WRB1212S-3WR2 电源模块产品概述

WRB1212S-3WR2是YLPTEC(易川) 推出的一款小功率隔离式DC-DC电源模块,专为空间受限、宽温环境下的电子设备供电设计,具备高隔离安全、高效能转换、多重保护等核心特性,可广泛适配工业控制、通信、车载等多领域应用场景。

一、核心性能参数

模块性能参数围绕“宽适配、高可靠、小功率”核心设计,关键指标如下:

1. 输入输出规格

  • 输入电压:9V~18V宽范围直流输入,覆盖12V(常见车载/工业电源)、18V(部分通信设备电源)等主流供电系统,无需额外适配不同输入电压;
  • 输出性能:稳定输出12V直流电压,最大输出电流250mA,额定功率3W,满足单片机、传感器、小型通信模块等中小功率设备的供电需求;
  • 负载兼容性:最大可驱动680μF容性负载,适配后端电容滤波设计,输出纹波更平稳,保护敏感电路。

2. 效率与隔离

  • 转换效率:达80%,在额定功率下实现低功耗转换,减少模块自身发热,降低系统散热要求,延长设备寿命;
  • 电气隔离:1.5kVrms隔离电压,有效隔离输入输出端的电气干扰(如工业现场的高压串扰、通信系统的电磁噪声),提升系统安全性与抗干扰能力。

3. 开关与环境参数

  • 开关频率:300kHz,兼顾转换效率与EMI(电磁干扰)控制,降低对周边电路的干扰影响;
  • 工作温度:-40℃~+85℃宽温范围,满足低温车间、高温户外、车载等 harsh 工况,无需额外温控措施。

二、关键特性与优势

模块针对实际应用痛点设计,核心优势突出:

1. 宽温环境适应性

  • 覆盖工业级宽温区间,可在低温(如北方冬季户外)、高温(如车间烤箱旁、车载暴晒环境)下稳定工作,无需担心温度波动导致的性能下降。

2. 多重保护机制

  • 内置短路保护:输出端短路时自动切断输出,故障排除后自动恢复,避免模块损坏及负载二次故障,提升系统可靠性。

3. 紧凑封装设计

  • 采用SIP-7直插式封装,尺寸仅22mm(长)×9.5mm(宽)×12mm(高),体积小巧,适配嵌入式系统、小型仪器仪表等空间受限场景,焊接安装便捷。

4. 高可靠性设计

  • 宽输入电压范围降低电源波动影响,80%转换效率减少发热,结合宽温特性,模块长期工作故障率低,降低维护成本。

三、典型应用场景

WRB1212S-3WR2的特性使其可广泛覆盖以下领域:

1. 工业控制

  • PLC模块、传感器节点、小型执行器供电:适配工业现场的宽温、电磁干扰环境,保障设备稳定运行;

2. 通信设备

  • 小型基站、无线AP、通信模块辅助供电:满足低功耗、隔离安全需求,避免电源干扰影响信号传输;

3. 车载电子

  • 12V车载系统向敏感电路(如显示屏、胎压传感器)隔离供电:适应车载振动、宽温环境,提升电气安全;

4. 消费电子与智能家居

  • 智能门锁、小型充电设备、智能家居节点供电:体积小巧适配产品小型化趋势,稳定输出保障设备正常工作;

5. 低风险医疗设备

  • 体温监测仪、小型诊断设备供电:1.5kV隔离电压保障电气安全,避免医疗设备与人体接触时的潜在风险。

四、产品定位总结

WRB1212S-3WR2是YLPTEC针对中小功率隔离供电场景推出的高性价比解决方案,集“宽输入、高效能、宽温工作、短路保护、紧凑封装”于一体,解决了空间受限、环境严苛场景下的供电难题,为各类电子设备提供稳定可靠的电源支持,是工业、通信、车载等领域的理想电源选择。

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
