MAX. TEMPERATURES FOR FULL RATED OUTPUT CURRENT
Negative output voltage deviation when either load is changed.
For TVS/Zener specifications please see Application Note 107.
On dual output models, OVP protection is on positive outputs only.
With respect to minimum input voltage.
With one external 4 µF capacitor across the input.
Unit provides basic insulation up to the 75 Vdc maximum input voltage.
Maximum continuous output power not to exceed 20 Watts.
User must provide 2 A HRC (recommended) in line fuse in order to comply
with safety approvals.
Download Application Note 107 and the full data sheet from our website.
The ‘J’ suffix indicates that these parts are Pb-free (RoHS 6/6) compliant.
