Description
The universal input of the WD Dual series spans 18 to 72 volts.
This makes these converters ideal for 24 and 48 volt battery,
process control and telecom applications.
Coupled with these features is a low output noise of
typically less than 80 mV peak to peak. The noise is also fully
specified for RMS value and if even these impressive noise
figures aren’t enough, our applications section shows a
simple add on circuit that can reduce the output noise to less
than 10 mV p-p.
Full isolation is provided to help cut ground loops in
industrial systems, where unknown input power quality could
create havoc with sensitive, high precision analog circuitry.
No extra components or heatsinking are required for most
applications saving you design time and valuable PCB space.
