3U Power Supply

February 1, 2013

Dawn VME Products (Fremont, CA) offers the PSC-6236 universal AC-input, VITA-62-compliant, 6-channel 3U OpenVPX power supply, with up to 400 watts output for air or conductioncooled systems. The power supply defines connector configuration, power generation requirements, utility, functionality, and form factor needs for power modules mating to a VPX backplane power supply slot. Input range is 85-264 VAC, 47-400 Hz.

The PSC-6236 offers current sharing with up to four power supplies for outputs of 12V, 5V, and 3.3V. The power supply is designed to be compliant with MIL-STD- 461, MIL-STD-704F, and MIL-STD-810F. Dawn's proprietary embedded RuSH™ Rugged System Health Monitor technology actively measures voltage, current, and temperature on each rail.

The PSC-6236 is interfaced to the Intelligent Platform Management Bus (IPMB), providing an I2C communication link with system cards. Onboard microprocessor and firmware offer real-time over voltage, over current, and over temperature protective control, with factory programmable power sequencing and shutdown for all voltage rails. Firmware enables additional PSC-6236 features, including customer-specified monitoring windows for power sequencing, special alerts, alarms, and status reports. An optional 3-axis accelerometer records and time-stamps shock, vibration, and other critical events. The PSC-6236 front I/O panel includes an LED status indicator, a USB port for field firmware upgrades, and VBAT battery access for support of the VPX memory backup power bus.
