switching power supply for telecommunication use

Introduction: Small communication devices widely used the communication standard voltage level of 24V/48V, the current of which is generally smaller, but the power supply equipment also requires that the management is complete, easy to use, with back-up power supply function. The AD4810D-C series are designed for the integrated power modules and power supply cabinet. Besides, the internal integrated power supply is with the following part: AC / DC rectifier power supply, charge management circuit, discharge protection circuit, power factor correction circuit, external battery port, with a total output interface, arm-loading interface, battery pack, voltage and current, charge-discharge current display circuit. Features: 1. Wide input voltage range 2. DC output voltage is continuously adjustable 3. High precision regulators 4. Low output ripple noise 5. With smart Fan (Start the fan when the temperature is over 50(±5)or the load is 50%) 6. Strong protection 7. High efficiency, small size, light weight Technique parameters: Technical DataAD4810D-CInput Voltage Range160V 280V 45Hz 63HzInput Rated Current2.8 AacPower FactorInput 220V, Output full load ≥0.98 PFOutput Voltage Range40 58 VdcOutput Current10 AdcLoad Regulation≤0.5%Power Regulation≤0.2%Phone Scale Noise Voltage300 3400Hz ≤2 mVPeak - peak Noise Voltage≤100 mVRipple Noise3.4 150KHz ≤100 mV0.15 30MHz ≤30 mV Ripple Noise Reverse3.4 150KHz ≤5 mV150 200KHz ≤3 mV250 500MHz ≤2 mV0.5 30MHz ≤1 mVInsulation StrengthInput — Shell(Ground) 1500 VacInput — Output 1500 VacOutput — Shell(Ground) 500 VacEfficiency≥85%Dynamic Response20% 100% Load Step ≤200 us170V 265Vac Step Grid≤200 usOutput Over-voltage Protection60±1 VdcOutput Current-limiting Protection11 AdcInput Low-voltage and Current-limiting Protection≤165±10 VacInput Overload Protection≤290±10 VacOver-temperature Protection90±5Battery Low Voltage Alarm46 VdcBattery Low Voltage Alarm to Recover49 VdcBattery Low Voltage Protection42 VdcBattery Low Voltage Protection to Recover48 VdcOperation Temperature-10 50MTBF100000 HrsWeight4 KgDimension (D×W×H)240mm×485mm×45mm
