DELTA ESR-48/10BE DPR48/10-B-DCE Power Supply Module

DELTA ESR-48/10BE DPR48/10-B-DCE Power Supply Module

Product Description:

The DELTA ESR-48/10BE is a high‑efficiency 48V DC hot‑swappable rectifier module designed for telecommunications power systems. This module is also referred to as DPR48/10-B-DCE – a designation frequently used in inventory records and Bill‑of‑Materials (BOM) listings, where “B” indicates a module variant with a specific current rating and interface configuration. Manufactured by Delta Electronics, a world‑leading provider of power and thermal management solutions, the ESR‑48/10BE provides regulated -48V DC output power for telecom infrastructure equipment.

Key Technical Specifications

Key Features & Functions

• 48V Telecom Power – Delivers regulated -48V DC power commonly used in telecommunications systems, base stations, and network equipment.

• Hot‑Swappable Design – The module can be inserted or removed without powering down the entire system, enabling live maintenance and minimizing service disruption. All adjustment and operation are performed from the system front for convenient installation and expansion.

• Active Power Factor Correction (PFC) – Interleaved PFC technology achieves a power factor greater than 0.99 and low AC input current harmonic distortion (THD < 5%), effectively eliminating harmonic pollution to the grid.

• High Efficiency – ≥ 90.5% efficiency reduces heat generation and lowers operating costs.

• Advanced Protection – Built‑in protections include output over‑current, over‑voltage, over‑temperature, and short‑circuit protection.

• High Power Density – Compact design with power density greater than 2 W/cm³ (34 W/inch³) saves valuable rack space.

• Intelligent Monitoring – Compatible with Delta power system controllers via RS‑232 or optional TCP/IP card for local/remote centralized monitoring.

• Wide Operating Range – Accepts AC input from 90 V to 300 V, with tolerance up to 380 Vac without damage.

• Status LED Indicators – Front‑panel LEDs provide clear visual indication of operating status: load current level (LOAD), AC input power (AC ON), equalize charge (EQU), current limit mode (CL), rectifier fault (RFA), and fan failure (FF).

• N+1 Redundancy – Supports N+1 redundant configurations for improved system reliability.
