Product Overview
The Delta DPS 4000 Series is an indoor -48 VDC power system rated for 200 A of system current and up to 10 kW of output power, housed in a 4U, 486.6 x 300.8 x 441 mm chassis weighing 28 kg. The ESBC200-CEA fact-sheet configuration targets telecom access sites, enterprise equipment rooms and industrial DC loads that need reliable 48V power in a compact rack footprint.
The system provides a regulated -43 to -58 VDC output window and operates at 94.9% efficiency, reducing energy loss and heat dissipation in confined cabinets. Its operating range of -10 to +55 degC supports unconditioned indoor sites such as base station equipment rooms and customer premises enclosures.
DPS 4000 accepts Delta flat rectifier modules for hot-plug capacity growth and integrates system monitoring and battery management for -48 VDC plant supervision. The combination of 4U packaging, 10 kW capacity and high efficiency makes it a practical mid-size system between embedded 1U-2U plants and full-size rack power shelves.
