Information About FR-E520-3.7K
The FR-E520-3.7K belongs to Mitsubishi Electric's FR-E500 series of compact frequency inverters developed for industrial motor control applications. It operates with a three-phase 200–240 VAC power supply and delivers variable-frequency output to regulate motor speed according to programmed operating parameters. The drive incorporates Soft-PWM control technology to reduce motor operating noise and supports communication options including RS-485 and CC-Link through compatible equipment. Its integrated control and protection functions make it suitable for conveyor systems, pumps, fans, machine tools, and general-purpose industrial automation.
Key Features:
-
Variable Frequency Control: Adjusts AC motor speed by regulating output frequency.
-
Motor Capacity: Supports three-phase motors rated up to 3.7 kW.
-
Voltage Class: Designed for three-phase 200–240 VAC power systems.
-
Rated Output Current: Provides 17.5 A rated output current.
-
Soft-PWM Technology: Helps reduce motor noise during operation.
-
Overload Protection: Supports 150% overload for 60 seconds and 200% for 0.5 seconds.
-
Communication Compatibility: Supports RS-485 and optional CC-Link connectivity.
-
Cooling System: Uses forced-air cooling for thermal management.
The FR-E520-3.7K delivers the reliability and precision required for industrial motor speed regulation and automated machinery control.
