Low-Profile DIN Rail-Mount Power Supplies

TDK-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.
