Maharashtra-based perfect electronics offers has introduced a 3-phase to single phase changer kit. There are some technical features of this phase changer include: the 3 phases of the mains go to the input of this circuit and the output is of single phase. If any one or two phases fail or are switched off, then the remaining phase will go to the output. Perfect electronics also supplies technology transfer at attractive rate, which includes circuit diagram, details of pcb and films of pcb. This phase changer finds its applications inthis device is used in lodges and hotels where three phases are available. This phase changer also finds its applications in it is also used in ups systems. Following are some of the electrical features of this phase changer which include: power of the unit depends on contact rating of the relays used in the circuit. This kit includes 3 pcb mounted relays of contact rating of 2 amperes. The company offers technology transfer at attractive rate, which includes circuit diagram, details of pcb and films of pcb.
