N-02751-PFC-240-0000 - Powerstax

Powerstax continues to lead the power density race with its new small, high efficiency open frame N-0275 Series AC-DC power supplies. The N-0275 Series provides up to 90% efficiency and the very small footprint reduces wasted power. The unique design reduces energy consumption and generates less waste heat. It requires little forced air cooling, decreases AC loads and increases reliability and economy of operation. With an overall height of 1.5″ and a 3″ x 5″ footprint, the N-0275 Series boasts a power density over 12 watts per cubic inch. It is ideally suited for OEMs using the industry standard 1U chassis. An optional I2C digital communications interface is also provided to allow up to four N-0275 to communicate over the same bus using the I2C protocol. This interface allows routine remote control of the main outputs and the 12V fans. It can also notify the host if a fan fails (lost tachometer pulses). The host can also query the microcontroller for its output voltage and current plus the ambient and transformer temperatures.
