| GENERAL DESCRIPTION The Pacemaster 12 packaged DC drive is a three phase, full wave, AC to DC converter for precise control of motor speed and torque. The drive package consists of a panel mounted Pacemaster 12 power module, DC loop contactor, current limiting fuses for both the AC line and DC motor armature and 115 VAC control transformer. The Pacemaster 12 packaged drive is an armature reversing, fully regenerative unit providing control in all four quadrants. Available in six (6) basic packaged drives through 300 HP, it has been developed for powering high speed automatic machinery where controlled torque, starting, stopping, direction and speed changing are critical factors. Its fast response to machine requirements helps to provide improved productivity. The Pacemaster 12 is a high performance unit with conservatively rated power components. Each packaged drive is selectable for operation by either 230 or 460 volts AC. In addition, horsepower, armature voltage feedback, scaling and field current are jumper selectable to match the requirements of the DC motor. Pretested logic semi-conductors, high frequency and transient voltage protection, adjustable current limit and solid state motor overload protection assist in providing reliability of the system and protection of the driven equipment. Pacemaster 12 packaged drives are designed and manufacͭtured to comply with applicable standards established by the National Electrical Code and NEMA for industrial motor and control equipment. Standard Pacemaster 12 power modules are UL Recognized. These Pacemaster 12 packaged drives can be supplied as UL Listed. Consult your CMC representative for further information. | |||||||||||||
| PACKAGED DRIVE ACCESSORIES WOUND FIELD DC MOTORS - 5-300 HP constant torque and constant horsepower integral frame DC motors supplied with a variety of enclosures and options to meet the application requirements. Օ ISOLATION TRANSFORMERS - 7.5-330 KVA drive isolation transformers, three phase, delta primary, wye secondary, in a NEMA 1 enclosure to provide drive isolation and/or AC line voltage matching. OPERATOR CONTROLS - Standard and custom operator control stations, operating devices and meters to provide control and visual indication of the driven equipment. | |||||||||||||
