Description
Larger 1-phase PMG AVR.
Did you know
- The Stamford AS480 is a half-wave phase-controlled thyristor type Automatic Voltage Regulator (AVR) designed for Stamford brushless generators.
- The AS480 is a standard fit for Stamford P0 and P1 alternator ranges, and is considered a self-excited AVR. It is an upgrade to the SX460 and a compact, lower-cost alternative to the AS440.
- The AS480 is notable for its compatibility with the Excitation Boost System (EBS), which provides additional excitation power during motor starting or short-circuit conditions, allowing the generator to handle heavy loads without stalling. It also utilizes Surface Mount Technology (SMT) for a compact, vibration-resistant, and reliable package.
| Model | Excitation Type | Sensing Input (VAC) | Continuous Excitation Output Current (A) | Voltage Regulation (%) |
|---|---|---|---|---|
| AS480 | Self-excited | 100-264 (1 phase) | 5 | < ± 1.0% |
| AS440 | Self-excited | 100-264 (1 phase) | 4 | ±1.0% |
| MX341 | PMG-excited | 190-264 (2 phase) | 2.7 | ±1.0% |
