Tracewell Systems, Inc. Introduces The DH-242 Power Supply for VXI Applications
COLUMBUS, OH, May 19, 2004—Tracewell Systems, Inc. announces the DH-242 power supply, which is designed to provide power for VXI applications and features eight independently regulated outputs that will deliver full rated current to meet these power requirements. Maximum output is 1488 Watts at 45°C with 400 LFM of air and typical efficiency is 90%. A special 12VDC output is provided to operate system fans. Each output is independently thermally protected, and multiple supplies can be combined in a system with full load sharing.

In keeping with the best of modern distributed power architectures, the power supply operates from a 48VDC system bus, which is especially useful in high power applications. The unit’s high efficiency makes it ideal for portable or battery-powered applications, or any situation with a tight power budget; it also allows it to be cooled entirely by system air.

The DH-242 plugs into the front of the equipment panel, is the size of a standard VXI card at 6U high by 7hp wide, and weighs 6 pounds.


The power supply features LED status indicators on the front panel for INPUT OK, OUTPUT OK and POWER SUPPLY FAIL. RS-485 communications allow the status, internal and remote temperature sensors, external fan speed and output voltages of the power supply to be remotely monitored. Also standard is an open-collector SYSTEM RESET output (which can also function as a POWER GOOD signal).

Available options
Optional enable circuitry allows the power supply to be remotely enabled. Half duplex communication RS-485 communication is standard, and full duplex is available as an option. In addition, special enhancements are available to allow the unit to be used in PXI systems.

Rugged Design
The power supply has been tested in a system to 50 Gs random vibration, and has been HALT tested at 1kW load from –30 to +80ºC.

Price and Availability
Pricing for the DH-242 VXI Power Supply starts at $2670 (min quantity 10 units), and availability is 8-10 weeks ARO.
