Volt Meter

The Watford Control Standard Light Meter, part of the Rayleigh Instruments RI-F220 Series, is designed for DIN 72 panel mounting. It supports -/1A or -/5A current transformer input and is compatible with both single-phase and three-phase networks, adaptable to balanced or unbalanced load systems. The meter allows for programmable voltage and current transformer ratios, ensuring precise measurements using True RMS technology. Its high-definition white backlit LCD display offers clear visibility in all lighting conditions. The device is user-friendly, featuring simple programming and operation with quick select push-buttons for efficient navigation. Additionally, it provides pulse output and Modbus communication (Mbus available) for streamlined data transfer. The meter is available in two versions: one with a single pulse output and the other with a single pulse output and RS485 Modbus communication. Housed in a compact DIN 72 case, it's suitable for easy panel mounting.
