B2405S-2WR2 降压型DC-DC电源模块产品概述

一、产品核心定位与基本属性

B2405S-2WR2是YLPTEC(易川) 推出的单通道降压型DC-DC电源模块,采用DIP通孔封装,专为24V直流供电系统设计,实现宽范围输入电压到稳定5V输出的转换,额定输出功率2W。该模块通过质量校验,具备短路保护功能,适配工业、通信等对可靠性有要求的中小功率场景,是简化系统电源设计的高性价比选择。

二、关键性能参数详解

1. 输入输出基础参数

  • 输入电压(Vin):支持21.6V~26.4V宽范围,覆盖24V系统±10%的电压波动(工业24V电源常见波动区间),无需额外稳压即可稳定工作;
  • 输出电压(Vout):精准5V直流输出,满足多数MCU、传感器等低压负载的供电需求;
  • 输出能力:最大输出电流400mA,额定功率2W(5V×400mA),可满足中小功率负载的持续供电(如小型数字电路、传感器模块)。

2. 效率与纹波控制

  • 转换效率:达80%,减少功率损耗,降低模块发热,提升系统能效(尤其适合对散热要求严格的紧凑设备);
  • 纹波噪声:≤100mVp-p,满足常规数字电路、传感器等对电源纹波要求不苛刻的负载的供电稳定性。

3. 隔离与负载适配

  • 隔离电压:1.5kVrms(交流有效值),符合工业场景电气隔离需求,避免高压侧与低压侧的干扰;
  • 容性负载能力:最大支持220uF,可兼容后端大电容滤波,进一步降低输出纹波。

4. 工作条件与物理尺寸

  • 工作温度:-40℃~+85℃,覆盖工业级宽温环境(如户外设备、高温车间);
  • 开关频率:100kHz,处于常规DC-DC开关频率区间,电磁干扰(EMI)相对可控;
  • 封装尺寸:19.5mm(长)×7mm(宽)×10mm(高),体积小巧,适配紧凑PCB布局。

三、核心技术特性与优势

1. 短路保护功能

内置过流/短路保护机制:当输出端出现短路或过流时自动切断输出,故障排除后可自动恢复,有效保护模块及负载设备,降低维护成本。

2. 宽输入电压适配

21.6V~26.4V的输入范围,兼容不同品牌24V电源的输出波动,无需额外添加稳压电路,简化系统设计流程。

3. 高隔离安全设计

1.5kVrms的隔离电压,满足IEC 60950等安全标准,避免不同电位模块之间的干扰,提升系统可靠性(尤其适合工业控制、通信设备等场景)。

4. 宽温工作能力

-40℃~+85℃的工作温度范围,适应工业环境的极端温度(如冬季户外低温、夏季车间高温),且2W功率发热低,无需额外散热设计。

5. 易安装DIP封装

采用通孔直插封装,焊接方便(支持手工焊接或批量波峰焊),封装牢固,抗振动能力优于贴片封装,适配工业设备的振动环境。

四、典型应用场景

  1. 工业控制设备:PLC(可编程逻辑控制器)辅助供电、温度/压力传感器模块的5V供电;
  2. 通信设备:24V供电的通信基站辅助模块、光纤收发器的5V电源转换;
  3. 安防监控系统:前端摄像头内部电路的5V供电(部分24V供电监控设备需转压);
  4. 车载电子(部分场景):12V/24V混合供电的车载显示屏、传感器的5V转换;
  5. 智能家居控制:24V供电的智能网关、环境传感器节点的5V供电。

五、可靠性与质量说明

该模块通过质量校验,符合工业级产品的可靠性要求;内置短路保护、宽温设计、高隔离等特性,可有效降低系统故障风险;DIP封装的机械强度高,适配振动环境,适合长期稳定工作。

综上,B2405S-2WR2是一款专为24V系统设计的高可靠性降压模块,平衡了性能、体积与成本,适配多场景中小功率供电需求。

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
