Arkel ADrive 4C150 VVVF Inverter (15kW, 35A, 400V)

Meet the demands of higher-capacity elevator systems with the Arkel ADrive 4C150 VVVF Inverter. Engineered for 15 kW motors and delivering a nominal 35 A current at 400V, this Size-C model from the advanced ADrive series offers increased power handling capabilities. Available at ISF Elevator Shop, the ADrive 4C150 provides the same sophisticated vector control, superior ride comfort, energy efficiency, and essential safety features found across the range, scaled for more demanding applications.

Key Features & Benefits (ADrive 4C150):

• Optimized for 15kW Motors: Specifically designed to control elevator motors up to 15 kW (~20 HP), ideal for commercial buildings and higher-capacity lifts.
• Smooth & Quiet Operation: Ensures premium ride quality with seamless acceleration/deceleration and minimal noise/vibration, thanks to precise VVVF vector control and the Anti-Rollback function.
• Energy Efficiency: Helps reduce the elevator’s operational costs by optimizing motor power consumption, delivering significant energy savings.
• Load Independent Performance: Maintains accurate speed profiles and guarantees precise floor leveling, irrespective of the car’s load.
• Wide Motor Compatibility: Drives both standard Asynchronous (Induction) motors (open/closed loop) and high-efficiency Synchronous (Gearless) motors (closed loop, requires optional ENCABIT-Plus module).
• Emergency Evacuation Support: Fully capable of performing emergency rescue operations during power outages when coupled with external 24VDC control power and a suitable battery or UPS system.
• Comprehensive Safety Protections: Features built-in safeguards against overcurrent, over/undervoltage, short circuits, phase loss, thermal overload (drive & motor via PTC), and more. EMC certified for reliable integration.
• User-Friendly Configuration: Equipped with an integrated LCD and keypad interface for easy setup, monitoring, and diagnostics using clear, elevator-specific parameters.
• Advanced Integration: Supports auto-tuning, stores the last 256 system faults, and offers flexible communication options for integration with the main elevator control panel.

Typical Applications:

The ADrive 4C150 is highly suitable for:

• Commercial Buildings: Mid-rise office buildings, hotels, hospitals.
• Higher Capacity Residential Elevators: Larger apartment complexes or buildings with higher traffic demands.
• Goods Lifts / Freight Elevators: Applications requiring control of 15kW range motors.
• Modernization Projects: Replacing older, less efficient drives in elevators with motors up to 15kW.

Technical Specifications: Arkel ADrive 4C150

Optional Accessories:

• Arkel SCR01 ADrive Remote Keypad: Provides convenient remote access for configuration and monitoring.
• Arkel Data Key: Useful for parameter backup and easy transfer.
• Braking Resistor: Required for dissipating regenerated energy. Select based on application details (refer to ADrive manual).
• EMI Filter / Line Reactor: Recommended for optimal EMC compliance and reducing harmonics.

Frequently Asked Questions (FAQ) – Arkel ADrive 4C150

Q1: What is the maximum power rating for the ADrive 4C150?
A: This inverter is designed to control elevator motors with a power rating of up to 15 kW (approximately 20 HP).

Q2: Can it be used with gearless (synchronous) motors?
A: Yes, but like other ADrive models, it requires the additional Arkel ENCABIT-Plus module for interfacing with the necessary absolute encoders (EnDat, SSI, SinCos).

Q3: Does it support standard induction motors without encoders?
A: Yes, open-loop V/F control mode is available for asynchronous (induction) motors.

Q4: What are the main differences between this (4C150) and the lower power 4B models?
A: The primary difference is the higher power and current capacity (15kW/35A vs. lower ratings). It also uses a larger Size-C physical housing compared to the Size-B housing of the 4B models. Functionality and features are largely consistent across the ADrive series.

Q5: Is a braking resistor included?
A: No. A suitable braking resistor needs to be selected and purchased separately based on the elevator’s energy regeneration characteristics. Consult Arkel’s documentation for proper sizing.

Q6: Does it have the Anti-Rollback feature?
A: Yes, the ADrive 4C150 includes the standard ADrive Anti-Rollback (start-hold) functionality.
