3U, 8HP board
Input voltage range of 90 to 264 VAC
Output power 300 W (requires fans)
Holdup time 20ms minimum
SSI-type rear connector
-40 to +70°C operating range


Flexible usage

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.

Advanced feature set for high system reliability

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.

Easy system integration and field maintenance

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.

OtherOverload Protection: The feature will reduce the output voltage to a safe dissipation level when the output power rating exceeds 125% of maximum rated power. The unit will automatically return to regulation upon removal of the overload.
Overvoltage Protection: Set at 115% to 135%. Latching method (recycle AC to restart)
Short-circuit Protection: The units will withstand a continuous short without damage, it will automatically return to regulation upon removal of the short
Thermal Protection: Yes, built in thermal sensor to protect abnormal temperature conditions
Remote Sensing: (R2/E3) On 12V output only
PS_ON (F3): Digital input: A logic low enables the main output, a low shall not source > 1 mA
Enable (R6:) Digital input: when driven high, main output is disabled, when low, main output state is as controlled by PS_ON
FAL/PWR_FAIL (U2): Digital output, Open Collector, driven high when outputs are in regulation. It will go low minimum 1 ms prior to output going out of regulation
DEG (U5): Digital output, Open Collector, temperature warning signal. A TBD temperature will change signal state from Hi to Low or Low to Hi
(programmable preferences)
PS Present (H3): Digital Output, pulled low via 100 Ohm resistor
I²C / PMBUS: Monitors temperature, output voltage, and output current; connects to a serial NVRAM which is programmed with serial number, PMBUS
Standard to allow monitoring of overall operation of power supply
LED Indicators: Bicolor LED: Green LED: all outputs operating within specifi cations, Red LED: power supply out of specifi cation
