3 Phase Rotary Converters

Locally Designed and Built

Rotary Converters for supporting multiple 3 phase machines or motors from Single Phase power.
Output Power Classes: 4 kW, 8 kW, 12 kW and up on request
Units are engineered for continuous 100% duty cycle at full load plus over-current states for motor starts under load.
Input Voltage options cover all variations found in Australia including single phase 240V, single phase 480V and 2 out of 3 phase supply at 415V.  Special customised solutions are also offered for off-grid applications.
Units are equipped with internationally proven Eurotech power electronics to suit the customer application.  Whilst semi-symmetrical output is excellent for most equipment, fully symmetrical output Voltage is designed for critical applications such as VFDs or CNC machines.
The unit’s innovative cooling design features bottom to top passive cooling to optimise long term reliability, a key design principle applied throughout to achieve extreme service life.
