Lambda Launches New Series of Low-Profile DIN Rail-Mount Power Supplies for Installation in Shallow Enclosures

SAN DIEGO, CA (April 11, 2007) - Lambda has introduced a series of low-profile DIN rail-mount power supplies only 2.2 inches deep, making them ideal for installation in shallow enclosures commonly used in building automation and security applications.

The new DSP series supplies are available with nominal outputs from 5 to 24 volts and power levels from 10 to 100 watts in four packages sizes. Load regulation is less than 1% from no load to full load, with ripple and noise below 50 millivolts. To compensate for cable voltage drops, the output voltage can be adjusted from the front panel, and colored LED indicators give an immediate visual confirmation of output status.

The power supplies feature universal input, allowing them to operate from any AC input voltage between 90 to 264VAC, 47 to 63Hz, without the need to reposition input voltage selector switches. Because the units are Class II (double insulated), no earth ground wire is required.

Models are approved to UL60950-1, EN60950-1 and UL1310 specifications (less than 4- amp units) and are listed to UL508. The supplies are convection cooled and can operate at full power over a wide temperature range of -25°C to +61°C, derating linearly at 2.5% of a degree above 61°C to 71°C.

The units are enclosed in a plastic case measuring just 0.71 x 3.58 x 2.2 inches (10W models) to 3.54 x 3.58 x 2.2 inches (100W models) and will mount on either a TS35/7.5 or TS35/15 DIN rail.

DSP series power supplies are available now, with prices starting at $20.50 each in 10- quantities. More information can be found at Lambda's Web site,
