Produktbeschreibung
Produktbeschreibung
This unit installs into Delta 1U/2U or compact embedded power subracks, converting single-phase AC into telecom-grade stabilized DC for micro station power systems.
Problemlösung & Einsatznutzen
Solves space limitation in shallow outdoor enclosures, remote maintenance difficulties, and premature shutdowns caused by unstable utility voltages.
Zielgruppe und Einsatzbereich
Engineered for 4G/5G small cells, FTTH optical distribution hubs, railway signaling relay boxes, and industrial embedded power supplies.
Wesentliche Vorteile
- Compact Shallow-Depth Chassis: Reduced depth and light weight facilitate mounting in tight wall-mount boxes and shallow outdoor enclosures.
- Wide Utility Grid Adaptability: Operates from 85V to 300V AC, continuing to deliver stable derated power down to 90VAC input.
- Arc-Free Hot-Swap & Current Sharing: Plug-and-play design with autonomous parallel load-sharing prevents single-point system outages.
- Low Acoustic Noise Profile: Acoustically optimized airflow path ensures ultra-quiet operation compliant with urban residential site requirements.
