Power Meter

The Watford Control Standard Industrial Meter, part of the Rayleigh Instruments RI-F400 easywire series, is designed for DIN 96 panel mounting. It accommodates 330mV input from easywire® CTs (or -/1A and -/5A current transformer input with TAS-SCTEWA module) and is compatible with both single-phase and three-phase networks. The meter features programmable voltage and current transformer ratios, ensuring precise measurements using True RMS technology. Its high-definition white backlit LCD display offers clear visibility in varying lighting conditions. The device is compact, with a panel depth of only 50mm, making it suitable for space-constrained installations. It offers user-friendly operation with simple programming and quick access through quick select push-buttons. Additionally, it provides pulse output and Modbus communication for streamlined data transfer and supports auto or manual page scrolling. The meter also offers the convenience of daisy chaining, allowing connection of up to 32 meters from one supply.
