    Emerson 5800W 100A R48-5800a/R48-5800e DC Power Rectifier Module

    Emerson R48-5800a/R48-5800e DC Power Rectifier module 5800W 100A power supply

    R48-5800E Emerson 48V 5800E High Efficiency Telecom Rectifier
    1. High Efficiency, near 97%
    2. Hot pluggable-facilitates
    R48-5800e Emerson 48V 5800W High Efficiency Telecom Rectifier

    The eSure™ R48-5800e rectifier converts 260 to 530 VAC 3-phase supply voltages into stable nominal -48V DC voltage adjustable to the needs of the application. The R48-5800E is a constant power rectifier designed with the latest patented switchmode technology using DSP (Digital Signaling Processor) functionality for efficient operation.

    For a higher load capacity, rectifiers can be connected in parallel and intelligent control can be added with the help of a separate controller.

    Environmental conditions

    Working temperature: -5℃~45℃, derating use above 45℃   

    Storage temperature: -40℃~70℃   

    Relative humidity: ≤95%RH, no condensation   

    Altitude: ≤2000m (above 2000m requires derating to use)   

    Cooling method: forced air cooling

    Input characteristicsInput voltage range: 85Vac~290Vac, single-phase three-wire system Rated input voltage: 200Vac~250Vac Power derating input voltage range: 85Vac~176VA Do not work withstand static voltage: 415Vac Rated input current: <16A@2900W Input current: <19A@2900W/176Vac Input impulse current: <30A Allowable input grid frequency: 45~65Hz Rated input grid frequency: 50Hz/60Hz
    Output characteristicsOutput DC voltage range: 42V~58V Output DC current: 0A~60.5A Voltage stabilization accuracy ≤±0.5% Load regulation rate ≤±0.5% Voltage adjustment rate ≤±0.1% Boot upshoot amplitude ≤±1%
    Output current limiting characteristicsStepless current limit, current limit point 0A~60.5A, can be adjusted by monitoring module, current limit accuracy:≤±1.5A (42V~58V)
    Power factor and THD

    Power factor ≥0.90 @25%~50% rated output power Power factor ≥0.98 @50%~rated output power Power factor ≥0.99 @rated output power

    THD≤5% @50%~rated output power

    efficiencyThe rated efficiency is greater than 91%, and the efficiency reaches 92%.
    Current sharingThe current sharing error of the module is within ±1.5A.
    Temperature coefficient (1/℃)≤±0.01%
    Dynamic ResponseWhen the load changes step by step 50%-25%-50% or 50%-75%-50%, the response time is less than or equal to 200ms, and the overshoot is less than or equal to 5%.
    Start Time

    The power-on mode can be selected through the monitoring module:   

    1) Normal boot mode   

    The time delay from AC power-on to module output is less than 5 seconds. 2) The output starts slowly   

    This function is set by the external monitoring module to be effective, the startup time can be set by the monitoring module, the range can be set from 8s to 128s, and the accuracy is ≤±10%.
