This Specification defines the performance characteristics of SMPS based 15W AC-DC Adaptor.
INPUT OPERATING VOLTAGE
140VAC - 300VAC.
45Hz to 65Hz.
<25A Peak @ 230VAC, Cold start @ 25ºC.
< 0.25A RMS @140VAC.
>70% Under Maximum load @ 230VAC.
4.80VDC to 5.10VDC.
< 100mV. Pk-Pk.
< 150mV. Pk-Pk.
OUTPUT OVER CURRENT
> 3.0A to < 5.0A .
OVER TEMPERATURE PROTECTION
The Power supply is protected against over temperature. In case of PROTECTION over temperature the power supply goes to latch mode. the might be return to normal state by AC recycle. This is provided with a large hysteresis to avoid the PCB board over heating incase of fault conditions. the shutdown threshold at the case of Internal Room Ambient Temperature is >70ºC.
OUTPUT OVERLOAD / SHORT CIRCUIT PROTECTION
The power supply is protected against over load & short circuit . During over load & Short circuit the power supply will go to hick up mode and resumes to normal operation on removal of fault condition.
INPUT HIGH VOLTAGE PROTECTION
The Power Supply is protected against input high voltage so it can withstand up to 510VAC supply.
Operating Ambient 0ºC to + 50ºC.
Storage -15ºC to +70ºC ambient.
Operating 5% RH to 95% RH non - condensing.
Storage 5% RH to 95% RH non- condensing.
As per Test Standard IEC61000 - 4 - 5.
4KV With stand.
DI-ELECTRIC VOLTAGE WITHSTAND TEST
1.50KVAC RMS, 50Hz for one minute (trip current set at 5mA) Between Shorted Input and Output terminals.
INSULATION RESISTANCE WITHSTAND TEST
When tested with 500VDC Megger shall be >100M ohms Between Shorted Input and Output terminals.
