Tailored solutions for diverse sectors and challenges.
The SR4A Retrofit Voltage Regulator is an economical, direct replacement for existing Basler Electric SR4A voltage regulators. Designed for brush and brushless synchronous generators, it delivers accurate voltage regulation, dependable excitation control, and fast response times while fitting within the same mounting footprint as the original regulator. The retrofit package incorporates a modern AVC63-12 voltage regulator and, where required, an internal sensing module, making installation quick and straightforward.
Engineered for reliable operation in demanding power generation environments, the SR4A Retrofit supports single- or three-phase sensing, reactive droop compensation, line drop compensation, underfrequency protection, and integration with power factor controllers, excitation limiters, and auto synchronizers. Its rugged construction, ease of installation, and compatibility with existing generator systems make it an ideal solution for extending equipment life and improving voltage regulation performance.
