## DESCRIPTION The RACM16E series features a compact 1”x2” standard footprint with corresponding pinning [P12] or with stranded wires. It operates with CV/CC constant current limited overcurrent protection, suitable for driving nonlinear loads. Designed for cost-effectiveness, these encapsulated modules deliver a full 16W output power at temperatures up to 65°C and accommodates extended nominal input voltage ratings from 100-277Vac with OVCIII conditions. With a safety agency-rated temperature range up to +85°C it ensures reliable performance. Certified with 2MOPP for altitudes up to 4000m, it also meets touch current limits for BF usage in medical health care applications. Optimized for standby power usage the no load power consumption is less than 100mW. The power supplies hold international safety certifications conforming to industrial IEC62368 and IEC61558 standards, medical UL/IEC/EN60601 standards, and household EN60335 standards. |SELECTION GUIDE|||||| |---|---|---|---|---|---| |Part|Input Voltage|Output Voltage|Output Current|Efficiency(1)|Output Power| |Number|Range|nom.|max.|typ.|max.| ||[VAC]|[VDC]|[mA]|[%]|[W]| |RACM16E-3.3SK/277|85-305|3.3|3640|78|12| |RACM16E-05SK/277(2)|85-305|5|3200|82|16| |RACM16E-12SK/277(2)|85-305|12|1330|84.5|16| |RACM16E-15SK/277|85-305|15|1066|85|16| |RACM16E-24SK/277(2)|85-305|24|667|86|16| |RACM16E-30SK/277|85-305|30|533|86|16| Note1: Efficiency is tested at 230VAC and full load at +25°C ambient copyright © RECOM Power GmbH, all rights reserved www.recom-power.com PRELIMINARY Page 1 Technical Data Sheet RACM16E-K/277 Series / AC/DC Power Supply 16W / Universal Input 100V-277VAC **AC/DC Converter** Model Numbering ## RACM16E- SK/277/ nom.
