B2405S-1WR3 隔离型降压电源模块(插件)产品概述

B2405S-1WR3 是 YLPTEC(易川)推出的一款高密度、单路隔离降压型直流-直流电源模块,专为24V类母线系统向低压逻辑或模拟电路提供稳定隔离电源而设计。模块采用 SIP 插件封装(尺寸 11.6 × 6 × 10.16 mm),功率 1W,输出 5V/200mA,兼顾体积、效率与可靠性,适用于工业控制、仪表、通信设备等对隔离和低噪声有要求的场合。

一、主要规格要点

  • 功能类型:降压型(隔离型 DC-DC)
  • 通道数:1 路
  • 输入电压范围:21.6V ~ 26.4V(典型用于 24V 系统)
  • 输出电压/电流:5V / 最大 200mA(1W)
  • 转换效率:典型 88%
  • 隔离耐压:1.5 kV RMS
  • 开关频率:260 kHz
  • 空载输入电流:8 mA
  • 纹波噪声:典型 30 mV p-p
  • 最大容性负载:2400 μF
  • 特性:短路保护
  • 工作温度范围:-40 ℃ ~ +105 ℃
  • 封装:SIP 插件,尺寸 11.6 × 6 × 10.16 mm

二、电气性能与能耗估算

在满载(1W 输出)且效率 88% 时,输入功率约为 1W / 0.88 ≈ 1.136W;以典型 24V 输入计算,输入电流约为 1.136W / 24V ≈ 47 mA。模块自身空载输入电流为 8 mA,在待机或低负载工况下整体系统功耗较低。输出纹波典型 30 mV p-p,满足大多数数字电路和模拟前端对低噪声电源的需求。

三、保护与可靠性

模块内置短路保护,有助于在输出短路或过载时保护模块本体和下游电路。额定隔离电压 1.5 kV RMS 可提供合理的安全隔离,适用于信号隔离、地环路消除及安全隔离场景。长期工作温度范围宽(-40~+105 ℃),适合工业级应用环境。

四、机械与封装

SIP 插件式封装便于直接插入 PCB 并进行波峰或手工焊接,占板面积小、垂直高度约 10.16 mm,适合空间受限的控制板或信号隔离模块。最大可驱动 2400 μF 的容性负载,便于在输出端并联较大容量滤波电容以降低低频纹波与瞬态响应。

五、应用建议与选型要点

  • 应用场景:工业控制与传感、隔离型信号采集、通信设备供电、分布式传感节点、继电器/驱动器辅助电源等。
  • 输入侧建议:在电源输入端并联适当的滤波电容(低 ESR 电解或陶瓷)与熔断/浪涌抑制件,保证模块在有干扰或启动浪涌时稳定工作。
  • 输出侧建议:为保证瞬态响应与降低纹波,可并联低 ESR 电容(推荐组合陶瓷+电解),但总容性负载不要超过 2400 μF。
  • 布局注意:尽量缩短输入与输出回路的连接距离,保持接地良好;模块周边避免高温器件密集布局,以利散热。
  • 热设计:模块效率高但仍有小量损耗,保证周围空气流通;在高环境温度或密闭空间应适当降载或增加散热条件。

六、使用注意事项

  • 请在额定输入范围内使用,避免长期在超出范围的电压上工作。
  • 初次调试与批量使用前建议进行绝缘耐压与功能测试,验证短路保护与热稳定性。
  • 如需并联多个模块或与其他电源共享负载时,注意地隔离关系与输出非并联设计限制(多数隔离模块不建议直接并联)。
  • 对于安全关键或需认证的场合,请在采购前确认认证状态与厂商技术支持。

七、总结

B2405S-1WR3 以紧凑的 SIP 插件封装、高达 1.5 kV 的隔离能力、较高的转换效率(约 88%)和工业级工作温度覆盖,为 24V 母线向 5V 隔离供电提供了一种体积小、性能稳定的解决方案。其短路保护、较低的空载电流和对容性负载的良好支持,使其在工业控制、仪表与通信等需要隔离与低噪声电源的场合具有较高的适用性。若需进一步的引脚信息、典型接线或样品测试数据,可联系供应商或查阅完整规格书。

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.
