Motor Controllers Variable Frequency AC Drives Type VariFlex RVF Product Description The VariFlex is a simple and compact AC variable speed drive for use with 3-phase AC induction motors. The drive's first 10 parameters which are shown on the front cover are all that are required for 90% of all applications. The VariFlex employs state of the art microprocessor technology which controls all drive functions. A Digital Signal Processor syn- thesises an adjustable carrier frequency Pulse Width Modulated output controlling the Insulated Gate Bipolar Transistor (IGBT) inverter section. Another microcontroller handles the user interface functions. All printed circuit boards are manufactured using surface mount technology ensuring high quality and reliability. * AC variable speed drive for use with AC induction motors * Selectable Sensorless vector or V/f mode * Input voltage ranges: 1-ph 230VAC, 1- or 3-ph 230VAC, 3-ph 400VAC * 3 physical frame sizes: Size A, B and C * Conforms to EN 61800-3 for the second environment (Industrial sites) with integral EMC filter * All Parameters accessible both via Keypad and PC * Modbus RTU RS485 serial communications as standard on all models * PID functionality * Plug-in fieldbus option modules*1 * SmartStick option for fast and accurate drive to drive parameter transfer and storage * LogicStick PLC eliminator * I/O expansion*1 * DIN rail*2 or panel mounting *1 *2 Frame size B and C only Frame size A and B only Ordering Key RVF A 1 20 075 VariFlex AC Drive Frame size Type of AC Supply Drive voltage rating Drive kW rating Type Selection Frame Supply Drive Voltage Rating Drive Rating A: Size A B: Size B C: Size C 1: 1-phase D: 1- or 3-phase 3: 3-phase 20: 230VAC 40: 400VAC 025: 0.25kW, 0.33HP 037: 0.37kW, 0.5HP 055: 0.55kW, 0.75HP 075: 0.75kW, 1.0HP 110: 1.1kW, 1.5HP 150: 1.5kW, 2.0HP 220: 2.2kW, 3.0HP 300: 3.0kW, 3.0HP 400: 4.0kW, 5.0HP Selection Guide Voltage Rating Supply Motor rating 200-240VAC 10% 1-phase 0.25kW, 0.33HP 0.37kW, 0.55HP 0.55kW, 0.75HP 0.75kW, 1.0HP 1.1kW, 1.5HP 1.5kW, 2.0HP 2.2kW, 3.0HP 0.37kW, 0.55HP 0.55kW, 0.75HP 0.75kW, 1.0HP 1.1kW, 1.5HP 1.5kW, 2.0HP 2.2kW, 3.0HP 3.0kW, 3.0HP 4.0kW, 5.0HP 1- or 3-phase*3 380-480VAC 10% *3 3-phase*3 Frame size Size A RVFA120025 RVFA120037 RVFA120055 RVFA120075 - Size B RVFBD20110 RVFBD20150 RVFB340037 RVFB340055 RVFB340075 RVFB340110 RVFB340150 - Size C RVFCD20220 RVFC340220 RVFC340300 RVFC340400 For 3-phase supply: phase imbalance 3% (between phases) or 2% negative phase sequence (IEC 146-1-1 Immunity Class C).
