B1515S-3WR2 隔离式DC-DC电源模块产品概述

B1515S-3WR2是YLPTEC(易川)推出的一款1通道隔离式DC-DC电源模块,针对中小功率隔离供电场景设计,兼具高转换效率、宽电压兼容、小体积等特点,可满足工业控制、通信设备、医疗电子等领域的供电需求。

一、核心定位与品牌背景

YLPTEC(易川)作为专注电源模块研发的品牌,产品以可靠性高、性价比优著称。B1515S-3WR2定位于低功率隔离供电解决方案,解决了普通非隔离电源的串扰问题,同时兼顾效率与体积,适合对空间和隔离安全有要求的设备设计。

二、关键性能参数亮点

该模块核心性能围绕“隔离安全、高效稳定、小体积兼容”展开,关键参数及优势如下:

2.1 功率与效率

  • 额定输出功率3W,匹配中小功率设备需求;
  • 转换效率达88%,相比同类3W模块发热更低,长期工作可靠性更强;
  • 空载输入电流仅4mA,待机功耗极低,适合长时间待机的设备(如工业传感器、手持仪器)。

2.2 电压与电流特性

  • 输入电压范围:13.5V~16.5V,兼容常见15V直流电源波动(如适配器输出波动、电池放电后期电压);
  • 输出电压稳定15V,最大输出电流200mA(3W/15V=200mA),电流余量充足;
  • 输出纹波噪声80mVp-p,属于低噪声级别,满足模拟电路(如传感器信号放大)或敏感数字电路的供电要求。

2.3 隔离与安全

  • 隔离电压1.5kVrms,符合工业级隔离安全标准,有效隔离输入输出端电气干扰,避免设备串扰;
  • 内置短路保护功能,输出短路时自动切断电路,故障排除后需断电重启恢复,防止模块损坏。

2.4 负载与电磁兼容性

  • 最大容性负载560uF,无需额外限制负载电容,简化电路设计;
  • 开关频率250kHz,处于高效区间且避开音频频段,减少电磁干扰(EMI),多数场景无需额外EMI滤波。

三、封装与物理特性

B1515S-3WR2采用SIP-4插针式封装,尺寸仅19.65mm×10.16mm×7mm,体积小巧,可轻松集成到空间紧凑的设备内部(如手持仪器、小型通信模块)。插针式设计便于焊接安装,适合批量生产。

四、典型应用场景

结合模块隔离、低功耗、小体积等特性,典型应用包括:

  1. 工业自动化:PLC模块传感器供电、现场总线接口隔离(1.5kV隔离避免现场电磁干扰);
  2. 通信设备:小型基站射频模块供电、路由器LAN/WAN接口隔离(小体积适配设备紧凑设计);
  3. 医疗电子:监护仪生理传感器供电(低噪声保障信号精度,隔离提升安全);
  4. 仪器仪表:手持万用表、示波器内部隔离供电(宽输入兼容电池/适配器,低空载延长待机);
  5. 消费电子:智能家居设备模块供电(短路保护提升可靠性)。

五、使用注意事项

为保障模块稳定工作,需注意:

  1. 输入电压严格控制在13.5V~16.5V范围内,超出可能导致过热或损坏;
  2. 输出端容性负载不得超过560uF,避免启动冲击电流过大;
  3. 焊接温度≤260℃,每个引脚焊接时间≤5秒,防止封装变形;
  4. 短路保护触发后,断电1~2秒再重启可恢复正常;
  5. 工作环境避免高温潮湿,建议通风良好位置安装。

综上,B1515S-3WR2以高性价比、可靠隔离、小体积等优势,成为中小功率隔离供电场景的实用选择,可满足多领域设备的供电需求。

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
