PA1008-050HEB050-181-V0-A3 5V 0.5A AC DC Adapter 2.5W Power Supply

The PA1008-050HEB050-181-V0-A3 (also known as PA1008 Adapter or PA1008-1HE) is a high-performance ac adapter, power adapter, ac dc adapter and ac/dc adapter, also serving as a reliable 5V 0.5A Adapter, 2.5W Power Supply, 100-240Vac Adapter, CE Certified 5V Charger, and RoHS Compliant 5V Adapter compatible with WM1018 and other small electronic devices requiring 5V 0.5A DC input. This universal ac plug in adapter supports a wide rated input voltage of 100-240Vac, with an operating input range of 90-264Vac 47-63Hz, a maximum AC input current of 300mA, an inrush current of less than 20A at 115Vac and 40A max at 230Vac cold start with full load, making it compatible with global power grids for worldwide use. This alternating current adapter delivers a stable DC5V ±5% rated output voltage, with an output current range of 0 to 500mA, and a total rated output power of 2.5W. It achieves a minimum conversion efficiency of 63% at full load, meets CEC regulation level V requirements, features a maximum output ripple of 20mV and maximum output noise of 50mV at 500mA load, tested with 20MHz bandwidth oscilloscope via a 10μF electrolytic capacitor in parallel with a 0.1μF ceramic capacitor at the output connector. This ac of dc adapter features precise timing characteristics, including a maximum turn-on delay time of 2 seconds, maximum rise time of 10ms, voltage overshoot of less than 8% of the nominal voltage during power on, and a minimum hold up time of 10ms at full load across the full input voltage range. It is equipped with comprehensive auto-recover protective functions, including short circuit protection that limits peak output voltage and input power with automatic recovery after fault removal, over current protection triggered at less than 200% of the rated output current, and over voltage protection set at less than 120% of the rated output voltage. This ac power adapter meets strict international safety and EMC standards, with safety compliance to CB scheme IEC60950-1:2005 (2nd Edition), EMI compliance to CE EN55022:2006 Class B, EN55024, FCC ANSI C63.4 Class B, VCCI CISPR 22 Class B, and Australia C-Tick standards. It passes ESD immunity tests with ±4kV contact discharge and ±8kV air discharge, 1kV EFT on AC power lines, and 1kV differential mode surge test, with no damage and full normal operation after all tests. It features a maximum leakage current of under 250uA, passes a 3000Vac 50Hz hi-pot test for 1 minute between primary and secondary with less than 10mA test current, and delivers a minimum insulation resistance of 50MΩ at 500VDC between input/output plug and plastic case. This adapter delivers a demonstrated MTBF of 40,000 hours of continuous operation at 25℃, with a component temperature rise of less than 85℃ and case temperature rise of less than 35℃ at full load and 25℃ ambient temperature. It has passed 100% full load burn-in test for 4 hours at 40±5℃, 3 drops from 1m height on a hard wooden surface, and 10,000 times AC input ON/OFF cycle test, with no performance degradation or damage after all reliability tests. It operates reliably in 0℃ to 40℃ ambient temperature with maximum 75%RH non-condensing operating humidity, and can be stored in -20℃ to 70℃ environment with maximum 95%RH non-condensing storage humidity, suitable for installation at altitudes up to 10,000 feet. With a compact PC+ABS plastic housing with dimensions of 59mm(L) X 27mm(W) X 40mm(H), a 2-pin plug-in type AC input, a 1200mm long UL1185 22AWG output cable, and a 5.52.112mm barrel straight DC plug with built-in 103 capacitor, this PA1008 adapter is the ideal power solution for small electronics, sensors, and other 5V 0.5A DC powered devices.
