MX450
Description
Next-generation PMG AVR with enhanced protections.
Did you know
- The Stamford MX450 Automatic Voltage Regulator (AVR) is a half-wave phase-controlled thyristor type AC regulator. It is part of the excitation system for brushless generators.
- The MX450 is part of Stamford's range of AVRs that are used with alternators excited by a Permanent Magnet Generator (PMG), alongside models like the MX321 and MX341. It is designed for generators with a power output greater than 150kW.
- The MX450 ensures positive voltage build-up from residual levels through efficient semiconductors in its power circuitry. It provides closed-loop control of the output voltage with a load regulation of +/- 1.0%, compensating for load, speed, temperature, and power factor. The MX450 also includes under-speed and sensing loss protection features.
| Model | Sensing Input Voltage (AC) | Output Voltage (DC Max) | Continuous Output Current (DC) | Voltage Regulation |
|---|---|---|---|---|
| MX450 | 190-264V (jumper selectable 120V or 240V) | 90V @ 207VAC input | 4A | < ±1% RMS |
| AS440 | 100-264V (jumper selectable 100-130V or 190-264V) | 82V @ 200VAC input | 4A | ±1.0% |
| SX460 | 95-264V (jumper selectable 95-135V or 190-264V) | 90V @ 207VAC input | 4A | ±1.0% |
