V2 Power Module

The V2 AC/DC power module is a MCU/DSP controlled, highly efficient front-end power supply. It incorporates resonantsoft- switching technology to reduce component stresses, providing increased system reliability and very high efficiency. The PFC stage is digitally controlled using a state-of-the-art digital signal processing algorithm to guarantee best efficiency and unity power factor over a wide operating range. The main DC/DC stage (12.6V/3300W) uses soft switching resonant techniques in conjunction with synchronous rectification. An active OR-ing device on the output ensures no reverse load current and renders the supply ideally suited for operation in redundant power systems. The auxiliary DC/DC stage (54VDC/300W) uses a soft switching resonant topology is also protected with an active OR-ing device for maximum reliability. The DC/DC converter from the battery input (3600W) provides power to the internal high voltage bus and allows the outputs to continue up to 90s during AC outage. A battery charger stage (52.5V/270W) allows to re-charge the battery backup unit (BBU). Status information is provided with a front-panel LED. The RS485 bus allows full monitoring of the supply, including input and output voltage, current, power, and internal temperatures. The supply is fan cooled and ideally suited for integration with a matching airflow path. Cooling is managed by a fan controlled by the MCU. The fan speed is adjusted automatically depending on the supply temperature.
