Meter Function Overview

EasyLogic™ PM4600 series power meters deliver the basic measurement capabilities required for monitoring single-phase or three-phase electrical installations (e.g., current, voltage and energy).

The PM4600 series power meters support multiple functions, some of which are listed below:

LCD display screen:
- Equipped with an LCD dot-matrix display. Parameters can be accessed and operated via four front-panel buttons
- Active, reactive and apparent energy readings
- Power factor measurement (True PF and Displacement PF)
- Timestamped minimum / maximum values of instantaneous parameters
- SOE event logging
- Clock-controlled multi-tariff (up to 4 types) ⁽¹⁾
LED pulse lamp for energy pulse indication
Terminal functions:
- Supports Modbus RTU, DL/T645 protocol communication
- Digital input
- Relay output: configurable for alarm and other functions
- Temperature measurement ⁽¹⁾
- Residual current measurement ⁽¹⁾

⁽¹⁾: Non-standard configuration, available only for selected models, refer to the function summary.
