The Mitsubishi FR-Z240-3.7K-UL is a FREQROL Z200 series transistor inverter engineered for variable speed control of three-phase induction motors up to 5 HP. This 3.7 kW variable frequency drive accepts 3-phase input at 380–480 V, 50/60 Hz and delivers proportional 3-phase output. The compact inverter measures 15.75 in. H × 9.84 in. W × 7.48 in. D with IP20 enclosure protection and operates at rated 9 A.
The bundled FR-PU01E parameter unit provides hands-on control and diagnostics via a 13-character × 4-line LCD display and 24 tactile membrane keys. Operators can monitor real-time frequency (Hz), current (A), and voltage (V); adjust frequency from 0 to 120 Hz; and select from PU operation, external operation, or jog modes. Forward and reverse rotation control, parameter read/write functionality, and mode-select capability round out the control interface.
