WEG CFW500 VSD CFW500A0038T4 25HP 38.0A 380-480V

The WEG CFW500A0038T4 is a CFW500 variable-speed drive rated at 38.0A continuous output, controlling three-phase induction motors up to 25HP (18.5kW) on a 380-480V 3-Phase supply. WEG is a global leader in motors and drives, and the CFW500 family is widely deployed for pump, fan, compressor and conveyor control across Saudi industry. Razz Middle East stocks the CFW500A0038T4 in Saudi Arabia with SAR pricing and a 4-hour RFQ response.

Technical Overview The CFW500A0038T4 uses WEG's vector-control platform to deliver scalar V/f, quadratic V/f, WEG's VVW flux control and full sensorless-vector control for tight speed and torque regulation without an encoder. A high-frequency IGBT output stage provides 0-500Hz operation, and the drive carries a complete protection suite — over-current, over/under-voltage, motor overload (I²t), earth fault, short circuit and over-temperature. Built-in Modbus RTU (RS-485) and an integrated PID loop allow the CFW500A0038T4 to run closed-loop pressure, flow or level control standalone, or integrate into plant DCS/PLC systems. WEG's plug-in accessory architecture lets the CFW500A0038T4 accept optional fieldbus modules (PROFIBUS DP, CANopen, DeviceNet, EtherNet/IP and PROFINET), I/O expansion and a remote HMI, so the same base drive can be standardised across mixed Aramco, SABIC and utility control networks without changing the power section. The control firmware includes flying-start, DC-braking, multi-speed presets, skip-frequencies to avoid mechanical resonance, and a programmable SoftPLC for simple machine logic inside the drive.

Performance & Specifications Continuous output is 38.0A for motors up to 25HP (18.5kW), with 150% overload for 60 seconds and 200% for 0.5 seconds for high-inertia starts. The 380-480V 3-Phase input suits Saudi grid conditions, and the IP20 chassis is rated -10°C to +50°C with published derating above 40°C for the Kingdom's high ambient temperatures. Variable-torque pump and fan loads benefit from the drive's energy-optimisation and skip-frequency functions. Carrier (switching) frequency is adjustable so installers can trade acoustic noise against thermal derating, and the CFW500A0038T4 supports long motor-cable runs typical of large process plants where the drive sits in an air-conditioned switchroom and the motor is hundreds of metres away in the field. An internal braking transistor (DBN versions) handles regenerative loads such as decelerating high-inertia fans and downhill conveyors, dissipating energy in an external resistor to give controlled, repeatable stopping without over-voltage trips.

Applications in Saudi Arabia The CFW500A0038T4 controls high-lift and transfer pumps at SWCC and National Water Company stations around Riyadh, Dammam and Jeddah, cooling-tower and process fans at SABIC petrochemical plants in Jubail and Yanbu, conveyor and crusher drives at MAADEN mining operations in Ras Al-Khair, and HVAC and chilled-water plant across the NEOM, Red Sea and Qiddiya giga-projects. Variable-speed control delivers energy savings, soft starting and precise process regulation in line with the Saudi Energy Efficiency Center programme and Vision 2030 targets.
