The CUS1500M series extends TDK-Lambda’s 30 to 350W CUS-M range with seven year warranties.
The supplies operate from a wide-range input of 85 to 265Vac with an earth leakage current of <300µA, and can be used in ambient temperatures of -20 to +60°C, derating linearly above 50°C to 60 percent load at 60°C. A variable speed fan ensures low acoustic noise. The units are available with 12V, 15V, 24V, 36V and 48V outputs, adjustable by -15/+20% (48V:-15/+10%) to accommodate non-standard voltages.
The fully featured series has an isolated 5V 1A standby voltage, remote on/off, an output-low/fan-fail isolated signal and parallel capability for up to five units. Screw terminal blocks with covers, rather than busbars, simplify the connection of multiple cables. The output terminal blocks can be user configured for vertical or horizontal orientation for easy cable routing. The case dimensions are a compact 127 x 63 x 261mm.
The units are safety certified to IEC/EN/ES/CSA 60601-1, IEC/EN/US/CSA 60950-1 (IEC 62368-1 pending), EN 62477-1 (OVC III), with CE marking for the Low Voltage, EMC and RoHS2 Directives. Input to output isolation is 4,000Vac (2 x MoPP), input to ground 2,000Vac (1 x MoPP) and 1,500Vac output to ground (1 x MoPP) for suitability with B and BF rated equipment. The units also comply with EN 55011-B and EN 55032-B conducted and radiated emissions, meet the EN 61000-3-2 harmonics and EN 60601-1-2 (Edition 4) immunity standards.
