Overview
The WEG USCFW100073S2024ESZ frequency inverter is part of the CFW10 EasyDrive series, a compact variable speed drive designed for control and speed variation of three-phase induction motors. The CFW10 VSD line is designed for the control and speed variation of three-phase induction motors. This 200-240V inverter combines industrial-grade performance with user-friendly programming, making it suitable for a broad range of automation and motor-control applications in manufacturing, HVAC, pumping, and conveyor systems.
Key Features
- The CFW10 covers power levels from 0.18 to 4 kW (0.25 to 5 HP)
- Built-in standard keypad for parameter configuration without external trim-pots or DIP switches
- Suitable to operate with V/f or vector control
- Compact footprint reduces panel space requirements
- Simple to install and operate with standard configuration interfaces
- Built-in motor protection and control functions
Technical Specifications
The USCFW100073S2024ESZ is engineered for industrial duty and includes the following operational parameters:
- Supply Voltage: 200–240V AC (single or three-phase input)
- Output: 0–300 Hz frequency output
- Output Current (typical): 7.3 A nominal (exact rating depends on load matching; verify with motor nameplate)
- Operating Temperature: Models up to 10 A: 0–50 °C (32–122 °F) without derating; 15.2 A model: 0–40 °C (32–104 °F) without derating
- Altitude Rating: 0–1,000 m (3,300 ft) without derating; up to 4,000 m (13,100 ft) with 1%/100 m output current derating
- Control Interface: Built-in membrane keypad (no external controller required for basic operation)
- Reference Resolution: 0.1% of max. frequency (analog) and 0.01 Hz (f100 Hz) (digital)
- Protection: Motor overload, phase-loss, overvoltage, and thermal protection
- Standard Certifications: CE marking; UL approval pending for some markets
Typical Applications
The CFW10 EasyDrive is widely deployed in:
- Centrifugal and positive displacement pump systems (water supply, industrial fluids)
- HVAC fan and blower speed control
- Industrial conveyor and material handling systems
- Compressor and air handling units
- Machine tool spindle speed regulation
- General-purpose three-phase motor control requiring simple, reliable variable frequency drive operation
