Murata Power Solutions (Mansfield, MA) has introduced three new PICMG 2.11-compliant CompactPCI high reliability power supplies. The cPCI-A-3U-300C, cPCIA-3U 200C AC/DC power supplies, and the cPCI-D-3U-300C DC/DC power supply are all housed in industry standard 3Ux8HP enclosures and are capable of delivering continuous full power across their -5°C to +55°C operating temperature range with airflows as low as 250lfm. All three models have efficiency levels in excess of 80%, are hot-swap capable, and require no minimum load. Power density is 8.5W/cu.in.
The cPCI-A-3U-300C (300W) and cPCI-A-3U-200C (200W) have a wide input voltage range of between 90VAC and 264VAC; the cPCI-D-3U-300C (300W) accepts 36 to 72VDC. Wide-ranging input voltages, safety agency approvals to UL60950 and EN60950, and EMI compliance to Class B FCC and EN55022 standards make the power supplies ideal for use in globally deployed systems in applications such as networking and telecommunications, industrial, test and measurement, and medical. All offer the standard CompactPCI output voltages of 3.3V, 5V, 12V and -12V. The use of two converters operating in parallel for the 3.3V and 5V outputs enables maximum current draw on the two outputs simultaneously.
