Buenas tardes. A quien corresponda les hago llegar esta mi petición compré el variador de potencia de 3cv. Pero me equivoqué comprando de 220 voltios y necesito de 380 voltios para reemplazar el anterior, El anterior de 220 v está completamente nuevo NUNCA SE INSTALO. Será que porfavor me lo pueden cambiar pagando yo la diferencia de precios. Muchas gracias

L-am conectat la o pompa submersibila (20m adancime) monofazata de 220V si 1.1 kW. Am conectat pompa la iesirile U si W pastrand condensatorul. Pornirea si oprirea pompei se face prin presostat (3bar start, 4 bar stop) conectat la X1/X3 iar reglajul PID a presiunii printr-un traductor de presiune 0-10 bar, 4-20mA conectat la AI2 (parametrii au fost configurati conform exemplului din manualul de operare). S-a configurat domeniul de lucru al pompei intre 35-50Hz (35Hz fiind o turatie suficienta a pompei astfel incat atunci cand se inchid toti consumatorii pompa sa poata ridica presiunea pana la conditia de stop 4 bar). Concluzii: convertizorul suporta motoare monofozate de 220Vac (prin setarea unui parametru), pornirea si oprirea pompei nu se mai face cu socuri mecanice si nici nu se mai sting becurile in casa la pornire (soft start). Regulatorul PID functioneaza precis, in functie de setari. N-am observat anomalii pe parcursul a cca 2 saptamani. Optiunile pe care le are, usurinta in al parametriza il ridica peste nivelul unor convertizoare din gama entry level al majoriratii brandurilor industriale (raportat si la pret). Daca se va dovedi si fiabil in timp atunci e un best buy. Nota 10 si pt furnizor, l-am primit in 3 zile.

I am running mine at 241 volts. Since this is Chinese and designed for 220 volts I was a bit nervous but it seems to handle the higher US voltage at 60 Hertz just fine. The instructions were written by someone who doesn't know English but I'm okay with that.

Lo compre para un elevador de coches trifásico y funcionó a la primera!! la verdad que estaba un poco escéptico, pero sin problemas, llegó rápido y fácil de instalar
