Two of these 840W power modules are included with M3-CLOS-ENCL-B and M3-SPINE-ENCL-B enclosures. The enclosures will accommodate up to four of these power modules, which operate in an auto-parallel mode and can be individually hot-swapped. One operating power module is sufficient to supply the maximum power an enclosure may require, but two are provided for redundancy and power derating.

Specifications

Power output: +12V @ 70A (840W) maximum with auto-parallel capability.

Power input: 100-240 V~, 12A maximum, 50 Hz / 60 Hz. The power factor at full load is typically 0.98, but at typical load is ~0.90.

Efficiency: 82% minimum at full load and "high line" (maximal input voltage, a worst case).

Monitoring functions: The power modules plug into a circuit board at the base of the enclosure. A microcontroller on this circuit board monitors and reports on the internal low-speed network "AC good" and "DC good" status information from each power supply.

LEDs: Each power supply has a red/green bicolor LED to verify the presence of input and output power (green) or indicate a fault (red).

Physical characteristics: Dimensions: width: 3.30 inches (83.8mm), case height: 1.58 inches (40.2mm), depth not including handle and circuit-board connector: 11 inches (279.4mm). Weight: 3.4 pounds (1.55 kg).

Environmental limits: Operating: Temperature -10C to +50C up to 10,000 foot altitude. Relative humidity 20% to 90% non-condensing. Storage: Temperature -40C to +85C.

Manufacturer and model number: Astec DS850-3.

Regulatory Approvals: When properly installed in Myricom M3-CLOS-ENCL-B or M3-SPINE-ENCL-B enclosures, the power module is fully compliant with EN55024 (1998), EN55022 Class A (1998), VCCI Class A (May 1999), FCC Part 15 Subpart B Class A, CISPR 22/85 Class A, ICES-003 Class A (ANSI C63.4 1992), and AS/NZS 3548 Class A (w/A1 & A2 1997). (View the EMC test report.) These power modules are RoHS and lead-free compliant.
