Emerson Network Power has introduced the DS460S-3 bulk front end ac-dc power supply which achieves a typical conversion efficiency of 92% at 50% full load.

With a 1U x 2U form factor the 460W rated power supply generates a main payload output of 12Vdc and an auxiliary output of 12Vdc for powering standby circuitry.

It features a 90 to 264Vac input voltage range and employs active power factor correction to minimise input harmonic current distortion and ensure compliance with the international EN61000-3-2 standard, with a power factor of 0.99 typical.

Digitally programmable, the DS460S-3 is equipped with an I2C interface available with industry-standard PMBus communications protocol.
