It handles **0.75 kW in heavy-duty mode** (constant-torque: conveyors, extruders, hoists) and **1.5 kW in normal-duty mode** (variable-torque: centrifugal pumps, HVAC fans, cooling towers). It runs on a **460V 3-phase** supply and is in active production with full manufacturer support. For maintenance teams keeping a line running, the practical difference between a stocked independent distributor and an authorized channel with 4–8 week lead times can be the difference between a shift lost and a shift saved. ## Key Specifications | Parameter | Value | |---|---| | Series | Delta C2000 | | Heavy-duty rating | 0.75 kW / 1 HP (3.8 A) | | Normal-duty rating | 1.5 kW / 2 HP (4.0 A) | | Input | 460V AC, 3-phase | | Weight | 2.6 kg | | Production status | Active | | Alternate MPN | VFD015C43A-21 | ## Duty Ratings and Motor Sizing The dual kW rating is a thermal-envelope decision, not marketing. **Heavy-duty (HD) — 0.75 kW / 3.8 A:** 150% overload for 60 seconds. Size here for constant-torque loads where the motor works against a fixed mechanical resistance regardless of speed — screw compressors, positive-displacement pumps, and conveyors that start under load. The IGBT stage runs at a higher baseline current, so the kW headroom is tighter. **Normal-duty (ND) — 1.5 kW / 4.0 A:** 120% overload for 60 seconds. This maps to variable-torque loads where torque demand drops with the square of speed — centrifugal pumps, axial fans, and cooling towers. If your application is a pump or fan and you are not starting against a closed damper, size to the ND rating and save on the drive frame. If you are unsure: size to HD. A drive that trips on overload during commissioning costs more in downtime than the frame-size delta. ## Carrier Frequency Trade-off The C2000 family allows carrier frequency adjustment, typically 2–15 kHz. Raising the carrier quiets audible motor noise — relevant in occupied spaces like hospital air handlers or office-building AHUs — but increases IGBT switching losses. The practical rule: every 1 kHz above the factory default derates continuous output current by roughly 2–3%. For a 0.75 kW drive running a fractional-HP motor, the thermal margin is generous enough to run at 8–10 kHz without derating. For 1.5 kW ND applications near full load, monitor heatsink temperature if you push the carrier above 6 kHz. ## Installation Notes - **Mounting:** 2.6 kg — wall-mount on rigid backplane. Avoid sheet-metal enclosures that amplify switching-frequency vibration. - **Cooling clearance:** Maintain 50 mm minimum above and below for convection. In sealed enclosures (IP54+), account for drive internal losses in your cabinet thermal budget. - **Motor cable:** Use shielded cable for runs exceeding 10 meters, especially with sensitive instrumentation on the same supply. - **Branch-circuit protection:** Size the upstream breaker or fuse per local code for the drive input current rating. A 460V 3-phase supply requires proper short-circuit coordination. ## Compatibility and Cross-Reference **VFD015C43A vs VFD015C43A-21:** Same drive, same hardware. The \"-21\" is the market-standard suffix used by DigiKey, Mouser, and most authorized distributors. If your BOM or procurement system lists either MPN, proceed with confidence. **Scaling within C2000:** The C2000 spans from sub-1 kW to several hundred kW. The VFD015C43A sits at the lower end — common for auxiliary pumps, compact cooling fans, and light material-handling drives. Larger frames retain the same parameter structure, so commissioning experience transfers. **Accessories to plan for:** | Accessory | When needed | |---|---| | EMI filter | Installation sharing supply with PLC or instrument circuits | | Braking resistor | Rapid deceleration of high-inertia loads | | Remote keypad cable | Drive mounted inside sealed enclosure; keypad on cabinet door | ## Sourcing from AO Ctrl We stock **40 units** of the VFD015C43A / VFD015C43A-21 in our Shenzhen facility, available for immediate dispatch. Our reference price of **** positions well below the typical authorized-distributor range (– at major North American sources), reflecting the speed and cost advantage of the Shenzhen electronics supply chain — shorter path from factory floor to your loading dock, without the layered margins of a multi-tier authorized channel. **What this means for your timeline:** Authorized channels for Delta C2000 drives in Southeast Asia and the Middle East commonly quote 4–8 weeks. Our Shenzhen warehouse dispatches within 48 hours of order confirmation. For a maintenance team facing a downed production line, the arithmetic is straightforward. **To order:** Submit an RFQ through the form on this page. Include target quantity, required delivery date, and destination. We quote within one business day and arrange DDP terms for most destinations across Asia and the Middle East. --- ### FAQ **What is the difference between VFD015C43A and VFD015C43A-21?** They are the same drive. The \"-21\" suffix is the market-standard designation. Either MPN in your BOM refers to identical hardware. **Can this drive run a 2 HP motor?** Yes — in normal-duty mode the drive is rated for 1.5 kW (approximately 2 HP) on variable-torque loads like fans and centrifugal pumps. For constant-torque applications, size to the 0.75 kW (1 HP) heavy-duty rating. **What is the input voltage tolerance?** The C2000 series typically accepts +10% / -15% of nominal input voltage. For precise tolerance and ride-through specifications, refer to the datasheet (download link on this page). **What wire gauge for the power terminals?** Wire gauge depends on local electrical code and upstream protection rating. For the 3.8 A (HD) to 4.0 A (ND) current levels at the drive input, 1.5 mm² (16 AWG) is generally adequate. Always verify against your installation's short-circuit current rating and local regulation.","metaTitle":"Delta VFD015C43A / VFD015C43A-21 C2000 VFD 0.75kW HD 460V","metaDescription":"Delta C2000 VFD015C43A-21 AC drive: 0.75kW HD / 1.5kW ND, 460V 3-phase. 40 units in Shenzhen stock.
