WRA1215S-3WR2 工业级DC-DC电源模块产品概述

YLPTEC(易川)针对工业场景电源需求推出的WRA1215S-3WR2,是一款双路隔离式DC-DC电源模块,核心定位为“小体积、宽适配、高可靠”,集成短路保护、宽温工作等实用特性,可满足工业控制、通信设备等领域对正负电源的精准供电需求。

一、核心参数与性能亮点

WRA1215S-3WR2的参数覆盖电源转换全链路,关键指标精准适配工业级应用:

  • 输入输出特性:输入电压兼容9V~18V宽范围(直接匹配12V、15V主流工业电源,无需额外调压),输出为**±15V对称双路**,每路最大输出电流±100mA,额定功率3W,可同时满足两路独立负载的供电需求;
  • 转换效率:典型效率达80%,在3W额定功率下能量损耗低,无需附加散热片即可稳定工作,降低系统功耗;
  • 隔离与负载:1.5kVrms隔离电压符合工业级安全标准,可有效隔离输入输出端的共地干扰;最大容性负载220uF,支持后端滤波电容扩容,进一步抑制纹波;
  • 纹波与噪声:输出纹波噪声控制在100mVp-p以内,适合对电源纯净度敏感的模拟电路(如运放、高精度ADC/DAC);
  • 工作特性:开关频率300kHz(频率稳定,减少电磁干扰EMI),工作温度范围-40℃~+85℃(覆盖工业现场极端环境,如户外设备、低温车间),集成短路保护功能(输出短路时自动限流,故障排除后自动恢复,避免模块及负载损坏)。

二、设计优势与技术特性

WRA1215S-3WR2的设计聚焦工业场景痛点,具备以下实用优势:

  1. 宽电压输入适配:兼容9V~18V输入,可直接对接12V(汽车/工业电源)、15V等多种输入源,简化系统设计流程,无需额外设计调压电路;
  2. 双路对称输出:±15V双路输出电流完全一致(±100mA),避免两路电源功率失衡,尤其适合需要正负电源的模拟电路(如PLC模拟量模块、伺服驱动器控制端);
  3. 高隔离安全可靠:1.5kVrms隔离电压满足工业电气安全标准,可有效隔离前端输入与后端负载,防止高压串扰、共地干扰,提升系统抗干扰能力;
  4. 宽温与保护特性:-40℃~+85℃工作温度覆盖工业现场90%以上极端场景,短路保护功能可在输出短路时快速响应,避免模块烧毁;
  5. 紧凑封装布局:采用SIP(单列直插式)封装,尺寸仅22mm×9.5mm×12mm,体积小巧,适合空间受限的PCB布局(如小型嵌入式主板、IoT网关)。

三、典型应用场景

WRA1215S-3WR2因双路输出、宽温、高隔离等特性,广泛适配以下场景:

  • 工业控制领域:PLC可编程逻辑控制器的模拟量输入/输出模块、工业传感器(如压力/温度传感器)辅助电源、伺服驱动器控制端供电;
  • 通信设备:小型基站、光纤收发器、网络交换机的辅助控制电源,适配宽电压输入与隔离抗干扰需求;
  • 汽车电子:车载监控系统、车载通信模块(如CAN总线节点),满足宽温与高可靠性要求;
  • 医疗设备:小型诊断仪器(如监护仪辅助电源),高隔离特性符合医疗设备安全标准;
  • 嵌入式系统:小型嵌入式主板、IoT网关的电源转换模块,紧凑封装节省PCB空间。

四、可靠性与测试验证

WRA1215S-3WR2经过严格工业级可靠性测试,确保长期稳定工作:

  • 温度循环测试:-40℃~+85℃循环100次,验证宽温下输出电压、效率无衰减;
  • 隔离耐压测试:1.5kVrms/1min耐压测试,符合GB4943安全标准;
  • 短路保护测试:多次短路-恢复测试,确认保护功能响应时间<10ms,故障排除后自动恢复;
  • 纹波噪声测试:在额定负载(±100mA)下测试,纹波噪声≤100mVp-p,满足模拟电路需求。

总结

WRA1215S-3WR2作为YLPTEC推出的工业级双路隔离DC-DC模块,凭借宽电压输入、对称双路输出、高隔离、宽温工作等核心特性,成为工业控制、通信、汽车电子等领域的实用电源解决方案;紧凑的SIP封装进一步适配空间受限场景,为系统设计提供高效可靠的电源转换支持,可有效降低研发成本与系统体积。

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
