Key Specifications Parameter Category Specification Drive Series/Base Model ACH550-BCR-012A-4 (Bypass Controller Ready) Rated Output Current 12 A Rated Output Power 5.5 kW (7.5 HP) Input/Output Voltage 380 - 480 V AC, 3-phase Enclosure Rating Designed for mounting within a bypass starter panel (specific enclosure depends on the panel builder). Control Method ABB Sensorless Flux Control (MFC) for HVAC. Key BCR Features • Dedicated logic and terminals for interfacing with external bypass contactors. • Automatic/manual transfer control between drive and bypass modes. • Motor current monitoring in bypass mode (optional). Option +C558 Embedded EtherNet/IP Adapter • Protocol: EtherNet/IP™ (Scanner/Adapter). • Ports: 2 x RJ45. • Function: Enables direct network integration for control and monitoring from a BMS or PLC (e.g., Allen-Bradley). Option +N2006 Extended I/O Kit • Function: Expands the drive's native I/O capacity to handle the complex switching logic and status monitoring of a bypass system. Option +X1558R Relay Output Expansion Kit • Function: Adds crucial Form C (changeover) relay outputs necessary to physically command the bypass contactors and provide isolated status signals (e.g., "Drive Running," "Bypass Active," "Fault"). Protection Features • Standard drive and motor protection. • Bypass system interlocks to prevent shorts. Application Focus Critical HVAC Systems with Bypass Requirements: Chilled Water Pumps, Condenser Pumps, Cooling Tower Fans, Critical Air Handling Units.
