Rated 17 A continuous output at 6.5 kVA, it covers pumps, conveyors, fans, and small compressors in that power band without oversizing the cabinet footprint. ## Input envelope and what it tolerates on plant power Three-phase 200-240 VAC at 50/60 Hz is the rated input, with ±10% voltage tolerance (180-264 VAC) and ±5% frequency tolerance (47-63 Hz) — enough headroom to ride through the brown-outs and small generator excursions seen on factory feeders. Rated input current is 19.6 A, which sets the upstream breaker and wire sizing, not the motor nameplate. ## Output side: from low-end torque to 400 Hz Output frequency spans 0.1-400 Hz with a carrier window of 1-15 kHz; maximum output voltage tracks the input rail proportionally. At the default carrier the motor runs quiet; pushing toward 15 kHz cleans up acoustic noise but trims continuous output current, a tradeoff that matters on constant-torque loads like conveyors run near rated rpm. Sensorless vector control is the headline control mode — usable down to low Hz without encoder feedback, which is the practical reason the VFD-M is specified where low-speed holding torque matters but an encoder retrofit is not in the budget.","metaTitle":"Delta VFD037M23A VFD-M Drive, 3.7 kW / 5 HP, 17 A","metaDescription":"Delta VFD-M VFD037M23A sensorless vector micro drive, 3.7 kW (5 HP), 17 A output on 3-phase 200-240 VAC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["AC Drive (VFD) 240V"],"specifications":{"title":"VFD037M23A","Weight":"3.2 kg","Product no":"VFD037M23A","description":"General Sensorless Vector Control Micro Drives","Input Rating":"Rated Input Current : 3-phase , 19.6 Rated Voltage, Frequency : 3-phase 200-240VAC, 50/60Hz Voltage Tolerance : ±10% (180~264 VAC) Frequency Tolerance : ± 5% (47~63 Hz)","Product type":"General Sensorless Vector Control Micro Drives VFD-M Series","Version Type":"A","Input Voltage":"23 - Three phase 230V","Output Rating":"Rated Output Capacity (kVA) : 6.5 Rated Output Current (A) : 17 Maximum Output Voltage (V) : 3-phase Proportional to Input Voltage Output Frequency (Hz) : 0.1~400 Hz Carrier Frequency (kHz) : 1-15","Voltage Class":"230V Class","Cooling Method":"Fan Cooled","Shipping Weight":"5 Kg","lifecycle_stage":"current","Voltage Tolerance":"±10% (180~264 VAC)","Estimated Lead Time":"Usually ships in 1-10 working days.","Frequency Tolerance":"± 5% (47~63 Hz)","Rated Input Current":"3-phase , 19.6","Output Frequency (Hz)":"0.1~400 Hz","Carrier Frequency (kHz)":"1-15","Rated Output Current (A)":"17","Rated Voltage, Frequency":"3-phase 200-240VAC, 50/60Hz","Applicable motor capacity":"037 - 5 HP(3.7kW)","Maximum Output Voltage (V)":"3-phase Proportional to Input Voltage","Rated Output Capacity (kVA)":"6.5","Max.

The M23A suffix designates 3-phase 200-240 VAC input at 19.6 A rated input current, while the M21A suffix designates single/3-phase 200-240 VAC input at 11.5/7.6 A. Motor output ratings differ (17 A vs 10 A continuous), and the input-side wiring, fusing, and breaker sizing have to be re-rated — a panel swap is a wiring change, not a footprint change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/delta/VFD037M23A","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/VFD037M23A when reusing this data.
