RAC02-SE/277系列AC/DC转换器是RECOM公司设计的一款超紧凑型电源模块，专为高效节能应用而开发。该系列提供3.3V、5V、12V和24V多种输出电压选项，适用于 diverse 设备需求。产品享有3年保修期，确保长期可靠性和用户信心。关键特性包括最大无负载功耗仅为35mW，使其在睡眠模式和待机应用中表现出色；效率高达76%，有效减少能源损耗；输入与输出之间具有3kVAC/1分钟的电气隔离，提升安全性能。通用输入电压范围85-305VAC，兼容全球电网标准，适应各种环境。
在技术规格方面，模块尺寸为33.7mm x 22.2mm x 17.75mm，重量约24.5克，高度低于18mm，便于集成到空间受限的设计中。保护功能包括短路保护(SCP)和过压保护(OVP)，SCP支持连续自动恢复，OVP采用齐纳二极管钳位，范围110%-140%。工作温度范围-40°C至+85°C，热阻抗典型值8.5°C/W，确保在恶劣条件下稳定运行。输入频率范围47-440Hz，hold-up时间18ms（115VAC时），内部操作频率55kHz。输出纹波和噪声测量值，3.3V输出为300mVp-p，其他输出为250mVp-p，使用20MHz带宽和特定电容配置。
应用领域广泛，包括家庭自动化、工业控制、消费电子和嵌入式系统。产品通过多项认证，如EN/UL60950-1用于信息技术设备安全、EN60335-1用于家用电器、以及EN55022 Class B EMC标准。包装方式为管装，每管22个模块，存储温度-40°C to +85°C。MTBF数据基于MIL-HDBK-217F，在25°C时可达2238x10^3小时（115VAC）或1670x10^3小时（230VAC），突显高可靠性。
The ultra-compact RAC02-SE/277 modules are available with output voltages of 3.3, 5, 12 and
24V, and the input-to-output isolation is 3kVAC/1min. With a standby consumption of 35mW
maximum, the mini power supplies are particularly suitable for energy-saving sleep mode and
standby applications. Because of its compact design (height <18mm), it is a versatile solution for home
automation and other similar applications. Complete with an integrated input filter, the series has
enhanced EMI performance and complies with EN55022, class B. The mini power supplies are
also protected against short circuit with fully automatic restart after the error has been solved. The
converters are EN/UL60950-1 certified and come complete with a 3 year warranty.
