What power and voltage ranges do SmartD Clean Power VFDs cover?
The SmartD SDB series we carry spans 26 models. SDB-1 drives run on 3-phase 400–480 VAC and cover 5 to 125 HP (4–90 kW). SDB-2 drives run on 3-phase 600 VAC and cover 7.5 to 150 HP (5.5–110 kW). Normal-duty output current reaches 165 A at the top of each range, and the drives are built in frame sizes S2, S3, S3L, S4 and S5.
Do SmartD drives need an external harmonic filter or line reactor?
No. SmartD Clean Power VFDs are built on silicon carbide (SiC) power electronics and SmartD’s patented modulation algorithms, which keep input current distortion (THDi) below 5 % natively. That meets IEEE 519 and IEC 61000-3-12 without harmonic filters or line reactors, and because the output is a pure sine wave, no dV/dt or sine filter is needed on the motor side either.
What is the difference between SmartD SDB-1 and SDB-2 part numbers?
The second character block identifies the supply voltage. SDB-1 models (for example SDB-1-2300-A) are rated for 3-phase 400–480 VAC, −15 % / +10 %, 50/60 Hz. SDB-2 models (for example SDB-2-2300-A) are rated for 3-phase 600 VAC with the same tolerance. The following digits indicate the motor power, so SDB-1-2300-A and SDB-2-2300-A are both 40 HP (30 kW) drives on different voltages.
Which communication protocols and I/O are built into SmartD VFDs?
Every SmartD SDB drive includes two RJ45 Ethernet ports supporting Modbus TCP and BACnet IP, plus Bluetooth Low Energy (BLE) for setup from a mobile app. On-board I/O is 6 digital inputs, 3 relay outputs, 3 analog inputs and 2 analog outputs. Two Safe Torque Off (STO) inputs rated SIL 3 / PLe and a fire mode are standard.
Does a SmartD VFD support regenerative braking?
Yes. The integrated Active Front End (AFE) returns braking energy to the supply, so SmartD drives provide full regenerative braking without a braking resistor or chopper. The same AFE gives the drive a near-unity power factor.
How do I get pricing on SmartD drives?
Click Request Quote on any SmartD product page, call us toll-free at 1-877-PARTS-57 (727-8757), or email sales@industrialautomationco.com with the part numbers you need. During business hours we generally return quotes in ten minutes or less.
What is the lead time on SmartD Clean Power VFDs?
SmartD drives are supplied with a lead time of 8–12 weeks after receipt of order. 15 of the 26 models are available to order now; the remaining 11 are listed for pre-order ahead of SmartD’s full catalogue release in March 2027 and are tagged Pre-order on the product page. Confirm current delivery with your quote.
How do SmartD drives ship?
SmartD frame S3 and S4 drives weigh roughly 66 to 133 lb (30 to 60.4 kg), so they ship by freight rather than parcel. Freight cost and transit time are confirmed with your quote. Contact us if you need expedited delivery on an available model.
