Front-end supply meets gold standard

The DS460S-3 bulk front-end ac/dc power supply suits applications that use distributed-power architectures, such as computing, storage, networking, datacom, and test and measurement systems. It achieves 92% typical conversion efficiency at 50% load, meeting the Climate Savers Computing Gold standard. With a 1U x 2U form factor and 7.75-in. length, it targets length-limited applications and midplane design configurations.

Rated at 460 W, the front-end power supply generates a main output of 12 Vdc and an auxiliary output of 12 Vdc for powering standby circuitry. It features a 90 to 264-Vac input-voltage range and employs active power factor correction to minimize 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 supply is equipped with an I2 C interface available with industry-standard PMBus communications protocol. ($189 ea/prod qty – available now.)
