Single-output unit delivers concentrated power
Lambda has introduced a new single-output version of its 1000W Alpha, making it the most versatile configurable power supply available with a full range of power levels from 400W to 1000W
250W power supply gives users greater flexibility
Flexi Sirius from Lambda, the world's number one power supply manufacturer, is the latest addition to the company's range of advanced configurable power supplies.
Martin Southam Lambda's UK sales director comments: "Since the introduction of the first 400W and 600W Alpha units customer power demands have steadily risen.
Customer demand saw the introduction of a 1000W unit last year and now these same customers want 1500W in a case size matching our competitors' 1000W products.
The advantage of configurable power supplies is that our design team can quickly upgrade product platforms to satisfy our customers' needs." Careful redesign has allowed Lambda designers to increase the output of Alpha's forward converters to 500W.
With 8 configurable module slots instead of the 7 to be found on the 1000W unit, the new 1500W Alpha has a slightly larger footprint.
Height and length remain the same at 63 x 279mm, while width has been increased to 200mm.
With an input voltage range of between 207 and 264V AC and an input frequency of 47 to 63Hz, the CE-marked Alpha 1500 has a start-up time of less than 0.5s.
Output adjustment is via a multi-turn potentiometer with an accuracy to within 1%.
Load regulation (0 to 100% loading) is <0.5% with remote sensing and <2% without remote sensing.
Overcurrent and overvoltage are fitted as standard as is thermal protection.
Input protection is in accordance with EN61000-4-2/4/5 level 3.
Cooling is provided by two 60mm fans.
The new power supply has built-in power factor correction and harmonic correction in accordance with EN61000-3-2.
The latest addition means that Lambda now offers its leading power supply across the full range of power levels from 400W to 1500W with up to 14 outputs.
Alpha's inherently flexible modular design means that for those customers whose voltage requirements lie beyond that of standard units, Lambda is able to provide a carefully matched solution that is easy to specify, easy to fit, easy to buy. Request a free brochure from Lambda ...
