Kontron CPS3-SVE-250AC - 3U 24 HP Wide-Range PSU, 85 to 264 VAC, 250 W

Cable to Backplane, -40 to +70°C Operating Range

Kontron CPS3-SVE-250AC - 3U 24HP PSU, 85-264 VAC, 250W
Key Features
250W AC PSU for CompactPCI® Serial
3U, 24HP board
Input voltage range of 85 to 264 VAC
Output power 250W (derating for < 50°C)
Holdup time 16ms minimum
Cable to backplane (included)
-25 to +70°C operating range


For flexible, reliable, and energy saving usage

The CPS3-SVE-250AC provides all basic features to run a CompactPCI® Serial system. Several protection and regulation options, basic monitoring functions, and its hold-up time make the power supply a reliable system component. It provides +12V output and +5V standby, and therefore is not intended for use in classic CompactPCI® systems. The product meets EMI EN55022 Class B, a must for many applications. High effi ciency and low standby input power is energy-saving and makes system cooling easier. Its wide input range of 85-264 VAC, and its operating temperature range of -25°C up to 70°C, even fanless with convection cooling, show how flexibly this power supply can be deployed.

Whenever cost saving is more important

Whenever some advanced features like hot-plug, redundancy, and PMBUS support are not required, and cost saving is more important, CPS-SVE-250AC is the right choice for CompactPCI® Serial systems.

Integrated part of a CPCI Serial card cage

The power supply is horizontally mounted into a cartridge to enable convection cooling. A guide rail and a backplane connection cable is included. The article is non-pluggable and comes as integrated part of a standard card cage. For integration into an alternative, custom selected enclosure and backplane, the power supply shall be combined with Kontron’s "AC Input Kit and Integration Service" CP-MKIT-AC-IN.
