WRB4812S-3WR2 降压型DC-DC电源模块产品概述

一、产品定位与核心价值

WRB4812S-3WR2是YLPTEC(易川) 针对工业自动化、通信网络等场景开发的单通道降压型DC-DC电源模块,核心价值在于实现宽范围高压输入到稳定低压输出的高效转换,同时兼顾小体积、高可靠性与安全防护,为需要12V供电的小型设备提供可靠电源方案。

二、核心性能参数全面解读

该模块的关键参数覆盖电源设计的核心维度,具体如下:

  • 输入输出特性:输入电压范围36V~72V(兼容48V/60V等主流高压系统),输出电压稳定12V,最大输出电流250mA,额定输出功率3W(匹配250mA×12V的功率需求);
  • 效率与纹波:转换效率达80%(有效降低自身功耗,减少发热),输出纹波噪声≤100mVp-p(满足大部分常规电子设备的纹波要求);
  • 隔离与防护:电气隔离电压1.5kVrms(实现输入输出端安全隔离,避免高压串扰),内置短路保护功能(负载短路时自动切断输出,保护模块与负载);
  • 环境与尺寸:工作温度范围-40℃~+85℃(适应工业级宽温环境),SIP-7引脚封装,尺寸仅22mm×9.5mm×12mm(小体积便于嵌入紧凑设备);
  • 其他特性:开关频率300kHz(平衡效率与EMI性能),最大容性负载680uF(可直接驱动大电容负载,简化后端电路设计)。

三、典型应用场景

WRB4812S-3WR2的参数特性使其适配多种场景:

  1. 工业自动化:PLC模拟量模块、传感器节点、小型执行器的供电(宽温、隔离满足工业环境要求);
  2. 通信设备:基站辅助监控、OLT低压供电单元、通信电源二次降压(宽输入覆盖通信系统电压波动);
  3. 车载电子(部分场景):高压车载辅助控制模块的12V供电(需匹配输入电压范围);
  4. 小型嵌入式设备:物联网网关、智能仪表、小型医疗设备(小体积与高可靠性适配嵌入式需求)。

四、设计优势与差异化特点

相比同类模块,WRB4812S-3WR2具备以下优势:

  • 宽输入兼容性:36V72V覆盖48V系统(常见波动36V60V)与部分60V高压系统,无需额外电压适配;
  • 高可靠性防护:宽温工作、短路保护、1.5kV隔离三重防护,降低系统故障风险;
  • 小体积易集成:SIP-7封装仅22mm长,可直接通孔焊接,节省PCB空间;
  • 大容性负载能力:680uF负载无需并联限流电阻,简化后端电路;
  • 平衡效率与纹波:80%效率减少发热,100mVp-p纹波满足常规需求,无需额外滤波(特殊场景除外)。

五、应用注意事项

为确保稳定工作,需注意:

  1. 输入电压限制:严格控制在36V~72V,避免过压/欠压损坏;
  2. 负载电流控制:最大不超过250mA,可外接保险丝防护;
  3. 散热设计:自身功耗约0.6W,需PCB铜箔面积≥10cm²或预留散热空间;
  4. 安装方式:SIP-7封装适配通孔焊接,避免高温损坏模块;
  5. 隔离应用:1.5kV隔离适用于高压侧控制低压负载场景,无需隔离时不影响使用。

六、总结

WRB4812S-3WR2以宽输入范围、小体积、高可靠性为核心特点,覆盖工业、通信等多领域12V供电需求,是小型设备高压转低压供电的理想选择。

Sourcing availability signal

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
