.

Using our IoT interface, plug-in your favorite IoT communication module and develop firmware to read energy anywhere in the world!  The NCD IoT interface support Particle Electron for cellular current monitoring.  Use the Particle Photon to monitor current over WiFi.  The IoT interface also supports Bluz (Bluetooth BLE) or you can use one of our adapters to plug in Arduino Nano, Arduino Micro, USB, PyCom WyPy, directly on-board!  Plug in the SI I2C adapter for interface to Raspberry Pi, BeagleBone, or Arduino Uno.  The NCD IoT interface standard makes it easy to connect to just about any computer or microcontroller!

Based on our plug-and-play I2C interface standard, all NCD IoT devices support I2C communications using a I2C expansion port, making it easy to expand to a wide variety of sensors, relay controllers, PWM controllers, and much more!

This controller handles all of the current calculations for energy monitoring applications.

Use our Particle library to communicate energy monitoring data to the Particle cloud or adapt our library for your specific application using the Arduino wire language.

This device provides an ideal energy monitoring solution for most industrial and commercial applications at a low cost with unmatched accuracy.

This controller includes six off-board current sensors and an I2C cable.

To use this device, simply run an AC power wire through the opening of the current sensor. This controller will read the magnetic field inducted onto the current sensor and provide you with a real-world current measurement value that is 98% accurate (prior to calibration).

This current monitoring controller includes our second generation firmware, which maintains best possible accuracy when measuring inductive loads, minimizing the need for calibration.  This controller is pre-calibrated for resistive loads, but has demonstrated 98% accuracy when measuring most inductive load sources.

Sensors:

This controller includes split-core sensors with 1.5 Meter wires (around 5 feet).  Split-core sensors can be opened and clamped around existing wire, greatly simplifying installation.

I2C Expansion:

This controller includes an I2C expansion port and I2C cable so you can easily expand into other current monitoring controllers, sensors of all types, relay controllers, FET drivers, and much more.

Key Fob Compatibility:

This controller is capable of hosting the PKFR Key Fob receiver for applications that may require a hand-held wireless remote control.

Notes:

For AC Current Measurement Only.  This controller is tuned specifically for the included sensors, and may not be used with any other sensor.  The sensor rating of this controller is 100 Amps; however, this controller is tuned according to your order.  It is not possible to measure current outside the tuned range of this controller.  Never exceed 110% of the rated current range of this controller (10, 20, 30, 50, 70, or 100-Amp depending on variation) or permanent damage to the controller may result.  To achieve highest possible accuracy, each channel may require calibration for the type of load under measurement.  As with all current sensors of this type, loads below 1 Amp (1% of the sensor rating) are known for significantly decreased accuracy (around 90% or less).  To increase accuracy of low-current loads, consider doubling the readings by looping your AC load wire through the sensor a second time.  This will effectively double all readings and provide greater low-end accuracy.

Excessively noisy loads may greatly affect accuracy, but our testing has shown 98% or better accuracy with most loads tested.  This controller dedicates 1.3 seconds for measurement of each channel and cycles through all available channels continuously.  We recommend querying this controller every 10 seconds for best results.

Customize

We Customize Just for You!!

NCD offers many custom IoT electronic design services to help tailor our product to your exact needs.  Whether you are looking for custom firmware, circuit board modifications, metal enclosures, or industrial color printing, we can help you with a wide variety of design services.

Custom IoT Electronic Design Services Process

Most of our users purchase off-the-shelf hardware for initial testing.  Once everything is working, they contact us to build a custom solution which may include specialized changes to the board, firmware, connectors, etc.  Custom boards have many advantages such as reduced wiring, easy installation, small size, less power consumption, and in some cases, an overall reduction in product cost.  Custom IoT Electronic Design Services will have your company name and logo on the board as well as the enclosure.

Customized IoT Electronics

NCD engineers can help build a customized solution for your particular application based on the designs you see on our website.  We can combine devices onto a single board, change the shape, or even some of the components to meet your exact needs.  We also provide turn-key metal enclosures with powder coating and full-color printing on the top side starting at just $500 for setup!  We have more than 20 years of experience in electronics design and manufacturing.  All of our products are designed and manufactured in the USA, so we are here to support the products we make.  We only ask that our customers prototype their needs using our existing products before we customize.

Customization Guidelines

  • Custom designs should be based on our existing product because we can’t build rockets or electric cars over here!
  • We do not provide customization services if it involves the introduction of a new or untested technology.
  • Custom engineering fees depend on your requirements, so please contact us for a quote!
  • We maintain ownership of all designs, including our customized designs as they are based on our existing Design.
  • We will only ship the customized product to you or your authorized agents.
  • We have an NDA available if needed.
  • The turn-around time is about 2-3 weeks.
  • We specialize in low-volume designs, no quantity is too small!
  • We have the ability to scale to large volumes as needed.

Getting Started with Product Customization

All you have to do is contact us and we will walk you through the process from beginning to end, based on your individual needs.  Some people are surprised at how fast we finish CAD design (usually a few hours), but keep in mind, we still have to build your design, which takes considerably more time.  When we customize product, here are the general services we provide:

  • We design the circuit board.
  • We communicate with our customers throughout the customization and manufacturing process.
  • We manufacture surface mount stencils and circuit boards.
  • We program our pick and place machines to build your boards.
  • We build a working sample and run it through our wave solder machine.
  • We test your custom IoT solution.
  • Once the design is finalized it won’t be possible to make changes during production (changes cost money and require us to repeat the above processes)
  • Once it meets all your requirements, we will start production as needed.
  • We work with our metal fabricators to design a metal enclosure if required.
  • You work with our artist to print the top side of the enclosure in full color with your company logo if required.
