SA465
Description
Compact AVR for small marine auxiliary sets.
Did you know
- The Stamford SA465 Automatic Voltage Regulator (AVR) was introduced by Newage International Limited, with documentation dating back to at least 2003. It is a half-wave phase-controlled thyristor type AVR, designed using Surface Mount Technology (SMT).
- The SA465 is an analog AVR within the Stamford range. It is considered an earlier model, with the AS440 often serving as a direct replacement and upgrade.
- The SA465 is chosen for its ability to provide closed-loop voltage regulation within +/- 1.5% for brushless generators, compensating for variations in load, speed, temperature, and power factor. It also features under-frequency protection and the capability for parallel running with other similarly equipped generators through a droop CT connection.
| Model | Voltage Regulation | Power Input Voltage (AC) | Output Voltage (DC) | Continuous Output Current (DC) |
|---|---|---|---|---|
| SA465 | +/- 1.5% (with 4% engine governing) | 100-264 V (1 phase) | 85 V @ 207V a.c. | 4A |
| AS440 | +/- 1.0% | 100-264 V (1 phase) | 82 V @ 200 VAC input | 4A |
| MX321 | +/- 0.5% | 170-220 V (3 phase) or 110-120 V (1 phase) (unverified) | Max 120 V (unverified) | 3.7 A (unverified) |
