## Summary description

ZAMEL MEW-01/LITE is a three-phase electrical energy monitor designed to measure and monitor consumption across three phases. It provides real-time energy monitoring for residential and small commercial installations, enabling tracking of power usage, detection of imbalances and support for energy management. Suitable for mounting in electrical panels where phase-by-phase monitoring is required.

## Long description

ZAMEL MEW-01/LITE is a three-phase energy monitor designed for installation in distribution boards to measure and display electrical energy consumption on all three phases. The device provides continuous real-time monitoring of active power and cumulative energy, enabling detection of phase imbalance and helping to track consumption patterns in residential and small commercial installations. The meter is suitable where phase-by-phase monitoring and basic energy management are required.
Advantages
The ZAMEL MEW-01/LITE delivers straightforward three-phase measurement with clear output for each phase and total values, allowing quick identification of uneven loads. It supports continuous monitoring without complex configuration, which simplifies installation and day-to-day operation. The device's compact form factor enables mounting in standard electrical panels while providing accurate tracking of energy consumption for load analysis and simple energy management tasks.
Suitable for
 Monitoring household three-phase electricity consumption
 Small commercial premises requiring phase-by-phase energy tracking
 Detecting phase imbalance and uneven loading of circuits
 Integration into basic energy management routines and consumption logging
Key specifications
 Measurement type: three-phase active power and cumulative energy
 Installation: DIN-rail or panel mounting suitable for distribution boards
 Display: phase and total readings for power and energy (digital display)
 Input: compatible with standard low-voltage three-phase supply
 Application: residential and small commercial electrical installations
How to use
Install the energy monitor in the electrical panel according to the wiring diagram provided by the manufacturer, connecting each phase to its corresponding input. After powering the device, verify that the display shows phase and total energy readings and confirm correct phase order and presence. Use the monitor to read real-time power and cumulative energy values; consult the product manual for details on display navigation and measurement units. Regularly check readings to spot deviations or imbalances that may indicate faults or inefficient loads.
Usage recommendations
Place the monitor in the main distribution board close to the incoming supply for accurate phase-by-phase readings. Verify correct wiring and secure connections during installation, and compare measurements periodically with utility billing or other meters to validate accuracy. For troubleshooting phase imbalance, inspect connected circuits and redistribute loads where practical.
