YLPTEC(易川)QA01 电源模块产品概述

一、产品定位与典型应用

QA01是YLPTEC(易川)针对工业控制、仪器仪表、车载电子等领域设计的双路隔离电源模块,核心解决设备中正/负双电源供电的需求。其宽温适配、高隔离特性,可稳定运行于极端环境,典型应用场景包括:

  • 工业PLC输入输出模块(需-8.7V负电源驱动光耦);
  • 传感器信号调理电路(低噪声供电);
  • 车载小型仪器(-40℃~+105℃宽温要求);
  • 医疗设备辅助供电(3kV隔离抗干扰)。

二、核心技术参数详解

QA01的参数设计精准匹配工业级应用需求,关键指标如下:

1. 输入输出规格

  • 输入电压:14.5V~15.5V(适配主流15V供电系统,波动容忍度±3.3%);
  • 双路输出:
    • 正输出:15V,最大负载电流80mA(功率1.2W);
    • 负输出:-8.7V,最大负载电流40mA(功率0.348W);
  • 总功率:约1.54W(两路同时输出时的典型功率)。

2. 效率与纹波

  • 转换效率:80%(减少电源损耗,降低模块发热);
  • 开关频率:100kHz(高频拓扑设计,缩小模块体积);
  • 纹波噪声:100mVp-p(低噪声输出,避免干扰模拟电路精度)。

3. 隔离与负载能力

  • 电气隔离:3kVrms(AC,满足工业级安全标准,隔离输入输出端干扰);
  • 容性负载:最大220uF(适配后级大电容滤波,应对负载突变场景)。

4. 环境与封装

  • 工作温度:-40℃~+105℃(工业级宽温,覆盖户外、车载等极端环境);
  • 封装:SIP-5(插件式封装,体积紧凑,安装便捷,无需复杂焊接)。

5. 保护特性

  • 短路保护:输出端短路时自动切断输出,故障排除后自动恢复,避免模块/负载损坏。

三、产品优势与设计亮点

QA01的核心优势在于简化系统设计+提升可靠性,具体表现为:

1. 双路输出一体化

无需额外设计负电源电路,集成正/负两路输出,节省PCB空间与物料成本,缩短开发周期。

2. 高隔离抗干扰

3kVrms隔离电压可有效阻断输入侧电网噪声、接地环路干扰,保护敏感的模拟电路(如传感器、ADC)。

3. 宽温与可靠性

-40℃~+105℃工作温度范围,适配工业现场、车载等极端环境;短路保护功能进一步延长模块寿命,降低系统维护成本。

4. 容性负载适配

220uF最大容性负载能力,可应对开机时的电容充电冲击,避免输出电压跌落,保证系统上电稳定。

四、应用注意事项

为保证模块稳定运行,需注意以下几点:

  1. 输入电压限制:避免超出14.5V~15.5V范围,防止模块过热或损坏;
  2. 负载电流控制:正输出≤80mA,负输出≤40mA,总功率≤1.54W;
  3. 容性负载管控:输出端容性负载≤220uF,过大负载可能影响开关频率;
  4. 温度管理:避免在超温环境下长时间运行,保证散热空间。

五、总结

QA01作为YLPTEC旗下的工业级双路隔离电源模块,以双路稳定输出、高隔离、宽温工作为核心特性,精准匹配工业控制、仪器仪表等领域的供电需求。紧凑的SIP-5封装与短路保护功能,进一步提升了其在小型设备中的适配性与可靠性,是简化系统电源设计的理想选择。

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
