I@LlSTEDI ~. APPLICATION ~ The Pacemaster Adjustable Speed Drives convert p{; line power to regu- lated direct current for adjustable speed armature control of shunt-wound or permanent-magnet DC motors. The Pacemaster 1 drive is available in ratings from 1/4 to 2 HP and operates from single phase 115 or 230 volts P{;. The Pacem aster 2 drive is available from 3 to 5 HP for 230 volts AC operation. ELECTRICAL CODES The Pacemaster Controllers are UL Listed and CSA Certified. All con- trollers are manufactured to comply with applicable standards established by National Electrical Code and NEMA for industrial motor and control equipment. OPTIONAL MODIFICATIONS AVAILABLE Unique design features of the Pacemaster models and an extensive selection of standard pre-engineered modification option kits make the Pacemaster Controller a flexible unit for a wide range of industrial appli- cations. The modification option kits can be ordered factory installed or they can be easily added in the field. MODELS AVAILABLE The Pacemaster Controllers are available in a chassis-mount or NEMA 4 enclosed configuration. STANDARD FEATURES . Choice of open chassis or NEMA 4 enclosure. .
