A cost effective, compact and reliable PWM drive for 1/4 through 1 HP DC applications

Transcription

1 A cost effective, compact and reliable PWM drive for 1/4 through 1 HP DC applications The Micro 100 Drives have been designed with a Pulse Width Modulated (PWM) regulator to produce clean DC current to the motor. When compared to conventional SCR drives, the PWM technology provides a cost effective adjustable speed package that delivers the performance you need for a wide range of commercial, light industrial and industrial applications. The near unity form factor of the Micro 100 PWM drive is motor friendly. The clean DC current output of the drive allows cool, quiet motor operation with extended brush life. The performance matched Micro 100 PWM Motors are smaller, easier to maintain and more cost effective than comparable SCR rated motors. The improved form factor of the Micro 100 PWM drive also provides high, constant operating efficiency across the entire motor speed range. This not only reduces your energy costs but also provides a wider speed range for more precise drive operation. STANDARD FEATURES Open chassis construction on an L bracket for flexible mounting within the electrical cabinet. Fast switching Pulse Width Modulated (PWM) regulator provides: - Dynamic response to load variations. - Quiet motor operation for noise or vibration sensitive environments. Near unity form factor provides: - Clean DC output voltage from the drive to the motor. - Use of smaller, more cost effective motors in most applications. - Constant, high efficiency operation across the entire motor speed range reducing your energy costs. - Longer motor brush life reduces motor maintenance. All circuitry - sequencing, regulator, power and terminals - packaged on a single, surface mount design printed circuit board. Built-in surge suppressor helps protect semiconductors from line transients for better reliability. Electronic short circuit protection is provided by instantaneous output current sensing utilizing pulse feedback current limiting. 5K ohm speed potentiometer to vary the output speed of the drive. (Speed Pot reference models 1DN11050, 1DN11075 and 1DN21001.) 0-10 VDC isolated reference input models 1DN12050, 1DN12075, and 1DN Jumper connections for horsepower selection. Application adjustments tailor drive performance to your needs: - Separately adjustable maximum and minimum speeds set speed limits. - Adjustable current limit protects machinery, wiring and drive. - Adjustable acceleration/ deceleration rate for smooth starts, stops and speed changes. - Adjustable IR Drop Compensation for improved speed regulation. 50:1 constant torque speed range. UL Listed and C-UL Listed to meet most electrical safety codes in North America. Performance matched Micro 100 PWM DC Motors in NEMA 34, 42 and 56 frames provide the application flexibility you need from a single drive source. Two years from date of manufacture/one year in service full exchange warranty eliminates troubleshooting and quickly returns you to operation. Analog DC Drives D4-1
