The SSR63-12 Retrofit Voltage Regulator is an economical, direct

replacement for existing Basler Electric SSR63-12 voltage regulators

used with brushless synchronous generators. Designed to fit within

the same mounting footprint as the original regulator, the retrofit

solution incorporates a modern AVC63-12 voltage regulator and,

when required, an internal sensing module.

It delivers precise voltage regulation, dependable excitation control,

and fast response times while minimizing installation time and upgrade

costs. Engineered for demanding generator applications, the SSR63-12

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

compensation, cross-current compensation, line drop compensation,

and underfrequency protection.

Compatibility with accessories such as excitation limiters, power factor

controllers, auto synchronizers, and excitation support systems makes

it an ideal modernization  solution for existing generator systems.

Its rugged construction, direct-replacement design, and proven

performance help extend equipment life while improving regulation

accuracy and reliability.

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.
