Sunnyvale, Calif. XP Power announced availability of the SDS150, a convection-cooled power supply that is suited for IT and industrial applications where space is at a premium and there are no internal fans. Both open-frameand U-channel models can be used in 1U customer applications. The open frame model, 76 x 127 x 36 mm, offers power density of 6.9 watts per cubic inch and the U-channel, 81 x 127 x 39 mm, density is 6.1 watts per cubic inch. The unit has efficiency of up to 90% and has a universal input of 90-264 VAC. There are 8 single-output voltage versions ranging from 9 VDC to 48 VDC. No minimum load is required for the unit to start up and maintain stated specifications.
The SDS150 operates at full power from 0°C to +50°C and up to +70°C with derating. The unit benefits from over-voltage, over-current and short circuit protection in order to safeguard connected equipment. An optional power-fail detect signal can alert attached hardware of any impending power failure. Unit efficiency is improved by the use of synchronous rectification. This technique uses power MOSFETs in place of traditional diodes as active switches. Such controlled switches act as rectifiers and results in lower losses in the output stage. The power supply is approved to UL60950-1 & EN60950-1 safety standards and meets EN55022 level B conducted emissions standards.
Pricing: $92.30 each in 1,000-piece quantities
