Meter Overview
The PM4201 meter is designed for intelligent power monitoring and energy metering requirements. It measures common electrical parameters in three-phase power grids, including three-phase voltage, current, power, power factor, frequency, energy, etc.
The PM4201 meter complies with Class 0.5S accuracy standard. It features high quality, reliable safety and cost-effectiveness, with a compact form factor for easy installation.
Meter Functions
The PM4201 meter supports multiple functions, some of which are listed below:
- LCD display screen: LCD display with intuitive auto-guided navigation via four buttons, showing three lines of parallel values. The display indicator at the top-left corner identifies the parameter being displayed.
- Energy metering
- True power factor measurement
- Active and reactive energy readings
- Timestamped minimum / maximum values of instantaneous parameters
Installation Adapters
When installing the meter in existing panels or cutouts, if the default mounting hardware is not suitable, various installation adapter accessories are available for selection. Installation adapter kits are ordered separately from the meter.
