Notes
1. For optional 3000 VDC isolation add suffix ‘-H’ to end of part number e.g.
ISA1224-H.
Note: not all options available. Please check with XP 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
