FAQs
PXE2MB1A4 is designed to work exclusively with PXE Rogowski Coil CTs, simplifying current measurement without door changes to primary transformers. This integration reduces wiring complexity, improves measurement fidelity at conductors with tight clearances, and speeds commissioning in switchgear assemblies and motor control centers.
ANSI C12.20 Class 0.1 indicates high accuracy in metering across a wide dynamic range, supporting precise energy billing, demand calculations, and regulatory reporting. In practice, expect minimal error percent under typical load profiles, which translates to more reliable energy dashboards and ROI calculations.
The meter supports 400Vac L‑N and 690Vac L‑L, with a frequency rating of 50/60 Hz. This makes it suitable for most industrial environments, including facilities with mixed voltage feeders or future expansion plans, while maintaining accurate measurements across standard power systems.
The device includes a built‑in RS485 port with Modbus‑RTU and DNP3.0 support, enabling straightforward data exchange with SCADA, EMS, and monitoring software. Configuration is typically handled via field wiring and simple parameter setup, allowing rapid data integration and centralized energy analytics.
Consider mounting space, RS485 wiring, and the need for Rogowski CTs in your design. The meter’s compact size and simple wiring reduce panel real estate and installation time, while high‑fidelity data supports energy optimization programs, helping justify the purchase through measurable energy savings and improved regulatory compliance.
