Description
Top-end digital AVR for large LSA machines.
Did you know
- The Leroy-Somer R734 module was introduced as an optional three-phase sensing module designed for use with single-phase sensing voltage regulators like the R438, R448, R449, and R452. It appears in documentation from at least 2003.
- The R734 is an accessory module that enhances the capabilities of certain Leroy-Somer Automatic Voltage Regulators (AVRs), rather than being a standalone AVR itself. It offers more advanced functionality compared to the R731 module, specifically in handling unbalanced loads.
- The R734 module is particularly chosen for its ability to enable parallel operation with highly unbalanced loads, which are primarily single-phase loads connected line to neutral.
| Model | Sensing Type | Parallel Operation | Unbalanced Load Capability |
|---|---|---|---|
| R734 | 3-phase current and voltage sensing | Yes | Yes (unbalance > 15%) |
| R731 | 3-phase voltage sensing | Yes | No (compatible with balanced installations only) |
| R726 | Not specified (4-function regulation system) | Yes (PF regulation, voltage equalization, coupling to mains) | Not specified |
