Linz | 48 Vdc | 600 Amp | 28 kW Alternator

Linz PMC4-48/500 — 48 VDC, 500 A, 4-Pole DC Alternator

The Linz Electric PMC4-48/500 is a heavy-duty, 9-phase brushless DC alternator engineered for 48 V power systems in telecom, hybrid generator, and battery-charging applications. Operating from 1300–2100 RPM, it delivers up to 28 kW at 1500 RPM with ±0.5% electronic voltage regulation and exceptionally low output ripple (<1% without a battery), ensuring clean, stable DC power for sensitive loads.

Built around Linz’s PHASE 9 platform, this model integrates a forced-ventilated rectifier rated to 500 A DC (up to 380 A at 1,500 RPM), IP23 environmental protection, and thermal trips safeguarding the stator and rectifier. A SAE coupling simplifies engine integration, and the output features a high-current connection socket for straightforward and durable cabling into 48 V DC distribution panels or battery banks. It is commonly used on Aurora diesel generators for dedicated 48 V DC systems.
