Detailed Product Description
Model: digital camera charger (N-1200) 1) Rated output voltage: DC+4.5V 2) Output position: charge battery slot indication: +, - 3) Max. output current: 450mA 4) Max. output power: 1.8W 5) Efficiency (typical): 68% 6) Input voltage range: 110-250V 7) Input frequency range: 47-63Hz 8) Output voltage accuracy: no load voltage: 4.30-4.65V 9) Max. input regulation factor: ±5% 10) Max. load regulation: ±5% 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 lop: 110-160%, rated output current lop, recover point lop <120% lop, power supply protection status: online current-limited voltage drop model 14) Charging status: connect to power the indication light turn red, connect to MP3 player the indication light turn green, battery charge is full, the green indication turn off 15) High-pressure isolation voltage: 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. Battery is full, the charging current is 10-20mA, charging time is 3.5-4hrs in general condition 16) Working temperature parameter: input end-output end: AC1.5kV/50Hz adding power 1 minute: current leak <5mA 17) Environment parameter: working temperature coefficient is ±0.05%0C; absolute coefficient is 0.80C/W; absolute temperature rise is 250C±50C while working output is rated power0C 18) Heating loss model: storage environment: -200C∼+850C; 10%∼95%RH, working environment: -100C∼+500C; 20%∼90%RH (depend on using environment and power) 19) Dimensions: consecutive working system, machine body naturally cooling (using environment and fixing position different influence power usage quantity 20) Color and net weight: L59 x W25 x H48mm 21) Design criterion: total 58g 22) Stability test: national standard GB-4943-2001; GB176251-1998, style: comply 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: 250C, 85%RH, there is no wind moving around 2) Output volts 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-p100Hz 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. LO regulation factor: load is changing from 0 to rated value
