Description
Updated GTA7 revision.
Did you know
- The WEG Grameyer GRT7-TH4E, which is the factory-standard excitation solution for WEG GTA series alternators, is a high-performance analog Automatic Voltage Regulator (AVR).
- The GRT7-TH4E is part of the WEG Grameyer GRT7 series of Automatic Voltage Regulators, which also includes models like the GRT7-TH2.
- The GTA7-2 (likely referring to the GRT7-TH4E as the standard AVR for GTA alternators) is designed for brushless synchronous generators, providing stable voltage regulation even with sudden load changes. Its encapsulated design offers high resistance to vibration and humidity, making it suitable for both land-based and marine applications.
| Model | Continuous Excitation Current (ADC) | Peak Excitation Current (ADC) | Voltage Regulation |
|---|---|---|---|
| GRT7-TH4E (standard for GTA series) | 5.0 | 7.0 (10s) | < ± 0.5% |
| GRT7-TH2 | 35.0 | N/A | N/A |
