The power supplies can operate from an 85 to 264VAC input, and are initially available with 12, 18, 24 or 48V nominal outputs. With efficiencies of up to 94%, the CUS350M meets the ErP Directive with an average efficiency rating of greater than 87% and a stand-by power consumption of less than 0.5W. Less internal waste heat allows the product to conservatively operate at full power in -20 to +40ºC ambient temperatures, and up to +70ºC with derating.
The compact CUS350M measures 190x87mm, with a height of 40mm for 1U rack mounting. The preferred “/F” suffix models have a 5V 0.5A standby output, an auxiliary 12V 0.3A output, remote sense, remote on/off and an isolated DC good signal.
The CUS350M series has an input to output isolation of 4,000VAC (2 x MOPPs), 2,000Vac from input to ground (1 x MOPP) and 1,500VAC (1 x MOPP) from output to ground. Safety certifications include IEC/EN 60601-1, ANSI/AAMI ES 60601-1 and IEC/EN/US 60950-1 with CE marking for the Low Voltage and RoHS2 Directives. The units also comply with EN 55011-B, EN 55022-B and FCC Class B for conducted emissions (Class A radiated) and meet the IEC 61000-4 immunity standards.
