Mitsubishi's FR-A540L-90K-EC model is part of the productive FREQROL FR series of frequency inverters. This device is engineered to handle substantial loads with a rated current of 180A. It operates within a voltage range of 3-phase, specifically from 380V to 480V. Built to meet rigorous conditions, the inverter can manage a power facility capacity of VT and Light VT, both rated at 137 kVA.

In terms of physical attributes, the inverter has a weight of 57 kg and features an open type protective structure with an IP00 rating. For cooling, it employs a forced air cooling method to ensure optimal operation. The device also boasts a frequency setting resolution that can adjust as finely as 0.01 Hz, with an allowance for frequency fluctuations of ±5%. It is designed for high-altitude installations, functioning effectively at altitudes reaching up to 1000 meters above sea level.

The FR-A540L-90K-EC model is manufactured for environments with an ambient humidity of 90% relative humidity or lower, avoiding condensation effects that could damage the electronics. It is built to withstand vibration levels of 5.9 m/s² {0.6G} or lower, maintaining performance stability. The inverter's analog input ranges between 0 to 5V DC, 0 to 10V DC, 0 to ±10V DC, and 4 to 20 mA DC, which allows for flexibility in control signal processing. Lastly, this model is capable of withstanding storage temperatures from -20°C to +65°C, showcasing its robust design for various application scenarios.
