Input Range
VDC
These 20 Watt NT converters are ideal for battery operated
industrial,medicalcontrolandremotedatacollectionsystems.
They have achieved an exceptionally low input/output
capacitance (290 pF) that is half that of comparable models.
This low capacitance contributes to their exceptional input/
output isolation.
