FR-D740-2.2K-CHT Mitsubishi Variable Frequency Inverter AC380-500V 50/60Hz
FR-D740-2.2K-CHT Description:
The FR-D740-2.2K-CHT is a compact, general-purpose, 2.2 kW (3 HP) 3-phase 400V class inverter (variable frequency drive) from Mitsubishi Electric's FR-D700 series. Specifically designed for the Chinese market, it delivers reliable speed control for 3-phase induction motors. It features enhanced environmental durability and ease of use, making it a cost-effective and robust solution for a wide array of industrial applications requiring motor speed adjustment, energy savings, and automated process control.
FR-D740-2.2K-CHT Features:
-
Compact & Space-Saving Design: Features a slim, space-efficient construction, allowing for high-density panel mounting to save valuable control cabinet space.
-
Advanced Magnetic Flux Vector Control: Provides excellent starting torque (approx. 150% at 1 Hz) and improved speed control response, even without a PG (pulse generator) feedback card, suitable for applications with varying loads.
-
Enhanced Environment & Durability: Boasts a printed circuit board coated with a protective film for high resistance to dust and corrosive gases. It features a wide operating temperature range and conformal coating for reliable performance in harsh industrial environments.
-
Easy Setup & Maintenance: Equipped with a removable digital operator for easy parameter setting and copying. The front cover can be removed for simplified wiring. The "EZ Setup" function allows for quick commissioning by setting only basic parameters.
-
Built-in Key Functions: Includes standard features like a built-in brake transistor (for dynamic braking), Modbus RTU communication protocol (RS-485), and multiple preset speeds, reducing the need for additional external components.
-
Robust Protection Functions: Comprehensive protection for the inverter and motor, including electronic thermal overload protection, overcurrent/overvoltage/undervoltage protection, and short-circuit protection.
FR-D740-2.2K-CHT Material & Primary Use:
-
Materials: The chassis is made of high-quality, flame-retardant resin (UL94V-0). The main PCB features a special conformal coating for protection against moisture, dust, and corrosive atmospheres. Internal components utilize industrial-grade semiconductors and capacitors for long-term reliability.
-
Primary Use: Designed for speed control of standard 3-phase AC induction motors in various industrial and commercial applications, particularly where environmental robustness is needed. Typical uses include:
-
Fans, Pumps, and Blowers (for significant energy savings)
-
-
Machine Tools (e.g., lathes, grinders)
-
-
-
General Material Handling Equipment
