Detailed Product Description
Style: mobile charger (F8) 1) Rated output voltage: DC 5.4V 2) Output position: equipped with USB standard interface 3) Max. output current: 550mA 4) Max. output power: 3W 5) Efficiency (typical): 68% 6) Input voltage range: 110-250V 7) Input frequency range: 47-63Hz 8) Output voltage accuracy: no load voltage: 5.15-5.8V 9) Max. input regulation factor: ±10% 10) Max. load regulation: ±20% 11) Output ripple and yawp: 10% of output voltage (max.) 12) Output overpressure protection: 120-170% (adjustable as customer's request) 13) Output over-current protection: over-current protection point about 110-160% rated output current; recover point <120%; power supply protection status: online current-limited voltage drop mode 14) Charging status: charging current is the most while there is no power in battery; charging time the longest. While battery is in full condition, charging time is shorter or no need charge. When battery is full, the charging current is 10-20mA, and charging time is 2.5-3h in general conditions 15) High-pressure isolation voltage: input end - output end: AC 1.5kV/50Hz adding power, 1min: current leak <5mA 16) Working temperature parameter: working temperature coefficient is ±0.05%/°C; absolute coefficient is 0.8°C/W; absolute temperature rise is 25°C±5°C while working output is rated power 17) Environment parameter: storage environment: -20°C~+85°C; 10%~95% RH; working environment: -20°C~+50°C; 20%~90% RH (depends on using environment and power) 18) Heating loss mode: consecutive working system, machine body naturally cooling (using environment and fixing position difference to influence power usage quantity 19) Dimensions: L59 x W25 x H48mm 20) Net weight: total 55g 21) Design criterion: Nation Standard GB-4943-2001; GB17625.1-1998 22) Stability test: complies with MIL-HDBK-217 BELLCORE TR-MWT-332 Note: 1) Inspection index stated above is gotten from under condition: in the area of input rated voltage and output rated loading. Environment: 25°C, 85% RH, when there is no wind moving around 2) Output voltage DC ripple test: at the test point, with a parallel twisting string (30cm long, section: 1m², connect 0.1μF and 0.47μF capacitance with one side), respectively inspect the largest number Vp-p 100Hz of 100Hz main frequency and general ripple Vp-p max. 3) Li voltage regulation factor: input voltage changing in rated area while load is rated; Li regulation factor: load is changing from 0 to rated value
