Lambda Introduces Industry's Highest Density 450W/650W Modular Power Supply
SAN DIEGO, CA (MAY 17, 2002) - Leading power supply manufacturer, Lambda, introduces its latest innovation, the Vega Series AC-DC modular power supply. Designed as a standard configurable product, the Vega utilizes off-the-shelf modules and converters that can be quickly assembled to meet custom output specifications. This eliminates the need for high cost, long lead-time, custom power supplies.
These configurable switch mode power supplies offer designers a higher level of reliability and flexibility than previously available for demanding power requirements. Featuring lower overall component counts and a single PCB design in both the front-end converter and output module stages, the Vega Series provides superior reliability. Assembly time of the modules and converters is thereby reduced by up to 70% over conventional modular products. Initially offered in two packages of 450W and 650W, Lambda can meet turnaround times of two weeks for evaluation units and six weeks for production volumes.
The modular design enables configurations to support typical applications from computer peripherals, to automated test systems and industrial equipment. This is where low voltage/high current outputs up to 114A, as well as high voltage outputs including 36V, 48V, and 62V multiple output combinations are typically used.
"Developed by a combined team of engineers from the UK, the US and Japan, the Vega Series is an example of Lambda's global design capability," said Dorrel Vernon, Lambda Product Manager. "Using a global team of engineers enabled Lambda to quickly address new trends in the market such as high current, low-voltage system architectures in just 12 months from conception to production. The goal was to produce a compact power supply that resulted in Vega's superior density of 5.8W/in3 for the system air package. With the Vega Series' versatility, we can address thousands of multiple output configurations without the incurred NRE cost and long development time typically encountered with custom designs."
The Vega Series provides a seamless output voltage range from 1.8V to 62V, with higher voltages possible by series operation (the input ranges are 85 - 264 VAC). "This makes the Vega the most configurable power supply available," added Vernon. The 450W and 650 packages provide a maximum of 10 outputs with no minimum load requirements and offer overvoltage and over current protection as standard features.
Ensuring worldwide compatibility, Vega is compliant to EN61000-3-2 power factor correction standards, IEC 1000-4 input transient immunity standards and meets EMI level B conducted, and level A radiated standards. The series also has CE Marking, UL 1950, CSA22.2 No.950, UL3101-1, UL2601-1 (models with < 300uA leakage), and EN60950 worldwide safety agency approvals.
Options of the 450W and 650W Vega Series units include fast on-tab/screw input or output connection, IEC input connection, and multiple cooling options including system air, end fan, end fan with reverse airflow, quiet fan. Standard signal options include mains fail, global inhibit, output good and output inhibit Low leakage versions are also available with input filter ratings as low as 42uA, which when combined with the Vega's standard input-output isolation rating of 4,000 VAC is compliant with UL2601 medical standards.
Several auxiliary output options are available for stand-by power once AC input is maintained to the power supply. These include 5V@100mA, 5V@300mA, or an adjustable 5-15V auxiliary output at 1A.
The Vega Series is positioned competitively with pricing averaging $0.80/W when purchased in OEM quantities.
