The PR300's demand measurement function measures average power or current within a specified time limit. It also measures the maximum value during the period of demand measurement. When a specified demand alarm point is exceeded, an alarm is output (open collector). You can set a demand alarm mask time to avoid unwanted alarms near the start of the time limit range.
The PR201 Power Monitors was discontinued on 1/01/2006. The PR300 is a replacement product.
PR300 is a panel-mounted meter designed to meet two user needs: a power facility meter and a meter for monitoring energy consumption.
