CPS3-SVE-S300AC is a 300 Watt power supply is flexible for many operational conditions. It has a wide input range of 90-264 VAC, and operates under extended temperature from -40°C to +70°C at full rating. It provides 12V output and 5V standby as defined for CompactPCI® Serial.
CPS3-SVE-S300AC provides the full feature set as recommended by the CompactPCI® Serial community, including the rear connector. Redundancy and hot-plug, several protection and regulation features, advanced monitoring functions via I²C/PMBUS as well as its hold-up time make the power supply a reliable backbone of every CompactPCI® Serial platform.
Integration by hot-plug from the frontside to a backplane connector - no cabling, no power down of redundant systems - this makes the application more reliable and maintenance in the field an easy matter.
