Product Description
Stamford MX321-2 Automatic Voltage Regulator (AVR)
The Stamford MX321-2 is a high-performance, three-phase sensed Automatic Voltage Regulator (AVR) and an integral part of the excitation system for a brushless generator. Powered by a Permanent Magnet Generator (PMG), the MX321-2 provides isolated power to the exciter circuit, ensuring excellent voltage regulation and immunity from non-linear loads. It features advanced functionality including over-voltage protection, short-circuit current limiting, and under-frequency roll-off (UFRO) to safeguard the generator. This genuine Stamford part, model E000-23212, is engineered for reliability and precise control in demanding power generation applications.
Technical Specifications:
- Sensing Input: Voltage 190-264V AC max, 1 or 3 phase, 50/60 Hz nominal
- Power Input (PMG): Voltage 140-220V AC max, 3 phase, 3 wire, 100-120 Hz nominal
- Output: Voltage max 120V DC; Current: 3.7A continuous, 6A intermittent for 10 seconds
- Regulation Accuracy: +/- 0.5% RMS with 4% engine governing
- Features: 3-phase RMS sensing, over-voltage protection, soft start, short circuit current limiting, and under-frequency protection.
