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.
— Product Features & Benefits
• Installation into the same space previously occupied by a Basler Electric SR
or SSR regulator without additional mounting holes and/or hardware.
• Terminal-to-terminal wiring allows quick field replacement of the original
voltage regulator.
• Integrated CT input burden matching provides compatibility with paralleling
systems utilizing cross-current compensation.
• An accessory input provides compatibility with devices such as var/power
factor controllers or excitation limiters.
• Same reliable operation as the original SR/SSR being replaced.
• Standard retrofit kits easily replace multiple models, including custom models,
of the Basler SR and SSR voltage regulators.
