300W 3U DC CompactPCI supply targets rail and trackside
The CPCI-3U-DC-300W RL is specifically designed to meet the requirements of EN50155 and takes a DC input in the range 66-160Vdc to provide four outputs; +5VDC at 30A, +3.3V at 40A, +12V at 5A and -12V at 0.5A. The maximum total output is 300W with forced air cooling and the power supply is fully protected against output overload, short circuit and over temperature with automatic recovery on removal of overload condition. The operating temperature range is -40 to +70°C at full load with forced air.
For system integrators full monitoring command and control is available including remote sense on the two main outputs with maximum voltage compensation for cable losses 200mV. Remote inhibit and enable controls and a power fail signal are fitted as standard. LED indicators show power good and output failure. Current share is available on outputs 1 and 2 and the power supply is designed for hot-swap operation and has an optional I2C interface.
The supply meets the UL 60950, EN 60950, EN 61000-4-2, standards as well as EN55022/CISPR22 Class B with an external TBD line filter and it is fully compliant to PICMG 2.11 CompactPCI Specification. It has dimensions of 128.7mm x 40.6mm x 162.5mm (5.07”H X 1.60”W X 6.40”D) and weighs 850g.
This is part of a range of CompactPCI power supplies used by major OEMS for instrumentation and industrial systems which can also be ruggedized and conformally coated for MIL applications. Available in both 3U (100mm by 160 mm) and 6U (160mm by 233 mm) versions, the range includes both AC and DC inputs. Output power is available from 200W up to the market leading 6UAC input model with a 650W output. 6U 24V and 48V input models are also available.
