ABB DCPT-01 3AUA0000108087 Drive 

1. Key Parameters

• Order Code/Part Number: 3AUA0000108087 (unique identifier for procurement and documentation)
• Product Model: DCPT-01 (ABB’s compact DC drive series for low-power applications)
• Core Function: Speed/torque control of separately excited or shunt-wound DC motors
• Rated Output Current: 10A (continuous); 20A (peak, 1-minute duty cycle)
• Rated Output Voltage: Up to 400V DC (matches common DC motor voltage ratings)
• Input Power Supply:
  • AC: 3-phase, 380V~480V (50/60Hz); Single-phase, 200V~240V (optional, for low-power models)
  • Voltage tolerance: ±10%
• Motor Compatibility:
  • Type: Separately excited DC motors, shunt-wound DC motors
  • Maximum motor power: 4kW (at 400V DC, 10A output current)
• Control Modes:
  • Speed control (via analog input: 0~10V DC or 4~20mA DC)
  • Torque control (optional, via current reference input)
• Speed Regulation Accuracy: ±0.5% of rated speed (static); ±1% of rated speed (dynamic)
• Protection Functions:
  • Overcurrent protection (OCP): Trips at 150% of rated current
  • Overvoltage protection (OVP): Trips at ≥450V DC output
  • Undervoltage protection (UVP): Trips at ≤320V AC input (3-phase)
  • Overtemperature protection (OTP): Trips at ≥85℃ (heatsink temperature)
  • Short-circuit protection (SCP): Instantaneous trip for output short circuits
• Communication Interface: 1× RS-485 port (Modbus RTU, for remote monitoring/control)
• Dimensions (W×H×D): 120mm × 180mm × 100mm (compact design for space-constrained cabinets)
• Operating Temperature Range: 0℃~+50℃ (14℉~122℉); Derating required above 40℃ (10% current reduction per 10℃)
• Storage Temperature Range: -20℃~+85℃ (-4℉~185℉)
• Protection Class: IP20 (module body); Complies with IEC 61800-5-1 (safety for adjustable speed drives)

2. Product Features

• Compact & Space-Saving: Slim profile (120mm width) enables high-density installation in small control cabinets—ideal for applications with limited space (e.g., laboratory equipment, small conveyors).
• Dual Input Compatibility: Supports 3-phase AC (380V~480V) or optional single-phase AC (200V~240V) input, adapting to diverse power supply configurations in industrial and commercial settings.
• Smooth Speed Control: Delivers precise speed regulation (±0.5% static accuracy) with low ripple output, ensuring stable motor operation for applications requiring consistent speed (e.g., printing machines, precision conveyors).
• Integrated Protection: Comprehensive safeguards (overcurrent, overvoltage, overtemperature) prevent damage to the drive, motor, and connected equipment—reducing downtime and maintenance costs.
• Easy Configuration: No specialized software required; parameters (speed reference, acceleration/deceleration time) can be set via front-panel potentiometers or analog inputs—simplifying commissioning for on-site technicians.
• Remote Monitoring: RS-485 (Modbus RTU) interface enables integration with PLCs or SCADA systems for remote speed adjustment, status monitoring, and fault diagnosis—enhancing operational flexibility.
• Industrial Durability: Flame-retardant plastic housing (UL94 V-0) and robust heatsink design ensure reliable operation in dusty or vibration-prone environments (e.g., small manufacturing workshops, packaging lines).

3. Application Fields

• Small Industrial Machinery: Controls DC motors in small conveyors, mixers, and centrifuges in food processing, pharmaceutical, and laboratory settings—ensuring precise speed control for consistent product quality.
• Material Handling: Regulates DC motors for small belt conveyors, lift tables, and palletizers in warehouses and distribution centers—supporting smooth material transport with adjustable speed.
• Packaging Equipment: Drives DC motors in labeling machines, filling machines, and sealing equipment—maintaining stable speed to avoid packaging errors (e.g., misalignment, uneven sealing).
• HVAC & Building Automation: Controls DC fans and pumps in small HVAC systems, air purifiers, and water circulation units—optimizing energy efficiency via variable speed operation.
• Automotive & Electronics Manufacturing: Powers small DC motor-driven tools (e.g., precision drills, soldering stations) in electronics assembly lines—ensuring controlled torque and speed for delicate operations.

4. Precautions

• Motor Compatibility: Ensure the drive’s rated output current (10A) and voltage (up to 400V DC) match the DC motor’s specifications—overloading will cause overheating or drive failure.
• Input Power Wiring: For 3-phase input, confirm correct phase sequence; for single-phase input, use the designated terminals (do not connect single-phase power to 3-phase terminals, as this will damage the drive).
• Derating at High Temperatures: Above 40℃, reduce the drive’s continuous output current by 10% per 10℃ (e.g., 9A at 50℃) to prevent overtemperature tripping—install forced-air cooling if ambient temperature exceeds 40℃.
• Grounding Requirements: Connect the drive’s protective ground terminal to a dedicated earth ground (≤4Ω resistance) to ensure safety and reduce electromagnetic interference (EMI).
• Maintenance Safety: Disconnect input power and discharge the DC bus (wait ≥5 minutes) before servicing the drive—capacitors may retain charge, posing electric shock hazards.
• EMI Mitigation: Use shielded cables for motor and control wiring; route power cables separately from signal cables (≥30cm spacing) to minimize EMI-induced noise in control signals
