Description
Legacy Newage PCB AVR (service only).
Did you know
- The Marelli M40FA640A, also known as the MARK I, was introduced around September 2011. It is designed for synchronous generators within the Marelli Motori MJB series alternators.
- While often cross-referenced with Stamford (Newage / Cummins Gen Tech) models due to market overlap, the M40FA640A is primarily a Marelli Motori product. Within the broader AVR market, it is suitable for generators ranging from 10 to 2000 kVA.
- The M40FA640A is known for its robust design, featuring full insulation to ensure high reliability in challenging environmental conditions such as high humidity, dust, salt atmosphere, and significant vibration levels. It is also versatile, capable of operating in both single and three-phase applications.
| Model | Regulation Accuracy | Output Current (DC, continuous) | Voltage Sensing |
|---|---|---|---|
| M40FA640A | ±0.5% | 8A | 170-270V / 380-415V / 440-480V (Three or Single Phase) |
| Stamford MX321 | Highly advanced (specific accuracy not detailed, but noted for absolute voltage regulation) | Not specified (intermittent 6A for 10 secs mentioned for MX341, but not MX321) | 3 phase sensing |
| Stamford MX341 | Not specified | 3.5A (continuous), 6A (intermittent for 10 secs) | Single phase sensing |
| Stamford AS440 | ±1.0% | Not specified | Single phase sensing |
