Dawn PSC-6265

Conduction Cooled, -40 to +85°C Operating Range

Manufacturer: Dawn VME
Dawn PSC-6265

Dawn’s VITA 62 compliant 6U PSC-6265 can operate continuously in diverse environments over a wide range of temperatures at high power levels. The standard model is conduction to wedge lock cooled with an operating temperature range of -40C to +85C and a non-operating range of -55C to +105C.

The PSC-6265 operates continuously at a power level of 580 watts. For systems that require higher power levels, up to three supplies may be operated in parallel.

Fault monitoring and control circuits protect the system from over-voltage, over-current, and over-temperature conditions.

Power supply operational or fault status is displayed using coloured LEDs on the front panel.
