IPEM SIX is a self-contained, powerful ATM90E32 based, Smart Home and Industry Automation, Real-Time Mains Power Energy Monitor Board, and Kit. No soldering required.
Designed to provide accurate real-time mains monitoring for up up six current inputs, via CT clamps, or Rogowski coils.
The pre-production boards have arrive and successfully completed testing. Production has started for stocking later this month.

A range of the mains current sensors (CT Clamps) maybe connected. This allows for IPEM SIX to be used for both lower current Home systems and Industrial or commercial installation
- The accurate Atmel ATM90E32is used for Enhanced Poly-Phase High-Performance Wide-Span Energy Metering, with fast SPI data communications to an Espressif ESP32-C5 MCU.
- The board can safely monitor a range of mains AC circuits, from Single phase, Split or Dual phase (such as USA), and Three phase 3P3W Delta. Full 50 Hz and 60 Hz.
- An onboard accurate 16bit ADC allows for monitoring of DC voltages up to 80V.
- The RS485 port allows interfacing to other local or remote sensors and monitors.
- A galvanically isolated OPTO output can be used to safely connect or drive a range of external systems or devices.
- Two expansion ports, SPI and I2C, facilitate an optional display panel
- MicroSD card, for buffering or logging data. This is mounted in the display panel.
- The IPEM SIX has been designed to be compact, with an option to fit into a DIN enclosure, for cabinet or rack installations.
As with all our boards, safety is paramount, with AC sensing being from lower voltage inputs, through galvanically isolated mains transformers. Examples are bell transformers. This allows the IPEM SIX to fully safely function at voltages below 20V.
AC MonitoringAll AC Mains is safely and galvanically isolated using a low voltage transformer. Examples are bell transformers.
Supports AC Monitoring Around The World- Europe and UK which typically is 230 V @ 50 HzWith ranges around 216 V to 253 V
- USA and Canada which typically is 120 V or 230 V @ 60 HzWith ranges around 114 V to 126 V
- Japan which typically is 100 V @ 50 Hz or 60 HzEastern Japan is 50 Hz, and Western Japan is 60 Hz
- World typically is 220V-240 V @ 50 Hz
The IPEM SIX board can be used in a number of projects and installations such as:
- Homes
- Education
- Offices
- Commercial
- Factories
- Farms
- EV Charging
- Smart Metering
- Greenhouses
- Factories
- Industry
- Solar Farms
