YLPTEC WRA2412S-3WR2 降压型DC-DC电源模块产品概述

一、核心功能与应用定位

YLPTEC WRA2412S-3WR2是一款双路降压型DC-DC电源模块,专为需要正负对称输出的工业/仪表场景设计,可直接将18V~36V宽范围输入电压转换为±12V稳定输出,解决单电源系统转双电源的设计痛点,无需额外配置电压反转电路,简化系统架构。

二、关键性能参数详解

该模块的核心参数覆盖输入输出、效率、隔离、可靠性等关键维度,具体如下:

1. 输入输出特性

  • 输入电压范围:18V~36V DC,兼容工业常用24V电源(±20%波动仍稳定),也可适配36V高压场景,适应电源波动能力强;
  • 输出电压:双路同步输出±12V DC,两路电压精度一致,满足对称负载需求;
  • 输出电流/功率:每路最大±125mA,总输出功率3W,可驱动中等负载(如运放、传感器调理电路等);
  • 纹波噪声:50mVp-p(典型值),低噪声特性适合对电源敏感的模拟信号处理电路(如医疗仪器、测试仪表)。

2. 效率与可靠性

  • 转换效率:78%(典型值),在降压模块中处于实用水平,发热可控,无需额外散热片即可稳定工作;
  • 隔离电压:1.5kVrms(交流有效值),满足电气安全隔离要求,防止前端高压故障干扰后端敏感电路;
  • 保护功能:内置短路保护,输出端短路时自动限流/切断,故障排除后自动恢复,无需手动重置;
  • 工作温度:-40℃~+85℃(工业级宽温范围),可适应户外低温、控制柜内高温等恶劣环境。

3. 其他特性

  • 开关频率:300kHz,属于中等频率,既避免高频EMI干扰,又无需过大滤波电容即可实现低纹波;
  • 容性负载兼容性:最大支持470uF外接电容,方便用户根据需求进一步降低纹波或稳定负载。

三、封装与物理尺寸

采用SIP(单列直插)封装,体积紧凑:

  • 长度:22mm,宽度:9.5mm,高度:12mm;
  • 引脚间距合理,便于PCB焊接或直接插装,适合空间受限的小型化设备(如手持测试仪器、小型PLC模块)。

四、典型应用领域

该模块因双路正负输出、宽温范围、低纹波等特性,广泛应用于以下场景:

  1. 工业自动化:PLC模拟量输入输出模块、传感器信号调理电路(如压力/温度传感器的运放供电);
  2. 测试测量:示波器、信号发生器等仪器的信号处理单元(需要正负电源驱动运放);
  3. 医疗仪器:监护仪、心电图机等设备的传感器供电(低纹波保障信号精度);
  4. 通信设备:小型基站的辅助电源模块(宽输入适配不同供电);
  5. 车载电子:部分12V/24V车载系统的辅助电源(宽温适应车内温度变化)。

五、产品优势总结

  • 简化设计:双路±12V直接输出,无需额外电压反转电路;
  • 稳定可靠:宽温范围、短路保护、1.5kV隔离,满足工业级可靠性要求;
  • 紧凑适配:SIP封装体积小,适合小型化设备;
  • 低噪声:50mVp-p纹波,适配敏感模拟电路。

该模块通过校验认证,是工业、仪表等领域需要双路正负电源场景的高性价比选择。

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
