Compact front-end supply takes MCU comms onboard

The FNP300 Series of 300W front-end power supplies feature a compact footprint, built-in microcontroller and wide-range input operation.

The FNP300 Series of AC/DC 300W front-end power supplies feature a compact footprint, built-in microcontroller and wide-range input operation (85 to 264V AC) with the capability to ride through short pulses up to 300V AC.

FNP300 models are offered with 12, 24, or 48V DC outputs rated at 25, 12.5 and 6.25A, respectively.

All models also provide a 12V at 0.7A standby output for powering serial communication interfaces and small fans.

The onboard microcontroller facilitates I2C-compatible bidirectional communications with the host system including power fail, output good, thermal shutdown, and inhibit.

In addition, the microcontroller controls the fan speed to increase MTBF and reduce acoustic noise.

Power factor correction, hot-swap capability, and N+1 redundancy with ORing-diode current sharing are standard features.

Protection features include overvoltage, overcurrent, and overtemperature.

Overall dimensions, including an integral fan, IEC connector, and a blind-mate output connector are 41.9 x 101.6 x 215.9mm.

Agency approvals include UL60950, CSA60950 (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.
