The image on the left shows the display from one of SACI’s maximum demand ammeters. These units measure the maximum average load over a 15-min period (or 8 min period on demand) which is achieved thanks to the inherent time lag in the bimetallic movement.

Some units also include a reading of the instantaneous load by including a standard ammeter.

An alarm is included in the units BEC2VA, BEC3VA and BEC4VA with a red LED indicator and which can be adjusted from the front of the unit.
