Description
Next-generation digital AVR.
Did you know
- The Leroy-Somer R731 is a three-phase sensing module designed to enhance the voltage monitoring capabilities of existing Leroy-Somer Automatic Voltage Regulators (AVRs).
- The R731 acts as an accessory module, transforming single or dual-phase monitoring AVRs, such as the R250, R438, R448, R449, and R450, into comprehensive three-phase monitoring solutions.
- Its primary strength lies in providing complete three-phase voltage monitoring, which is crucial for industrial applications, commercial facilities, and critical power systems where balanced three-phase power delivery is essential.
| Model | Function | Voltage Sensing | Compatible AVRs |
|---|---|---|---|
| R731 | Three-phase sensing module | Three-phase | R250, R438, R448, R449, R450, R450F |
| R450 | Automatic Voltage Regulator | Single-phase (can be three-phase with R731) | Standalone |
| R180 | Automatic Voltage Regulator | Single-phase | Standalone |
| R150 | Automatic Voltage Regulator | Single-phase | Standalone |
