WRB1205S-3WR2 电源模块产品概述

WRB1205S-3WR2是YLPTEC(易川)推出的单通道隔离降压型DC-DC电源模块,核心定位为中小功率隔离供电场景,专为需要5V稳定输出、且对电气安全有明确要求的终端设备设计,具备宽输入范围、高隔离安全、短路保护等特性,适用于工业控制、物联网终端等领域。

一、产品核心定位与应用场景

该模块聚焦低功耗设备的隔离供电需求,针对上游12V/15V常见电源系统(输入范围9V~18V),输出5V稳定电压,最大负载电流600mA,可覆盖多数终端设备的供电需求。典型应用场景包括:

  • 工业传感器节点(如温度、压力传感器的信号调理电路);
  • 物联网网关/边缘计算终端(给MCU、无线模块供电);
  • 小型医疗监测设备(需电气隔离保障安全);
  • 车载电子附件(12V车载电源转5V给小设备供电)。

二、关键电气参数解析

1. 输入输出特性

  • 输入电压范围:9V~18V(覆盖12V标准电源、15V工业电源,兼容波动±10%以内的电压变化);
  • 输出电压:5V稳定输出,最大负载电流600mA(持续输出满足3W功率需求);
  • 转换效率:78%(典型负载下减少电能损耗,降低模块发热,提升系统可靠性)。

2. 隔离与负载特性

  • 隔离电压:1.5kV(AC RMS,满足基本电气隔离要求,避免高低压电路串扰,保护后级敏感电路);
  • 最大容性负载:2200uF(后级可接大电容滤波,适应复杂负载环境,输出电压纹波更稳定)。

三、物理特性与封装设计

该模块采用SIP-7封装(单列直插式),引脚布局简洁,便于手工焊接或自动插件,适合小体积集成场景。YLPTEC的封装工艺具备抗振动、耐温性(常规工作温度范围-40℃~85℃),可满足工业级环境的可靠性要求。

四、核心性能优势

  1. 宽输入电压适应性:9V~18V的输入范围,兼容多种上游电源系统,无需额外设计电压适配电路;
  2. 高隔离安全保障:1.5kV隔离电压,有效隔离高低压回路,避免共地干扰,符合多数工业/医疗设备的安全规范;
  3. 强负载适应能力:2200uF的最大容性负载,支持后级大电容滤波,输出电压纹波控制良好;
  4. 短路保护功能:输出端发生短路时,模块自动进入保护状态,故障排除后可恢复正常工作,避免模块损坏或负载故障扩散;
  5. 能效与可靠性平衡:78%的转换效率,在3W功率等级下发热可控,结合SIP-7封装的散热设计,长期工作稳定性高。

五、应用注意事项

  1. 输入电压需控制在9V~18V范围内,避免过压损坏模块;
  2. 输出端可根据需求并联滤波电容,但需注意不超过2200uF的最大容性负载限制;
  3. 短路保护触发后,需断开负载排除故障,再重新上电恢复工作;
  4. 工作环境温度建议控制在-40℃~85℃,避免极端高温/低温影响性能。

该模块凭借稳定的电气性能、安全的隔离设计和紧凑的封装,成为中小功率隔离供电场景的实用选择,可有效降低系统设计复杂度,提升终端设备的可靠性。

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
