Low profile 400W ac-dc switcher fits in 1U high apparatus
( 01 Nov 2006 )
The SMM400 series from XP Power is a family of 400W ac-dc switching power supplies that enable more power to be delivered in an industry-standard 1U high enclosure.
Most 1U units are limited to around 250W but this power supply, which has power densities of up to 6.25W per cubic inch, meets demand for higher power within a given space. The low profile units come in 24 standard models—19 singleoutput, and 5 dual-output versions — and carry agency approvals for communications, IT, industrial, and medical applications.
The SMM400 has a universal 90 to 264VAC input with a choice of output voltages from 3 to 48VDC. The unit is available in either U-channel or enclosed formats, with integral cooling. Over-current, over-voltage, and over-temperature protection are included. Safety approvals include UL60950 and EN60950 for industrial and IT applications, and UL60601-1 and EN60601-1 for medical systems. The power supplies meet all major international EMC requirements.
