YLPTEC QA123C-1504R3 电源模块产品概述

一、产品定位与核心价值

YLPTEC(易川)QA123C-1504R3是一款双路隔离电源模块,专为需要正负双极性供电、高隔离防护的场景设计,核心聚焦“小体积、宽适配、高可靠”三大优势,可覆盖工业控制、车载电子、仪器仪表等多领域应用需求。其核心特性包括:双路独立输出(15V/120mA、-4V/-120mA)、5kV AC有效值隔离、-40℃~+105℃宽温工作、短路保护及SIP-5小封装,是传统线性电源的高效替代方案。

二、电气性能参数详解

1. 输入输出适配性

  • 输入电压范围:10.8V~13.2V,精准匹配12V系统(含±10%波动),适配车载12V电源、工业12V导轨电源等主流输入;
  • 双路输出特性:两路独立输出分别为15V/120mA(正输出)和**-4V/-120mA**(负输出),满足传感器、运算放大器等对双极性电源的需求,输出电流余量充足,可稳定驱动轻载负载;
  • 转换效率:典型值87%,高于同功率线性电源(通常<60%),显著降低模块自身发热,无需额外散热设计。

2. 动态与负载能力

  • 开关频率:200kHz,高于普通开关电源(通常100kHz以内),体积更紧凑,输出纹波控制更优;
  • 容性负载能力:最大支持2200μF容性负载,可直接驱动大电容负载(如滤波电容、储能电容),无需额外串联限流电阻,简化电路设计。

三、物理与环境适应性

1. 封装与尺寸

  • 封装形式:SIP-5直插封装,引脚间距符合标准插件工艺,安装便捷,适合批量生产;
  • 尺寸规格:19.5mm(长)×9.8mm(宽)×12.5mm(高),体积仅约2.4cm³,可嵌入紧凑PCB布局,节省设备内部空间。

2. 温度与环境

  • 工作温度范围:-40℃+105℃,覆盖工业级(-40℃+85℃)及部分车载高温场景(如发动机舱周边),无降额使用要求;
  • 存储温度:常规工业级存储(-55℃~+125℃),满足极端环境下的运输与存放需求(注:具体以产品 datasheet 为准)。

四、安全与保护特性

1. 隔离防护

  • 隔离电压:5kV AC有效值(1分钟测试),满足IEC 60950等安全标准,有效防止输入输出端的高低压串扰,保护后端敏感电路(如传感器、信号调理模块)。

2. 故障保护

  • 短路保护:具备输出短路保护功能,短路时自动限制输出电流,避免模块损坏;故障排除后可自动恢复正常工作,无需手动复位,提升系统可靠性。

五、典型应用场景

QA123C-1504R3的特性使其适配多场景需求:

  1. 工业控制:PLC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. 车载电子:车载显示屏背光驱动、CAN总线接口电路、车载传感器(如胎压监测)的辅助电源;
  3. 仪器仪表:小型示波器、数据采集卡、便携式测试设备的双极性供电;
  4. 通信设备:小型基站接入模块、光收发器的辅助电源;
  5. 医疗设备:低功率医疗仪器(如监护仪传感器)的隔离供电(需结合具体医疗安全标准验证)。

六、使用注意事项

  1. 输入滤波:建议在输入引脚并联10μF~100μF电解电容,抑制输入纹波,提升模块稳定性;
  2. 负载限制:避免单路输出电流超过120mA(正/负),多路负载需平均分配电流;
  3. 隔离设计:PCB布局时需保证输入输出端的爬电距离≥2mm(符合5kV隔离要求);
  4. 散热处理:因效率达87%,正常工况下无需额外散热片,若长期在+100℃以上工作,可考虑增加小型散热片辅助散热。

该模块经YLPTEC出厂校验合格,符合工业级可靠性要求,是需要双极性隔离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
