40-65W 2” x 4” AC-DCs with 75mW Off-load Consumption

June 28, 2017 by Paul Shepard

TDK Corporation announces the introduction of the 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", the series is suitable for many medical, clinical, test and measurement, process control, broadcast and communications applications.

The CSS65A accepts a 90- to 264-Vac input and is available with 5-, 12-, 15-, 19-, 24-, 28-, 48- and 54-V outputs. The output power level is 40W for the 5-V output and 65W for the 12- to 54-V outputs. Remote sense is included, enabling the power supplies to compensate for load cable voltage drops.

A choice of Molex or JST connectors is available for the input and output connectors. Average efficiency is 89% (86% for the 5V) and the units can operate at full load in ambient temperatures of up to 50 degrees C, and deliver up to 50% load at 70 degrees C without the need for external airflow. Leakage current is less than 100µA at 264Vac 63Hz.

The power supply has 4kVac input-to-output (2 x MoPPs), 1.5kVac (1 x MoPP) input-to-ground and 1.5kVac (1 x MoPP) output-to-ground isolation. All models are certified to ANSI / AAMI ES 60601-1, IEC / EN 60601-1, UL / CSA / IEC / EN 60950-1 and carry the CE mark for the Low Voltage and RoHS2 Directives. The CSS65A models comply with EN 55011-B and FCC-B conducted and radiated emissions, and meets the IEC 61000-3-2 harmonics, IEC 61000-4 and EN 60601-1-2 4th edition immunity standards.
