Murata power supplies

Murata has introduced three PICMG 2.11-compliant CompactPCI power supplies.

The cPCI-A-3U-300C, cPCI-A-3U 200C AC/DC and the cPCI-D-3U-300C DC/DC are all housed in standard 3U x 8 HP enclosures and can deliver continuous full power across their -5 to +55 °C operating temperature range with airflows of 250 lfm.

All models have efficiency levels of more than 80%, are hot-swap capable and require no minimum load.

The cPCI-A-3U-300C (300 W) and cPCI-A-3U-200C (200 W) have a wide input voltage of between 90 DC and 264 DC. The cPCI-D-3U-300C (300 W) accepts 36 to 72 VDC.

Wide-ranging input voltages combined with safety agency approvals to UL60950 and EN60950, EMI compliance to class B FCC and EN55022 standards, make the supplies suitable for use in global systems such as networking and telecoms, industrial, test and measurement and medical.

All offer the standard CompactPCI output voltages of 3.3, 5, 12 and -12. The use of two converters operating in parallel for the 3.3 and 5 V outputs enables maximum current draw on the two outputs simultaneously.

Additional features include active power factor correction to EN61000-3-2, remote sense compensation, unit enable control, output inhibit control, output fault signal and thermal warning signal.

LEDs provide visual indication of input power presence and output fault detection.
