WRA2424S-3WR2 SIP隔离电源模块产品概述

YLPTEC(易川)推出的WRA2424S-3WR2是一款专为工业控制、通信设备及测试测量领域设计的2通道隔离电源模块,采用SIP封装,核心聚焦双路±24V输出需求,兼顾宽电压输入、高隔离防护与小尺寸集成,是替代传统分立电源方案的高效选择。

一、产品定位与核心优势

WRA2424S-3WR2针对需要正负隔离电源的中低功率场景,核心优势体现在以下三点:

  1. 宽适配性:输入电压覆盖18V~36V,兼容工业24V系统(含±25%波动)及部分24V/36V设备;双路±24V输出满足模拟电路(运放、ADC/DAC)的正负电源需求,无需额外设计多路电源;
  2. 高可靠性:内置短路保护,1.5kVrms隔离电压满足电气安全规范,-40℃~+85℃宽温范围适应恶劣环境;
  3. 小体积集成:SIP封装尺寸仅22mm×9.5mm×12mm,可直接插装PCB,节省空间,适合紧凑型设备设计。

二、关键性能参数详解

1. 输入输出特性

  • 输入范围:18V36V DC,覆盖工业常用24V电源(波动范围18V30V)及36V系统,无需额外降压/升压电路;
  • 输出规格:双路独立±24V输出,最大输出电流±63mA(单路),总功率3W,精准匹配中低功率模拟电路的供电需求(如16位ADC、精密运放的典型功耗);
  • 输出对称性:双路输出电压、电流参数一致,避免正负电源偏差对模拟电路精度的影响。

2. 能效与功耗

  • 转换效率:典型80%,相比传统线性电源(效率仅30%~50%)大幅提升,减少模块发热,降低散热成本;
  • 空载功耗:输入电流≤10mA(18V输入时),待机功耗低,适合长期运行的设备(如工业PLC的模拟量模块);
  • 开关频率:300kHz高频设计,缩小变压器体积,实现小尺寸封装,同时避免音频段噪声干扰。

3. 纹波与负载兼容性

  • 纹波噪声:≤100mVp-p(典型值),满足大多数模拟电路的噪声抑制要求(如传感器信号调理电路);
  • 容性负载:最大100uF,支持后端添加大容量滤波电容,进一步降低输出纹波,适配对噪声敏感的高精度电路。

4. 隔离与防护

  • 隔离电压:1.5kVrms(1分钟),有效隔离输入与输出端的电气干扰,保护后端敏感电路(如医疗设备、通信模块);
  • 短路保护:输出端短路时自动限流保护,故障排除后自动恢复,避免模块损坏,提高系统可靠性。

5. 环境适应性

  • 工作温度:-40℃~+85℃(工业级),可适应户外设备、车载电子及工业现场的极端温度环境;
  • 温度稳定性:宽温范围内输出电压波动控制在合理区间,不影响电路正常工作。

三、封装与安装设计

WRA2424S-3WR2采用SIP(单列直插式)封装,设计特点如下:

  • 尺寸参数:长度22mm×宽度9.5mm×高度12mm,体积紧凑,可嵌入小型设备内部;
  • 引脚设计:引脚间距符合标准PCB规范,可直接插装焊接,无需额外支架,安装简单;
  • 散热设计:模块自身通过引脚散热,无需额外散热片,简化系统布局。

四、典型应用场景

结合参数特性,WRA2424S-3WR2适用于以下场景:

  1. 工业自动化:PLC模拟量输入/输出模块、分布式IO模块的正负电源;
  2. 通信设备:光纤收发器、小型基站的辅助电源;
  3. 测试测量:示波器、信号发生器、数据采集卡的模拟电路供电;
  4. 医疗电子:低功率医疗仪器(如血压监测仪、心电图机)的隔离电源(需确认医疗认证);
  5. 车载电子:车载传感器模块、辅助控制系统的电源(宽温范围适配车载环境)。

五、可靠性与安全注意事项

  1. 防护建议:输出端可并联10uF~100uF电解电容+0.1uF陶瓷电容,进一步降低纹波;
  2. 安装注意:SIP封装引脚需焊接牢固,避免虚焊导致接触不良;
  3. 环境要求:避免在腐蚀性气体、高湿度环境中使用,如需则需额外防护;
  4. 认证确认:未明确标注是否通过CE、UL等认证,需根据应用场景确认是否满足合规要求。

总结

WRA2424S-3WR2是一款高性价比的双路隔离电源模块,以宽输入范围、小尺寸、高可靠性为核心,完美适配工业控制、通信、测试测量等领域的正负电源需求,是简化电路设计、降低成本的理想选择。

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
