Description
The SCS device measures currents and voltages of separate lines (up to 3), connecting
at most three toroids to the appropriate inputs (one toroid, item 3523, supplied as
standard).
The meter processes and saves the following variables:
- instantaneous power in W;
- total accumulated energy in Wh;
The device has an internal memory that can store:
- cumulative energy on an hourly basis for the last 12 months;
- cumulative energy on a daily basis for the past 2 years;
- cumulative energy on a monthly basis for the last 12 years.
In order to allow the device to archive consumption information, the system must be
fitted with a device capable of supplying current date and time information (e.g. Touch
Screen). If this information is not available, the meter will be unable to archive the data,
and will continue calculating the values of the instantaneous variables (power).
The device has a footprint of 1 DIN module and has a housing for 5 configurators: A1, A2,
A3-Ta, A3-Tb, A3-Tc.
