The SR6A Retrofit Voltage Regulator is an economical, direct replacement

for existing Basler Electric SR6A voltage regulators used in 400 Hz

generator applications. Designed to fit within the same mounting footprint

as the original regulator, it provides accurate voltage regulation, fast

response times, and dependable excitation control for brush and brushless

synchronous generators. The retrofit package incorporates a modern AVC63

-12 voltage regulator and, when required, an internal sensing module, making

upgrades straightforward and cost-effective.

Built for reliable performance in demanding power generation environments,

the SR6A Retrofit supports single- or three-phase sensing, reactive droop

compensation, line drop compensation, underfrequency protection, and

accessory integration. Its rugged construction, compatibility with existing

systems, and easy installation make it an ideal solution for extending the

service life of legacy generator voltage regulation systems while improving 

performance and maintainability.

The SR and SSR Retrofit Voltage Regulators are designed as economical,

direct replacement solutions for legacy Basler SR and SSR voltage regulators.

Engineered for quick installation, these retrofit kits fit into the existing

mounting space and utilize terminal-to-terminal wiring to simplify field

replacement. Integrated CT input burden matching supports paralleling

systems with cross-current compensation, while accessory inputs provide

compatibility with var/power factor controllers and excitation limiters.

The SR and SSR Retrofit series delivers the same dependable performance

as the original regulators while helping extend the life and reliability of

generator excitation systems.
