40-65W Industrial Power Supplies Accept 90- to 305-Vac Inputs

TDK Corporation announces the introduction of the CSW65 series of ac-dc power supplies, rated at 40- to 65-W output power. Accepting a very wide 90- to 305-Vac input, the units can operate from 115V, 230V and 277V 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, 12, 15, 18, 24, 28, 48 and 54V, have a no-load power consumption of less than 150mW and comply with DOE Efficiency Level VI requirements. Average efficiency levels are greater than 89% (87.2% for the 5V model). The CSW65 measures 63.5 x 120.7 x 38.1 mm (W x L x H) and 63.5 x 120.7 x 47.2 mm with the DIN rail clip installed.

The series will operate convection cooled in ambient temperatures of -10 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 24V 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.
