Features: 1. Isolated output transformer,suit for any unbalance loads; 2. Every single phase can be used independently; 3. EMC compatible,Low noise; 4. Thoroughly proven advanced SPWM and IGBT technology; 5. Galvanically isolated,low harmonic distortion; 6. Pure Sine wave,sinusoidal output; 7. Variable frequency and voltage; 8. Display real-time data: voltage,current, frequency and power.
ERF60W is designed to change conventional 50 Hz or 60 Hz electrical energy to the needs of the shipboard power in an indoors type of enclosure for installation in a substation or power distribution room. It can also be the shore to ship power converters in an all-weather outdoor enclosure for installing on the dockside or mooring berth.
It integrates IGBT made by Mitsubishi, Siemens and Infineon with PWM switching technology, and combines micro controller (digital signal control) design for quicker response and higher reliability. ERF60W is widely used in shipyard, ship manufacturing and repair plant, docks and other powered ship occasion.
