Voltage tolerance is ±10% (342 V to 528 V) and frequency tolerance ±5% (47-63 Hz), so the drive rides through the typical North American 480V plant supply without complaint, including generator-backed feeds that drift on transient load steps. ## Sizing the drive to the motor load The 9.0 A rated output and 4.0 kW / 5.5 HP figure are matched to a four-pole induction motor in that power bracket — typical loads being pumps, fans, conveyors, and small compressors where sensorless vector control gives enough low-speed torque for open-loop starting without an encoder feedback card. Cooling is fan-cooled — the chassis draws air through itself, so cabinet layout matters: the intake and exhaust paths need clearance from cable bundles and adjacent heat sources, and the enclosure ambient should be budgeted against the drive's derating curve if it lives inside a sealed panel above 40°C. ## Production status and panel-builder sourcing We do not hold a standing inventory claim for this code; each build is pulled against the live distributor channel.","metaTitle":"Delta VFD040EL43W VFD, 4.0 kW, 460V 3PH, 9.0A","metaDescription":"Delta VFD040EL43W sensorless vector compact drive, 4.0 kW, 460V 3-phase input, 9.0 A rated output.

The EL-W chassis is shared, but the input voltage class differs — the VFD022EL21W takes 230V single-phase while the VFD040EL43W takes 460V three-phase, and the output ratings (11.0 A at 2.2 kW versus 9.0 A at 4.0 kW) put them in different motor-load brackets. The footprint is common, so the mounting plate does not need to change, but the supply feed, breaker sizing, and motor nameplate all need to be re-checked before a panel cutover."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/delta/VFD040EL43W","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/delta/VFD040EL43W when reusing this data.
