Called ‘IPEC’, it provides three phase (3P3W, Y or Δ), split-phase, or three-channel single phase monitoring, and has an expansion ports that can be configured for DAC, PWM, MPPT (peak power tracking) or I2C outputs.
100A/50mA
“The board may be used as a stand-alone controller-monitor, integrated within an in-house network, or with an MQTT IoT cloud,” according to the company. “It has applications including smart battery charging, resistive power control such as immersion heaters, and solar power diverters.”
Possible output parameters include: active, reactive, import and export powers, pwer factors, line current and voltage.
Measuring 70 x 53mm, it is built around two microcontrollers: an Espressif ESP32-WROOM MCU and Microchip ATM90E32.
There are two versions, one with a built-in Wi-Fi and Bluetooth antenna, and one with an U.FL connector for an external connector.
12Vac power is needed for the board and it has six main inputs for three current transformers and three voltages.
“Safety is a primary focus for all our boards, so only low-voltage SELV ac is used, providing galvanic isolation,” said Ditronix.
When developing code, it can be powered via its MicroUSB input.
A PlatformIO (VS Code) firmware application is available for testing the boards and for use as a basis for further code development. “Firmware for the board can also be developed in the Arduino IDE, if preferred. Example code is provided on GitHub,” said the company.
Accessories include a 0.96in OLED display, an external 2.4GHz antenna, 100A/50mA current transformer and a 12Vac transformer.
An ADC/PWM expansion board (IPEX) is due for release in the third quarter.
Ditronix is based in Sussex UK, where it designs and manufactures its products.
