Basler Electric D90-96801-100 Printed Circuit Board Card

Basler Electric D90-96801-100 is a precision printed circuit board designed as a core control module for Basler Electric’s excitation and protection systems. It functions within Basler automatic voltage regulators and excitation schemes, conditioning signals from potential transformers and current transformers, running the control logic, and driving the excitation power stage to help maintain the generator terminal voltage within specified limits. Constructed on FR-4 epoxy glass substrate, the board uses a combination of through-hole and surface-mount components and adheres to a standard Eurocard form factor measuring 160 mm by 100 mm. It is rated for operation from -40°C to +85°C and provides insulation resistance greater than 100 MΩ at 500 VDC, supporting rugged industrial environments. Onboard features include a test point matrix to verify signal integrity during commissioning and diagnostics, along with LED indicators that signal power, active regulation, and fault conditions for quick visual status checks. Typical applications cover generator voltage regulation and protection in utility substations, industrial plants, and marine power systems, where precise excitation control is essential for stable operation. Basler part number D90-96801-100 identifies this PCB as a component used in Basler excitation and protection systems.
