Product Positioning
15
The Right Choice

• MD60 provides a product line extension from SP600
  
• It accommodates customers that only desire V/Hz
  performance in a simple package from 0.25 to 5
  HP.
• MD60 replaces to SP120 SP200 to simplify our
  product line.
• Easier to do business with RE
• Minimizes inventory at all levels
• MD60 is a more competitive product in the 0.25 to
  5 HP range. A market segment where customers
  base their buying decisions heavily on price.
