1/4 to 2 HP SCR Drives
OVERVIEW
The E-Series SCR Drives can control Permanent Magnet or Shunt Field DC motors in the 1/4 to 2 HP range. Each E-Drive can operate in automatic tach-follower, or master-ratio applications utilizing encoder or proximity switch lead signals. For operator convenience, LED displays can be set to show information in engineering units such as feet-per-minute. Current limiting is field adjustable in discrete increments of 4.0, 7.0, 10.0, and 12.0 Amps - eliminating the need for test meters.
