text: <s>[INST] allen-bradely 1332 vfd 1 to 3ph Summary: can the vfd output 3ph out of 1ph?Hi, I own an allen-brdley 1332 CAN variable frequency drive. The unit is rated 380VAC and 5hp. It is main purpose is to change the frequency of a three phase input. I read in some forums though, that all vfd's can output 3 phases pout of one, with only a drawback of fallen horsepower. I also see in the manual of the 1332, that specifically the 230VAC units can output 3phases out of one. My purpose is, since i do not have access to 3 phase power in my current lab, to create it out of the 230VAC. I understand that the 1332 cannot step up the voltage given in it, so my though would be to use a transformer to output 380VAC. The motor i want to drive is 1,1hp. Are these units known to work at such a level? Would it be safe for the unit to try to input 380VAC one phase to test the output or may i damage the unit? any help appreciated [/INST] What manual I could find on line does not reference 1332 drives rated at 380VAC. They reference 230, 460, and 575V drives. The manual I found does say THOSE 1332 drives can take single-phase input. That said, I would not simply presume all 1332 drives can take single-phase input. Contact Rockwell Technical Support and see if they better documentation than I've been able to find on line; this one has a publication date of 1987. \\n </s>
