Meter features

The PM2225C meter supports many features, a few of the features are listed below:

Self guided LCD display and navigation
Energy accounting and balancing
Measurement of both True PF and Displacement PF
Active, reactive, and apparent energy readings
Min/Max values of instantaneous parameters with timestamp.
Cybersecurity: The meter supports the disabling of RS-485 port through front panel keys to prevent unauthorized access. Toggle the RTU devices in case of limited availability of nodes in software system.
Suppression current: This is the minimum current at which the meter starts functioning. The meter can be configured to disregard the measurement of induced / auxiliary load current in the circuit. The suppression current selection can be done through the front display and through communication. The suppression current range is from 5 mA to 99 mA. The meter shows measurement if applied value is above the suppression value. The default suppression current is 5 mA.

You can use the meter as a stand-alone device, but its extensive capabilities are fully realized when used as part of an energy management system.

For applications, feature details and the most current and complete specifications of the PM2225C meters, see the EasyLogic PM2225C technical datasheet at www.se.com
