*1 at 25℃ and rated input/output
*2 OBQ**WC2448 satisfies the above-mentioned specifications at the same load conditions on both outputs
*3 measured by a probe at the output connector at a 0 to 100MHz bandw idth
*4 w hen input voltage changed from 18V to 72V rapidly at rated output
*5 w hen output current changed from 0mA to rated current keeping the current of other output below minimum rated current
at rated input
*6 w hen output current changed from minimum rated current to rated current keeping the current of other outputl
above minimum rated current at rated input
*7 output current of both outputs changed from 0mA to rated current identically at rated input
*8 at -20 to +71℃
*9 for 7hour period after 1 hour w arm-up at 25℃ and rated input/output
*10 w hen output current changed rapidly bew een 25% and 75% of rated current at rated input
*11 to increase output voltage,put a resistor betw een pin"0" and trimming pin
*12 to reduce output voltage,put a resistor betw een pin"+" and trimming pin
*13 out of w arranty ≧ 50℃ at input voltage from 63V to 72V
