Camarillo, Calif. - Power-One's FNP300 Series of 300-watt AC/DC front-end power supplies feature a built-in microcontroller, which facilitates I2C-compatible bidirectional communications with the host system to signal such conditions as power fail and thermal shutdown, as well as to control fan speed.
The FNP300, working from an 85-264 VAC input, provides 12 at up to 25 amps, 24 volts at 12.5 amps, or 48 volts at 6.25 amps. All models also provide a standby output (12 volts at 700 mA) for powering serial communication interfaces and small fans.
Power-factor-correction, hot-swap capability, and N+1 redundancy with ORing-diodes for current sharing are standard features. Protection features include over-voltage, over-current, and over-temperature. These supplies, including an integral fan, IEC connector, and a blind-mate output connector, measure 1.65 by 4.0 by 8.5 inches.
Agency approvals include UL 60950, CSA 60950 (UL/cUL), EN60950 (TUV). The CCC mark is pending. CB reports are available by request. Pricing for the FNP300 series is $325 each in quantities of 100. Evaluation units are usually available from stock. Production quantities are typically available in eight to ten weeks.
