We are offering two phase to three phase converters : three-phase power is not always available. To keep cost down, often only one phase is fed from a street transformer to a house. There are two options, if an industrial machine has to be connected. Installation cost for three-phase power lines may be high. Single to three- phase converters are another good solution. Phase convert two phase 415v into three phase 380v, 400v or 415v. Booster: standard converters for multi-motor applications. Motors will produce 100% nameplate torque continuously, up to 200% during start-up or excessive loads. One output socket.Booster e: high performance converters for all single and multi-motor applications and all hard-start conditions. Motors will produce 100% of nameplate torque continuously and up to 600% during motor start-ups and excessive loads. Two output sockets. For all motor start-stop, reverse, hard-start conditions (metal lathes, wheel balancers, irrigation pumps, conveyors, elevators, refrigeration systems, compressors, deep submersible pumps, hydraulic systems.). Input voltage is 380v, output voltage is 3x 380-415v.
