Reliance 0-56942-1-CA Regulator Board for GV3000 Drives

Short Description: Reliance 0-56942-1-CA is a legacy regulator PCB board tailored for Reliance GV3000 series AC variable frequency drives. This discontinued control card manages voltage and current regulation for the drive power section, stabilizes internal operating power and delivers closed-loop signal conditioning. The suffix -CA denotes a specific hardware revision variant of base part 0-56942-1, widely stocked as spare replacement for existing GV3000 drive cabinets.

Product Functions

• Precise voltage and current regulation for GV3000 AC drive internal circuits
• Stabilize control power supply for drive logic and gate driver circuits
• Process feedback signals from current/voltage sensing components
• Built-in overvoltage, overcurrent and thermal protection monitoring
• Signal conditioning for motor speed and torque closed-loop regulation
• Standard slot-mounted PCB assembly for GV3000 drive rack installation
• Transmit fault status signals to main drive control logic for trip protection

Application Scenarios

• Reliance GV3000 series AC variable frequency drive systems
• Manufacturing production line AC motor speed control cabinets
• Paper mills, conveyor systems, metal processing and extrusion machinery
• Legacy industrial drive maintenance, retrofit and spare part inventory
• Heavy industry plants with existing Reliance VFD installations
• Emergency replacement for failed regulator boards in running GV3000 drives
