TDK Lambda's CSW65 series of AC-DC power supplies are rated at 40 W to 65 W output power. Accepting a very wide 90 V_AC to 305 V_AC input, the units can operate from 115 V, 230 V, and 277 V nominal inputs, are available in a U-channel construction, and have cover and/or DIN rail mounting clip options. Target applications include security, audio/video, and building automation systems.

Available output voltages include 5 V, 12 V, 15 V, 18 V, 24 V, 28 V, 48 V, and 54 V, have a no-load power consumption of less than 150 mW, and comply with DOE Efficiency Level VI requirements. Average efficiency levels are greater than 89% (87.2% for the 5 V model). The CSW65 measures 63.5 mm x 120.7 mm x 38.1 mm (W x L x H) and 63.5 mm x 120.7 mm x 47.2 mm with the DIN rail clip installed.

The series will operate convection cooled in ambient temperatures of -10°C to +70°C, derating linearly to 50% load from +50°C to +70°C. All the power supplies are certified to IEC/EN/UL/CSA 60950-1 with CE marking for the low voltage, EMC, and RoHS2 Directives. The CSW65 24 V output model has also been evaluated for NEC Class 2 limits in accordance with UL 1310. The series is compliant to EN 55032-B (radiated and conducted) and meets EN 55024 immunity standards.
