AC Monitoring
All 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 Hz
- With ranges around 216 V to 253 V
-
USA and Canada which typically is 120 V or 230 V @ 60 Hz
- With ranges around 114 V to 126 V
-
Japan which typically is 100 V @ 50 Hz or 60 Hz
- Eastern Japan is 50 Hz, and Western Japan is 60 Hz
-
World typically is 220V-240 V @ 50 Hz
Where can IPEM SIX be used?
The IPEM SIX board can be used in a number of projects and installations such as:
- Home
- Education
- Offices
- Commercial
- Factories
- Farms
- EV Charging
- Smart Metering
- Greenhouses
- Factories
- Industry
- Solar Farms
- Wind Farms
- Off Grid Systems
Current Monitoring and Interfaces
Expanding the mains current sensors, either CT Clamps, or Rogowski Current Transformers, maybe connected. This allows for IPEM SIX to be used for both lower current Home systems and Industrial or commercial installations, which require higher current monitoring in hundreds of Amps.
Safety First
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 Plus to fully safely function at voltages below 20V.
AC Current Monitoring
AC Mains Current on the IPEM SIX, is safely monitored using an inductive non-direct connection method.
IPEM SIX has selectable inputs to be able to use either:
- CT (Current Transformer) – Home and Office
- This typically is by using a CT (Current Transformer), Current Clamp which can measure up to around 100A. This normally is a split core, such as using the popular YHDC SCT-013 100A-50mA.
- Split core current transformers, or Rogowski – Commercial and Industrial
- For for larger solar farms, commercial and industrial currents, heavy duty split core current transformers, or Rogowski.
- The advantages of Rogowski coils, is that that are flexible air-core sensors, providing a wider, non-saturating range, ease of installation, and excellent high-frequency response.6
