Emerson Network Power in Carlsbad, Calif., is introducing the DS460S-3 bulk front-end AC-DC power supply for applications that use distributed power architectures, such as computers, data storage, networking, data communications, as well as test and measurement. The DS460S-3 power supply is 92 percent at 50 percent full load. With a 1U-by-2U form factor and measuring 7.75 inches long, the DS460S-3 is for length-limited applications and mid-plane design configurations and, at a height of 1.6 inches, is for use in 1U rack-mounting equipment. Rated at 460 watts, the DS460S-3 power supply generates a main payload output of 12 volts DC and an auxiliary output of 12 volts DC for powering standby circuitry. It features an input voltage of 90 to 264 volts AC and uses active power factor correction to minimize input harmonic current distortion and to comply 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. The DS460S-3 also features a built-in, low-noise smart fan and holds safety certifications from UL/cUL, NEMKO, CB, and CE.
