It maps to the AC Drive (VFD) 480 V family, with a 5 HP / 3.7 kW motor rating and a 460 V three-phase input (cite: cite:). The 8.2 A rated output current and 6.8 kVA output capacity are the values that govern motor pairing — sizing the drive to a motor nameplate current at or below 8.2 A continuous keeps operation inside the thermal envelope, with the standard drive (A-version) configuration supporting general-purpose applications (cite: cite: cite:). ## Input feed and operating envelope The input stage is rated 9.0 A on a 1-phase 200–240 V, 50/60 Hz feed with ±10% voltage tolerance (342–528 V noted across the broader 480 V class window) and ±5% frequency tolerance (47–63 Hz), so the upstream breaker and feeder need to be sized for that continuous input current under worst-case line drop, not just the motor full-load amps (cite: cite: cite: cite: cite:). The output frequency spans 0.1–599 Hz with a 2–12 kHz carrier; pushing carrier frequency toward the upper end quiets motor acoustic noise but the drive's continuous output current derates proportionally, so the 8.2 A figure only holds at the lower carrier settings (cite: cite: cite:). ## Supply posture and cross-reference Within the same Delta EL-series family, lower-power 230 V single-phase units such as VFD015EL21W (2 HP / 1.5 kW, 7.5 A) and VFD022EL21W (3 HP / 2.2 kW, 11.0 A) cover the smaller motor ratings, while VFD002EL43W sits in the same 460 V three-phase input class at a lower output current (5.5 A) — these are series siblings for adjacent horsepower slots, not pin-for-pin drop-ins for this 8.2 A / 5 HP position (cite: cite: cite:).","metaTitle":"Delta VFD037EL43A AC Drive, 5 HP / 3.7 kW, 460 V 3-phase","metaDescription":"Delta VFD037EL43A sensorless vector AC micro drive, 5 HP / 3.7 kW, 460 V 3-phase input, 8.2 A output.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["AC Drive (VFD) 480V"],"specifications":{"title":"VFD037EL43A","Weight":"1.7 kg","description":"Sensorless Vector AC Micro Drive","Input Rating":"Rated Input Current: 9.0 ARated Voltage/Frequency: 1-phase, 200-240 V, 50/60HzVoltage Tolerance: ± 10%(342~528V)Frequency Tolerance: ± 5%(47~63 Hz)","Product Type":"Sensorless Vector AC Micro Drive","Output Rating":"Rated Output Capacity: 6.8 kVARated Output Current: 8.2 AOutput Frequency: 0.1~599 HzCarrier Frequency: 2-12 kHz","Cooling Method":"Fan Cooling","Product Number":"VFD037EL43A","Shipping Weight":"3 kg","lifecycle_stage":"current","A - Version Type":"Standard drive","Enclosure Rating":"IP20","Output Frequency":"0.1~599 Hz","Carrier Frequency":"2-12 kHz","VFD - Series Name":"Variable Frequency Drive","Voltage Tolerance":"± 10%(342~528V)","Estimated Lead Time":"1 - 10 Working days.","Frequency Tolerance":"± 5%(47~63 Hz)","Rated Input Current":"9.0 A","Rated Output Current":"8.2 A","Rated Output Capacity":"6.8 kVA","43 - Main Input Voltage":"460V 3-phase","Rated Voltage/Frequency":"1-phase, 200-240 V, 50/60Hz","037- Applicable motor capacity":"5 HP(3.7kW)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$298.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/73cba2de77001bc49f993ad71c4d9659.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How do I get current pricing and availability for VFD037EL43A?","answer":"Pricing and current availability are confirmed at quote time through the RFQ process against the BOM quantity; no published price, stock count, or lead-time figure is asserted on this page."},{"question":"What are the key ratings on VFD037EL43A?","answer":"Rated 5 HP / 3.7 kW motor output on a 460 V three-phase input with a 9.0 A input current, 8.2 A output current, 6.8 kVA output capacity, 0.1–599 Hz output frequency, and IP20 enclosure rating."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/delta/VFD037EL43A","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/VFD037EL43A when reusing this data.
