Dawn VME Products Announces PSC-6234 VITA 62 Compliant 3U VPX Power Supply

400 watt 6 channel plug-in or bulkhead mounted power supply for air or conduction cooled OpenVPX systems

FREMONT, Calif. - Dawn VME Products, a leading designer and manufacturer of high performance and reliable embedded packaging technology products based on the VITATM and PICMG® architectures, announces its PSC-6234 VITA 62 compliant 6 channel 3U VPX power supply with VITA 62 power connector pin-out and full OpenVPX support.

Dawn's PSC-6234 power supply is designed for mission critical applications to operate over a wide range of temperatures at high power levels. Plug-in or bulkhead mounted models are available for air cooled, conduction to bulkhead cooled, and conduction to wedge lock cooled applications and configurations.

Its true 6 channel design provides up to 400 watts output on a 1 inch pitch and is extended shock and vibration compliant per MIL-STD-810F. Custom power capacity and voltage input range configurations are available. The PSC-6234 is current share compatible with additional PSC-6234 units.

The PSC-6234 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.

Dawn's embedded RuSHTM Rugged System Health Monitor technology actively measures voltage, current and temperature on each PSC-6234 rail for intelligent monitoring and control of critical VPX power supply performance parameters.

The RuSH(TM) monitor is interfaced into the OpenVPX management plane, providing an I2C communication link with system cards. Onboard RuSHTM provides real-time over voltage, over current and over temperature protective control, with factory programmable power sequencing and shutdown for all voltage rails.

Custom RuSHTM firmware enables additional PSC-6234 measurement sensing for humidity and customer specified monitoring windows for power sequencing, special alerts, alarms, status reports and other monitoring and control factors. An optional 3-axis accelerometer records and time stamps shock and vibration events.

Dawn offers application-specific VITA 62 compliant power supply design, manufacturing and production through modifications to the PSC-6234 platform, and can incorporate requirements into a customized power management solution for prototyping and development.

"The PSC-6234 provides the mission critical market a true 6 channel 3U VPX power supply with VITA 62 compliant connector pin-out," says Barry Burnsides, Dawn VME Products Founder and CEO. "Embedded with RuSHTM technology monitoring and control, the highly configurable and current share compatible PSC-6234 delivers up to 400 watts each of field-deployed reliable output."
