Dawn VME Products announces the PSC-6238 VITA 62-compliant power supply that features up to 800-W 3U OpenVPX for conduction-cooled systems. The power supply operates in a military environment over a wide range of temperatures at high power levels. It features extended shock and vibration compliance per MIL-STD-810F and features an onboard real-time clock with switchable Battleshort and nuclear event detect (NED) functions.
The power supply is a wedge-lock conduction-cooled module on a 1-in. pitch with an operating temperature from –40°C to 85°C at the wedge-lock edge. It also features a six-channel supply that provides full Open VPX support and is current-/load-share-compatible with up to four PSC-6238 units. The front I/O panel includes a three-color LED status indicator, VBAT battery access, and a USB port for status display, access menu control, and firmware upgrade.
The embedded rugged system health monitor technology provides for intelligent monitoring and control of critical system performance parameters, including voltage, current, temperature, and control of power sequencing and shutdown of all voltage rails. Custom firmware is available that enables additional features, such as monitoring humidity, shock/vibration events, or customer-specified monitoring windows, power sequencing, alerts, alarms, status and control, and event logging.
