Core Technical Capabilities
The 126mm width casing mounts directly onto 35mm DIN rails, fitting standard commercial distribution boards to optimize panel space.
Tracks active/reactive energy and real-time parameters like voltage, current, active power, and power factor for precise sub-metering.
Accommodates up to 100A direct connection through heavy-duty copper terminals engineered to limit temperature rise under continuous maximum load.
Features RS485 Modbus-RTU communication for reliable integration into energy management systems, PLCs, and SCADA networks.
Secures historical consumption data and system parameters automatically in internal non-volatile memory during unannounced power outages without relying on battery backup.
Includes a backlit LCD screen that cycles through phase metrics for fast, error-free physical inspections by maintenance teams.
Wiring Diagram & Terminal Configuration
3-Phase 4-Wire (3P4W): Standard setup for typical commercial and industrial grids with neutral lines, supporting both direct connection (up to 100A) and CT-operated connection (1.5A).
3-Phase 3-Wire (3P3W): Available upon request for specific delta-connected industrial networks without a neutral line, supporting both direct and CT-operated configurations.
Field Note: A permanent, high-contrast wiring schematic is laser-etched directly onto the side of the meter casing to prevent installation errors during field commissioning.
OEM/ODM & Customization Services
To support your local market branding and regulatory compliance, we provide flexible manufacturing options:
Laser Marking: Complementary custom branding, including your logo, model numbers, and specific wiring diagrams laser-etched onto the meter casing.
Firmware Customization: Modification of Modbus register addresses and communication protocols to match your existing EMS or third-party software platforms.
