Basler 9507900205 SSR Retrofit Static Voltage Regulator

The Basler 9507900205 is a static voltage regulator retrofit kit designed to replace obsolete analog regulators in brushless synchronous generators. This kit includes the SSR (Static Voltage Regulator) unit and necessary mounting hardware, providing a modern, solid‑state replacement that enhances voltage regulation accuracy and reliability. It is particularly useful for upgrading aging generator sets in industrial, agricultural, and standby power applications.

The SSR unit offers precise voltage regulation with built‑in over‑excitation and V/Hz protection. It features a simple design with screw‑terminal connections for easy installation. The regulator includes a CD (configuration disk) with documentation and settings, facilitating quick setup.

Installation Procedure

Disconnect the generator from power. Remove the old regulator, noting the wiring connections. Install the new SSR unit using the provided bracket. Connect the voltage sensing wires (from generator output) and the excitation leads (to the exciter field). Adjust the voltage setpoint to the desired output. Verify the stability adjustment for smooth regulation. Test the unit under load and make fine‑tuning adjustments if needed.

Compliance

Complies with EMC standards, CE marked, RoHS compliant.

Conclusion
