TDK-Lambda Americas Narrow-width DIN rail power supplies
These DRB series ac/dc DIN rail mount power supplies are rated to 120 and 240 W for continuous operation. Their narrow width allows additional devices to be installed on the rail, saving cabinet space. Their 93% efficiency produces less internal waste heat, enabling electrolytic capacitors to run cooler, extending field operating life to greater than seven years at 75% load, 230-Vac input. The power supplies can deliver a +20% peak load for up to 10 seconds. They are available with a 24-V output, adjustable from 24 to 28 V, and can accept an 85-to 264-Vac input withstanding surges of 300 Vac for 5 seconds.
