Power Sources Unlimited, Inc. presents the TSP Series, a new generation of high performance DIN-rail power supplies with innovative and powerful features. Featuring a rugged metal case, complete with shock and vibration proof construction, the TSP Series is designed to provide reliable power even in the most difficult factory conditions.
Excellent electrical specifications and high immunity against electrical
disturbances makes the TSP series product the best choice to power
sensitive loads in industrial process controls, machine tools or other
demanding applications. A high power reserve guarantees a reliable
start-up of loads with high inrush currents such as motors.

14 standard models are available with tightly regulated, adjustable output
voltages of 12, 24 and 48VDC, with ratings up to 25A. The power supplies
are specified for industrial operating temperatures from -25°C to +70°C
with convection cooling and also provide thermal overload protection.
Remote on/off is standard.

The TSP Series offers three add-on Function Modules which offer battery
back-up, output buffering or true redundant operation in system
applications.

The TSP Series has worldwide safety approvals, including an optional ATEX
certification for Class l, Div.2 applications in hazardous locations.
A recent expansion the product family introduced the TSP-WR Series, which
feature an ultra wide input voltage range of 85 to 550VAC, enabling the
TSP-WR models to be used in almost any single or 3-phase power network in
the world.

Pricing starts at $77.00 for 100 piece quantities. Download full

Sunnyvale, California – March 26, 2007 – Magic Power Technology Inc. introduces the new 150-watt MPD-815H 24V DC input to ATX output power converter. The MPD-815H is designed to be convection cooling, is RoHS compliant, and fits within 1U height constraints. It is an idea power source for a wide variety of DC input industrial applications and embedded devices.

The MPD-815H provides U-channel chassis for efficient heat conduction. This design not only increases the reliability and the performance but also reduces the dust into the system and has no noise to influence the environment. It is compliant with UL 60950, operates over a wide 18 to 36 VDC input range, and provides short-circuit, over voltage and thermal protection. This MPD-815H offers competitive densities without performance deratings from 0 to 50°C.

Other features include terminal block design for both input and output, and top cover is optional. Samples for MPD-815H are available now.

Powerstax plc, the Farnborough UK based manufacturer of high efficiency DC:DC converters and application rich power solutions have been selected to supply a turnkey power solution to EcoLEDLighting, market leaders in LED lighting systems. EcoLEDLighting has recently launched its new Part L Compliant, fully dimmable MR16 lamp replacements, which reduce heat output by 80% and use 75% less energy. To enable the company to develop prototypes into production designs, EcoLEDLighting went looking for a power supply company that was able to fulfil the specific requirements that were essential for this new LED lighting technology. Powerstax provided one of their trademark added value systems comprised of a high efficiency, ultra-compact 10W AC to DC, universal input voltage, encapsulated power supply mounted on a PCB with a variable LED driver circuit to adjust the output in order to vary the intensity of the LED light. When in full production the whole unit will be a lead-in, lead-out “lump in a cord” design with a remote control interface.

As of today, 2 March 2007, Dell has four power supplies listed on the 80PLUS.org website.

While the listing is several months after the competitor HP posted its high efficiency power supplies, the Dell units have significantly better efficiency and the potential of saving more energy and money.

This may be the first signal that Dell is taking the right steps to regain the crown as the leader in worldwide PC sales. It cannot regain the leadership just by squeezing the direct sales model. It has to do more, such as proving that it can be a technology leader.

Packing some of the most technologically advanced and energy efficient power supplies, to date, in their PCs, Dell proves that it can beat the competition on the technology field and is ready to start the uphill battle of regaining the leadership crown.
