Specifications typical at Ta=+25℃, resistive load, nominal input voltage and rated output current unless otherwise noted.
Transient recovery time is measured to within 1% error band for a step change in output load of 75% to 100%.
Ripple & Noise measurement bandwidth is 0-20 MHz measured with a 1μF M/C.
These power converters require a minimum output loading to maintain specified regulation, operation under no-load conditions will
modules; however,modules; however, they may not meet all specifications listed.
not damage these they may not meet all specifications listed.
All DC/DC converters should be externally fused at the front end for protection.
We recommend to protect the converter by a slow blow fuse in the input supply line.
That “natural convection” is about 20LFM but is not equal to still air (0 LFM).
Specifications are subject to change without notice.
