SK1027

1. Designed to meet globally accepted IEC publication 320 Class
    1, that allows users to comply with industry standards in power 
    entry requirement.

3. Nickel-plated brass pins and soldering terminals.
4. Screw-on mount from front or rear (with screw type-M3).
5. Power module incorporates an IEC connector, double fuse
    holder, voltage selector, double-pole power switch, all-in-one
    easy-to-install unit.
6. Double-fuse holder designed for two fuses, single fuse & dual 
    fuse capability are both available (all 5x20mm fuses).
7. Adapts to 110-120V or 220-240V input voltage simply by
    reversing the voltage selector card.
8. Compact design and high volume production provide maximum
    flexibility and significant savings in space and cost over
    assembly of individual components.
9. All part numbers are UL, CSA and SEMKO approved.
10. SK-1027/SK-1028 with a variety of built-in filter are also
      available, see Delta EMI filter catalog for SB/NB series.
