Introduction: The DC converter power supply of DD-series is the dedicated power supply that we design for the communications equitment, which is a DC-DC converter that converts the 48V input power supply to 24V output power supply to provide electricity for equipments. The series use the PWM (pulse width modulation) technology with automatic current sharing function and N +1 backup function. When the power supply module failure, it can safely auto-exit and alarm, which ensure that the power supply system works normally. Features: 1. Using the inside air-cooling methods, with lower noise 2. Strong protection function 3. High reliability 4. Maintain Simply, quickly and easily 5. With the normal instructions of input and output, and alarm function 6. EMC characteristics: Consistent with the standard EN55022 CLASS B & IEC61000-4 LEVEL 3 Technique Parameter: Technical DataDD48T2430Test ConditionsInput Voltage RangeDC48V/38V 60VModule Power Surge (A)DC≤2Output Full LoadModule Input Current (A)38±1Output Full LoadOutput Float Voltage (V)27.0Factory SettingsModules are charging pressure （V）29.0Factory SettingsOutput Current （A）30Output Limit 101％～105％Load Regulation≤±0.5％Output without load to full loadPower Regulation≤±0.2％Dynamic Response100usMax20％～100％ LoadPhone Scale Noise Voltage（mV）≤2Noise meterPeak - peak Noise Voltage (mV)≤1000 20MHzEfficiency≥80％Current Deviation≤±5％Temperature Coefficien±0.02％Over-temperature protection95±5Radiator will close when temperature is over 95, which can recover.Working Temperature-10 45Storage Temperature-40 85Working Humidity5％ 95％Non-condensingInsulation StrengthLeakage Current <30mA500Vdc/1minInsulation Resistance (MΩ)≥20DC 1KVMTBF (hrs.)100000Weight (Kg)5.7DimensionRack-mounted(mm) (L × H × D)481×87×251Mini-Tower (mm)(L × H × D)88×245×370
