400 W switcher PSU fits in 1U high apparatus
23 August 2006, Power Electronics / Power Management
XP Power has developed a family of 400 W AC/DC switching power supplies that it says enables more power to be delivered in an industry-standard 1U high enclosure. Most 1U units are limited to around 250 W but the new SMM400 series power supplies that have power densities of up to 380 mW/cm³, meets demand for higher power within a given space. The low profile units come in 24 standard models - 19 single-output and five dual-output versions - and carry agency approvals for communications, IT, industrial and medical applications.
The SMM400 has a universal 90 to 264 V a.c. input with a choice of output voltages from 3 V to 48 V d.c. The primary output is user adjustable by ±5%. It has remote sense, power-good and remote on/off functions built in, with a current share function and AC fail signal offered as options. The unit is available in either U-channel or enclosed formats, with integral cooling. Over-current, over-voltage and over-temperature protection are included.
Screw terminals are standard and IEC or Molex input connectors, and Molex output connectors, are available as options. The integral fan version provides the 23 CFM cooling needed for full power operation and the units are rated at 250 W with only convection cooling. The SMM400 operates in ambient temperatures from 0 to 50°C at full power with derating to 70°C.
The SMM measures 228,9 x 127 x 40,6 mm with fan and cover, excluding the input screw terminal block, or 203,3 mm long for the U-channel. |
