SAN DIEGO – TDK-Lambda Americas Inc. in San Diego is introducing the CUS500M1 AC-DC power supplies for test and measurement, industrial, broadcast, and medical equipment.
The TDK-Lambda brand CUS500M1 AC-DC power supply series is rated at 500 Watts and comes in a 3-by-5-inch package. It provides an alternative for the 600-Watt CUS600M models and is an alternative for low-power cost-sensitive applications.
The CUS500M1 AC-DC power supply series accepts an 85 to 264 volts AC input and has a choice of seven output voltages: 12, 19, 24, 28, 32, 36 and 48 volts. A fan option with cover also is available.
The open-frame models measure 76.2 by 127 by 37 millimeters, or 85 by 157 by 42.5 millimeters with the fan cover fitted. The convection-cooled CUS500M1 can deliver 300 Watts (500 Watts peak) in -20 to 40-degree Celsius ambient temperatures, derating linearly to 150 Watts load at 70 C.
With forced-air cooling or the integral fan fitted, the power supply series provides as much as 500 Watts in a 60 C ambient, derating to 400 Watts at 70 C. The efficiency of the series is as much as 96 percent.
The CUS500M1 has an input-to-output isolation of 4,000 volts AC, an input-to-ground isolation of 2,000 volts AC, and an output-to-ground isolation of 1,500 volts AC for suitability in B- and BF-rated medical equipment. The leakage current is less than 200 microamps and the touch current is less than 100 microamps. The maximum operating, transportation and storage altitude is 16,404 feet.
Safety certifications include IEC/EN/ES 60601-1 and IEC/EN/UL 62368-1 with CE and UKCA markings for the low-voltage, EMC, and RoHS directives. The units also comply with EN 55011-B and EN 55032-B conducted and radiated emissions, and meets the EN 61000-3-2 harmonics, IEC60601-1-2 Edition 4 and IEC 61000-4 immunity standards.
