Notes
1. For optional 3000 VDC isolation add suffix ‘-H’ to end of part number. Not all
models will support this option, please check with sales.
2. Input currents measured at nominal input voltage.
3. Typical value at full load.
4. For optional tape & reel option add suffix -TR to the end of the p/n.
Reel quantity = 500.
5. Not recommended for new design.
