Technical Specifications

Due to its numerous technical features, the Mitsubishi FR-E520-3.7K-NA is an optimal choice for industrial applications. It accommodates a rated capacity of 7 kVA and an applicable motor capacity of 3.7 kW.

The drive can withstand an excess capacity of 150% for a maximum of 60 seconds and has a rated current of 17.5A. This model is powered by a three-phase power supply that operates at 50Hz/60Hz and has a voltage range 200V to 240V.

The drive is engineered to accommodate AC (DC) voltage fluctuations from 170V to 264V. It guarantees robust start-ups by providing 150% or greater starting torque at 1Hz and 200% or greater at 3Hz. The output voltage is maintained at 230V, with a frequency accuracy within 0.01% of the set output frequency.

The drive's optimal operation necessitates a power supply system capacity of 9 kVA, and the permissible frequency fluctuation is ±5%. The FR-E520-3.7K-NA has a carrier frequency of up to 15 kHz, which minimizes noise during operation.

The drive also incorporates a variety of protective functions, including overcurrent, overvoltage, undervoltage, and overheating protection, to ensure the equipment's safety and reliable operation. The VFD also includes a built-in PID control function that assists in the optimal regulation of process variables. The Mitsubishi FR-E520-3.7K-NA has a forced air-cooling system and an enclosed type (IP00) protective structure to regulate heat effectively.

. The drive, which weighs 2.2 kg, can operate in an ambient temperature range of -10°C to +50°C and an ambient humidity of 90%RH or lower. The temperature range for storage is -20°C to +65°C. The drive's compact dimensions, which are 128mm (W) x 140mm (H) x 150mm (D), facilitate installation in environments with limited space.

Mounting Specifications

The Mitsubishi FR-E520-3.7K-NA offers a variety of mounting options to accommodate a wide range of installation needs. It is intended to be installed at a maximum altitude of 1000 meters above sea level.

The drive's ability to endure vibrations of up to 5.9 m/s² guarantees stability and dependability in various operational environments. It also includes easily accessible terminals, which simplifies wiring and reduces the time required for installation.

Display Specifications

The drive is equipped with an LED display that displays the operating status (L.RUN, SD, RD, L.ERR), alarm (ALARM), and power application (POWER). Additionally, it furnishes real-time information regarding the operating status, set frequency, output current, and output voltage.

This enables effortless monitoring and troubleshooting, guaranteeing the system's efficient and uninterrupted operation. A keypad is also incorporated into the display to set and adjust parameters.
