These external power supplies are packaged in compact, insulated, and lightweight enclosures that measure 2.71 in. wide by 5.2 in. long by only 1.57 in. high and are convection cooled (no fans needed). The operating temperature range is 0 to 40°C at full load (derate linearly to 50% load at 60°C). All models are fully isolated (3 kVAC, input to output) and units from 12 through 24 V are California Energy Commission (CEC) and Energy Independence Act of 2007 (EISA) Level IV compliant. Plus, some models with output voltages of 15, 18, and 24 V are EISA and CEC Level V compliant.
These energy-saving supplies include overvoltage and short-circuit protections and the Off/No-Load standby-power-consumption is less than 0.50 watt, as required by the green energy initiatives. In addition, these supplies include UL/EN/IEC60950-1 international safety agency certifications and meet EN55022-B and FCC Class B conducted and radiated EMI standards.
