■ Supply specifications
AC/DC voltage: 90 to 260V (standard) 18 to 60V (on
request). Power consumption:
≤ 30VA/12W (90 to 260V),
≤ 20VA/12W (18 to 60V).
Transformer ratio: up to 6000 (CT up to 30kA).
Up to 6000 (VT up to 600kV).
Filters:
Filter operating range: 0 to 99.9% of the input electrical scale.
Filtering coefficient: 1 to 255
Filter action: display, alarms, serial outputs (fundamental vari-
ables: V, A, W and their derived ones).
Event logging: only with RS232+RTC+Data memory. Type of
data: alarms and max./min. (max. 480 events) stored with date
(dd:mm:yy) and hour (hh:mm:ss) reference and data logger.
Sampling management: only for data logger.
The sample stored within the selected time interval results from
the continuous average of the measured values. The average is
calculated (min. sample) with an interval within two following
measurements of approx. 200 ms. The variables (up to 8) can be
stored as average value, minimum and maximum instantaneous
values. Minimum is intended as lowest value among those sam-
pled in the programmed time interval. Maximum is intended as
highest value among those sampled in the programmed time
interval. See table “the working mode of data logging”.
Data management type: FIFO.
Memory size: 2Mbyte.
Battery life: 10 years.
Data logger function: the data are stored at time intervals from
1 to 60 min.; up to 8 instantaneous variables can be selected.
Historical data storing time. Two different data logger
modes can be selected: average calculation within the pro-
grammed time interval and minimum, maximum values and
average calculation in the programmed time interval.
Data format: day, month; time: hour, minutes, seconds;
type of stored variable: variable value.
