Power supplies lower off-load consumption


TDK-LAMBDA CSS65A series of ac-dc power supplies with an off-load power consumption of less than 75mW. Packaged in the industry standard 2” x 4” footprint with a low height of 1.08”, products accept a 90 to 264Vac input and is available with 5, 12, 15, 19, 24, 28, 48 and 54V outputs. The output power level is 40W for the 5V output and 65W for the 12 to 54V outputs. Remote sense is included, enabling the power supplies to compensate for load cable voltage drops. Average efficiency is 89% (86% for the 5V) and the units can operate at full load in ambient temperatures of up to 50C, and deliver up to 50% load at 70C without the need for external airflow. Leakage current is less than 100µA at 264Vac 63Hz.
