I® USTED APPLICATION - The Pacemaster Adjustable Speed Drives convert AC 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 oprtes from single phase 115 or 230 volts AC. The Pacemaster 2 drive is available from 3 to 5 HP for 230 volts AC op颩ration. ELECTRICAL CODES The Pacemaster Controllers are UL Listed and CSA Certified. AH 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 slection of standard pre-engineered modification option kits make the Pacemaster Controller a flexible unit for a wide range of industrial applications. 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. iable Y model selection | |||||||||||||||||||||||||||||||||||

STANDARD FEATURES ە Choice of open chssis or NEMA 4 enclosure. Circuit breaker for short circuit protection on NEMA 4 enclosed models. ╕ Fuses for short circuit protection on chassis-mounl controllers(optional). Pacemaster 1 is reconnectable for 115 or 230 VAC input. Օ Oprtes on 50 or 60 Hz. for worldwide applications. 颕 Conservatively rated components selected for long service life. Full-wave power conversion for smooth efficient opթration and high performance. Voltage transient protection provided by mթtal oxide suppressor (MOV) placed across the AC line to minimize the effect of high voltage spikes from the AC power source. Power cube contains ail power semi-conductors for increased reliability and minimal maintenance time. Օ Control transformer24 volt secondary isolעtes ail magnetic control and logic from the AC power source for operator protection. Relay in control circuit protects against automatic restarting after an AC power interruption and improves drive reliability. Օ Simple, easy installation wKh minimum connections and ample wiring room. Jog. by selector switch, to allow momentary motor rotation when RUN switch is depressed. Օ Operator contols can be mounted either in drive controller or at a remote location. Maximum and minimum speed adjustments. Օ Adjustable "horsepower"from 1 /4 to 2 HP and 3 to 5 HP. ו Adjustable current limit (10-150% of full load). IR (load) compensation adjustable to suit individual motor character-istics.
