Focus III DC Drive - FOCUS 3 DC Drive

Focus 3 (1/4 to 5 HP)

The Focus 3 is a single-phase analog drive for DC
motors with power ranges from 1/4 to 5 HP. Years of proven engineering design matched with surface mount technology make this newest Focus product rugged and reliable.

Customer feedback guided the development of the Focus 3. Many features that were typically available only as options are now standard, expanding its versatility and simplifying installation.

Focus 3 provides flexibility. You can stock the complete product line with the four chassis units (two regenerative and two non-regenerative) and two enclosure kits
