WRA2409S-3WR2 降压型双路输出电源模块概述

WRA2409S-3WR2是YLPTEC(易川)推出的工业级降压型双路隔离电源模块,专为需要正负对称输出、宽电压适配及高可靠性的场景设计,集成短路保护、宽温工作等特性,可满足嵌入式系统、工业自动化等领域的供电需求。

一、产品定位与核心功能

该模块聚焦双路±9V对称输出的供电痛点,替代传统“单路电源+分压电路”的复杂设计,同时通过1.5kVrms隔离解决高压/低压端的电气干扰问题。核心功能包括:

  1. 宽范围降压转换:将18V~36V直流输入转换为双路稳定±9V输出;
  2. 电气隔离防护:输入输出端完全隔离,避免共地干扰与安全隐患;
  3. 异常保护:内置短路保护机制,防止负载短路损坏模块或系统。

二、关键电气参数详解

1. 输入输出特性

  • 输入电压(Vin):18V~36V宽覆盖,适配24V工业母线、车载24V系统等多种电源场景;
  • 输出电压(Vout):双路对称±9V,输出精度满足模拟电路(如运放)、数字逻辑电路的供电要求;
  • 输出电流(Imax):单路最大±167mA,总功率3W(9V×0.167A×2≈3W),可驱动中等功率负载(如传感器、小功率执行器);
  • 空载电流:仅10mA,低功耗特性适合待机或低负载场景,减少系统能耗。

2. 转换与纹波表现

  • 转换效率:81%,在3W功率等级下实现较高能效,降低模块自身发热;
  • 开关频率:300kHz,中高频设计缩小磁性元件体积,是模块小尺寸的核心支撑;
  • 纹波噪声:100mVp-p,满足大多数模拟电路对电源纹波的要求,无需额外滤波即可稳定工作;
  • 容性负载能力:最大680uF,兼容大容性负载场景,避免负载突变导致的电压波动。

3. 隔离与防护参数

  • 隔离电压(Vrms):1.5kV,符合工业级隔离标准,可有效隔离高压端与低压控制端的干扰;
  • 短路保护:输出短路时自动限流/切断,提升系统安全性,降低维护成本。

三、物理特性与封装

  • 封装形式:SIP-7(单列直插式),引脚布局简洁,便于PCB焊接与系统集成;
  • 尺寸规格:22mm(长)×9.5mm(宽)×12mm(高),小体积适配空间紧凑的嵌入式设备(如小型工业仪表、车载控制器);
  • 工作温度:-40℃~+85℃,宽温特性可适应工业现场极端环境(如低温户外、高温车间)。

四、典型应用场景

WRA2409S-3WR2的参数特性使其适用于以下场景:

  1. 工业自动化:PLC模拟量模块、传感器节点的正负电源供电(隔离避免现场电磁干扰);
  2. 通信设备:基站辅助电源、光纤收发器的电源转换(宽输入适配通信母线电压);
  3. 车载电子:24V卡车/工程车的车载终端、监控设备供电(宽温+宽输入适配车载环境);
  4. 医疗设备:小型监护仪、输液泵的隔离电源(1.5kV隔离满足医疗安全标准);
  5. 嵌入式系统:需要正负电源的单片机、DSP开发板供电(小体积适配开发板空间)。

五、产品优势总结

  1. 集成化简化设计:双路正负输出+隔离功能一体化,无需额外搭建分压电路,缩短系统开发周期;
  2. 工业级可靠性:宽温工作、短路保护、高隔离电压,满足严苛工业环境要求;
  3. 小体积低功耗:SIP-7封装与300kHz开关频率,实现小尺寸与低空载电流,适配紧凑场景;
  4. 宽适配性:18V~36V输入覆盖多种电源系统,±9V输出满足模拟/数字电路供电需求。

该模块凭借以上特性,成为工业控制、通信、车载等领域实现隔离双路供电的优选方案。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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.

Replenishment inquiry Typical RFQ workflow
