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。
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。
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。
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)。
-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。
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。
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。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
