Conditions:
*1 at 25℃ and rated input/output
*2 OBS**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 bandwidth
*4 when input voltage changed from 18V to 72V rapidly at rated input
*5 when output current changed from 0mA to rated current keeping the current of other output below minimum rated current
*6 when output current changed from minimum rated current to rated current keeping the current of other output
*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 1hour warm-up at 25℃ and rated input/output
*10 when output current changed from 25% of rated current to 75% rapidly at rated input
*11 to reduce output voltage,put a resistor between pin"0" and trimming pin
*12 to increase output voltage,put a resistor between pin"+" and trimming pin
at rated input
above minimum rated current at rated input
