Lamar VR2000-28-1 VOLTAGE REGULATOR, 28V (ALTERNATOR) FOR DIAMOND

The **Lamar VR2000-28-1 Voltage Regulator** (P/N **VR2000-28-1**) is a 28 V aircraft electrical component designed to regulate alternator charging voltage in compatible Diamond aircraft electrical systems. Featuring solid-state, high-frequency voltage regulation, the unit supports controlled alternator output and incorporates electrical protection and monitoring functions. The VR2000-28-1 provides overvoltage protection, ground-fault protection, low-bus warning and alternator-out indication. Integrated LED diagnostics assist with electrical system fault identification. The regulator also supports alternator paralleling applications, including load sharing between alternators of different capacities, where the installation is appropriately configured. Lamar lists the VR2000-28-1 in its FAA-PMA 28 V voltage regulator range. --- ## Applications Suitable for applicable: - **Diamond Aircraft** – Selected aircraft equipped with VR2000-28-1 alternator voltage regulators - **28 V Aircraft Electrical Systems** – Alternator charging voltage regulation - **Aircraft Electrical System Monitoring** – Low-bus warning and alternator-out indication - **Aircraft Electrical System Maintenance** – Replacement of compatible voltage regulator components Aircraft model, serial-number and installation eligibility must be confirmed against the applicable aircraft maintenance documentation and approved data. --- ## Why CJ Aerospace?
