YLPTEC WRA2405S-3WR2 3W双路隔离降压电源模块概述

YLPTEC(易川)推出的WRA2405S-3WR2是一款3W小功率双路隔离降压电源模块,针对工业控制、车载电子、通信设备等场景的隔离供电需求设计,具备宽输入电压范围、对称±5V输出、1.5kVrms隔离电压及短路保护等核心特性,体积紧凑(22×9.5×12mm),适配多种紧凑型电路设计。

一、产品定位与核心特性

该模块定位于中低端压隔离供电场景,解决电路间电气隔离、正负电源同时供电的需求,核心特性可总结为:

  1. 双路对称输出:同时提供±5V稳定电压,最大输出电流各300mA,满足运放、ADC/DAC、传感器信号调理等需要正负电源的电路;
  2. 宽输入电压覆盖:18V~36V输入范围,精准匹配工业24V系统(典型24V,波动±12V),无需额外降压适配;
  3. 安全隔离设计:1.5kVrms隔离电压,有效隔离输入输出端的电气干扰,保护敏感电路(如模拟信号链);
  4. 可靠保护机制:内置短路保护功能,输出短路时自动关断,故障排除后可自恢复(需结合实际应用验证);
  5. 工业级宽温工作:-40℃~+85℃工作温度范围,适应户外、车载等恶劣环境;
  6. 紧凑封装:SIP-7插针封装,体积仅22×9.5×12mm,便于PCB插装/焊接,节省空间。

二、关键参数解析

模块参数围绕“小功率隔离降压”核心设计,各关键参数的实际意义如下:

  • 输出功率3W:双路总功率2×5V×0.3A≈3W,属于轻载模块,适合传感器节点、小型控制单元等场景;
  • 转换效率78%:同功率段隔离DC-DC的中等水平,发热可控(3W×22%≈0.66W,需注意散热);
  • 纹波噪声50mVp-p:峰峰值50mV的纹波,满足12位ADC、MCU等数字/中精度模拟电路的供电需求;
  • 最大容性负载1000uF:带载容性负载能力较强,可直接驱动大容量滤波电容,无需额外限流;
  • 开关频率300kHz:高频设计减少电感/电容体积,EMI相对低频模块更易控制,符合EMC标准。

三、典型适用场景

WRA2405S-3WR2的参数特性决定了其在以下场景的实用性:

  1. 工业控制:PLC模拟量I/O模块、远程IO单元的隔离供电,为运放、ADC提供±5V电源;
  2. 车载电子:24V卡车、工程机械的传感器信号调理电路,满足宽温(-40~85℃)及抗干扰需求;
  3. 通信设备:小型基站、路由器的辅助控制电路,隔离电磁干扰提升稳定性;
  4. 基础医疗电子:小型监护设备、血糖检测仪的低功耗电路供电(1.5kVrms满足基础隔离);
  5. 智能家居:智能门锁传感器模块的隔离供电,避免市电干扰。

四、封装与可靠性设计

  • SIP-7封装:标准插针式,引脚布局合理,无需贴片工艺,适合小批量原型开发;
  • 宽温可靠性:-40~85℃覆盖工业级环境,通过短路保护测试,可承受短期过载;
  • 散热优化:无额外散热片,但需预留PCB散热铜箔或涂抹导热硅脂,满载时环境温度建议不超70℃。

五、应用注意事项

  1. 滤波提升:输入/输出端并联10~100uF电解电容+0.1uF陶瓷电容,可进一步降低纹波;
  2. 隔离端处理:输入输出严格电气隔离,避免共地破坏隔离特性;
  3. 负载限制:单路电流≤300mA,总功率≤3W,避免过载;
  4. 散热强化:焊接时模块底部涂导热硅脂,PCB预留散热铜箔。

总结:WRA2405S-3WR2是一款性价比高的小功率隔离模块,适合对功率、隔离、宽温有基本需求的工业/车载场景,紧凑封装与可靠保护使其成为原型开发及批量生产的实用选择。

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.
