Wiring a 7.5KW 10HP motor to a 220V single-phase feed means choosing a VFD that can accept that input and output three phases. These two drives in the VFDs, soft starters, and motor controls space both take 1 or 3 phase input, but they split on price and specification detail: the marddpair at a lower listed price and the zb-equipment with a model name and humidity rating. This head-to-head sorts out which one fits.
Quick Verdict
Both drives use SPWM control and accept a 220V input at 48-63 Hz from single- or three-phase sources, so the core conversion job is the same. The marddpair is the leaner choice: it lists a 40A max per phase and a United States country-of-origin line. The zb-equipment is the more complete spec sheet, with a named model, a GTIN, and a humidity rating. If you want the lower list price, pick the marddpair; if you want a documented model for panel labels or paperwork, the zb-equipment makes that easier.
| Product | Listed price | Price bar | Spec quick view |
|---|---|---|---|
| marddpair 7.5KW 10HP VFD | USD 119.39 | SPWM · 220V · 1 or 3 phase input · 40A max per phase | |
| zb-equipment 7.5KW 10HP VFD (GEGS-753) | USD 160.90 | SPWM · 220V · 1 or 3 phase input · Model GEGS-753 · Humidity 0-95% RH |
Where Each Drive Wins
The marddpair wins on sticker price. It lists at the lower end and still includes the current rating, so if you are sizing output components, that number is right there. The zb-equipment wins on specification depth: the model code and the humidity range give you more to reference when building a control panel or filling out documentation.
Product Notes
marddpair VFD
The marddpair drive is the price-focused option in this comparison and it doesn't miss the basics. It uses an MPN (AMZ1095683) rather than a model name, which is fine if your documentation is MPN-based. The electrical spec list includes a clear per-phase current value, and the country-of-origin line reads United States. For a lower-list-price unit, that's a solid set of reference points. The trade-off is that the attribute set is built around electrical parameters; if you need a model code for a nameplate, the MPN is your identifier. For a no-frills installation, that's enough.
zb-equipment VFD
The zb-equipment drive carries the GEGS-753 model code, which is easier to reference on a bill of materials or panel drawing than an MPN. It also lists a humidity range of 0-95% RH without dew, giving you an environmental operating window. The drive matches the marddpair on core controls, so the higher listed price buys documentation depth rather than a different control method. In the attribute set, the current reference appears in the description as 34A rather than in a per-phase amperage field. That makes it the better choice when a clean reference tag matters more than the price difference.
Final Choice by Use Case
For a straightforward retrofit on a single-phase feed where price leads the decision, the marddpair at USD 119.39 is the practical default. It gives you the same control approach and input flexibility with a lower list price. For an install where a model name, GTIN, and humidity spec matter-say, a labeled control cabinet or a documented shop upgrade-the zb-equipment at USD 160.90 is the one to specify. Both drives are designed for the same motor-size class; the choice is between saving on the front end and having a more complete reference tag.
