Power supplies made for CompactPCI systems

Elma Electronic has extended its support for complete cPCI enclosures and sub-racks, by launching the first of a range of low cost, high reliability AC/DC and DC/DC power supplies.

All models use a high efficiency synchronous rectification design, which provides parallel 5 and 3.3V convertors, ensuring that designers can achieve both full power and the rated 400kh MTBF (500kh for DC/DC) under a wide variety of load conditions.

The units are PICMG 2.11 compliant, and offer hot-swap capabilities using the standard 47-pin Positronic connector.

AC or DC input is available in either 200W 3U or 400W 6U versions, operating from -10 to +55C with no derating.

The DC/DC units are available with 48V input to suit central office applications, and the AC units offer universal input voltage operation (85-264V at 47-63Hz).

Prototype quantities of all models are available from stock, with larger volumes available within 4 weeks.

Overcurrent, overvoltage, overtemperature and short circuit protection are all standard, with protected remote sensing of 5 and 3.3V lines.

In addition to active power factor correction and input fusing, filtering of both common mode and differential ripple meets FCC68 part 15 and EN55022 class B.

Surge and lightning ratings meet IEC1000, and worldwide safety approvals include UL, CSA, TUV and CE.

All units include hot-swap and current sharing features to suit N+1 redundant systems, and have no minimum load requirements.

In addition to front panel indicator LEDs, and standard PICMG 2.11 status, inhibit and deg signals, an intelligent I2C bus is provided to provide comprehensive remote status monitoring and control.
