Description
Legacy Newage AVR, 1980s vintage (service only).
Did you know
- The K125A is an Automatic Voltage Regulator (AVR) associated with Stamford (Newage / Cummins Generator Technologies) alternators. While a specific launch date for the K125A itself is not readily available, Stamford has been producing AVRs for over 100 years, with Cummins Generator Technologies now offering a wide selection of both digital and analogue AVRs.
- The K125A is part of a broad range of analogue and digital AVRs offered by Stamford/AvK, which includes models like the SX460, AS440, AS480, AS540, MX341, MX342, MX321, and MX322. These AVRs vary in specification levels and features, with some like the MX341/MX342-2 being high-end options suitable for demanding applications.
- Stamford AVRs, including the K125A, are designed to ensure consistent voltage output, which is critical for the smooth operation and longevity of power generation systems. They continuously monitor alternator voltage and adjust excitation current to maintain stable levels, offering features like under-frequency, over/under excitation, moisture, and vibration protection.
