basic information
It is ideal for energy recovery systems such as solar power generation, small wind power generation with storage systems, and motors. ● By utilizing the latest digital control technology, it achieves a maximum efficiency of over 94% in both directions, despite being an insulated type with a high boost and buck ratio of 320V/48V. Even at maximum rated output, it maintains a high efficiency of over 92%. ● The switching of the power conversion direction can be done without stopping the converter. The switching time between boost and buck is only 15 msec (typ.). It is possible to minimize fluctuations in the power bus during the switching of the power conversion direction. ● In addition to switching the power conversion direction externally using RS485, EZA can autonomously control the switching of the power conversion direction based on pre-set voltage conditions while monitoring the voltage on the high side or low side.
