QA2401C-20 隔离电源模块产品概述

QA2401C-20是**YLPTEC(易川)**推出的一款双路输出隔离电源模块,针对需要宽输入范围、双极性输出及高安全隔离的应用场景设计,兼具小型化、宽温适应性与可靠保护特性,可满足工业控制、车载电子、传感器系统等领域的电源需求。

一、关键电气参数总览

该模块核心电气参数覆盖输入、输出、效率及纹波等关键维度,适配主流24V系统应用:

  • 输入范围:支持21.6V~26.4V直流输入,兼容标准24V电源的±10%波动范围,无需额外稳压即可稳定工作;
  • 转换效率:典型转换效率达80%,有效降低模块自身发热,提升系统能效;
  • 开关频率:固定100kHz高频设计,有助于缩小模块体积,同时减少电磁干扰(EMI)影响;
  • 纹波噪声:两路输出纹波控制在低水平——-4V输出为60mVp-p,20V输出为75mVp-p,满足对电源纯净度要求较高的敏感电路(如模拟传感器、运放电路)。

二、双路输出设计特性

作为双路输出模块,QA2401C-20可同时提供两组独立输出,适配双极性电源需求:

  • 输出规格:1路负电压(-4V/100mA)、1路正电压(20V/100mA),两路最大输出电流均为100mA,满足中小功率双极性负载需求;
  • 容性负载能力:最大支持220μF容性负载,可兼容后级滤波电容,进一步降低输出纹波,适配对电源稳定性要求较高的应用;
  • 短路保护:内置短路保护功能,当输出端发生短路故障时,模块可自动限流或切断输出,避免模块损坏及负载故障扩散,提升系统可靠性。

三、安全隔离与可靠性设计

该模块针对电气安全与环境可靠性做了针对性设计,适合严苛场景:

  • 隔离电压:具备3.5kVrms(交流)隔离能力,可有效隔离输入输出端的电气干扰,防止高压串扰,保护前后级电路安全,符合工业/医疗等领域的安全规范要求;
  • 宽温工作范围:支持-40℃~+105℃的环境温度范围,可适应户外、车载、工业现场等高低温场景,无需额外温控措施;
  • 故障保护:除短路保护外,模块设计兼顾过载防护,进一步提升极端工况下的工作稳定性。

四、小型化尺寸与安装适配

QA2401C-20采用紧凑封装设计,适配空间受限的应用:

  • 物理尺寸:长19.5mm×宽9.8mm×高12.5mm,体积小巧,可直接集成到小型仪器、嵌入式系统、车载控制器等紧凑设备中;
  • 安装灵活性:无特定封装标注(按参数说明),便于通过插针或贴片方式安装,适配不同PCB布局需求,减少系统设计空间占用。

五、典型应用场景

结合核心特性,QA2401C-20适用于以下场景:

  1. 工业传感器系统:如压力传感器、温度传感器等,常需要双极性电源(正负电压)驱动,模块的双路输出可直接匹配;
  2. 车载电子设备:宽温范围(-40~+105℃)适配车载环境的温度波动,3.5kV隔离满足车载电气安全要求;
  3. 小型医疗仪器:隔离电压保障医疗设备的电气安全(防止患者触电),低纹波噪声适配精密模拟电路;
  4. 嵌入式控制系统:小型化尺寸适配嵌入式主板的紧凑空间,双路输出支持控制板上的运放、ADC等电路;
  5. 通信辅助电源:宽输入范围适配通信设备的电源波动,隔离特性减少电磁干扰对通信信号的影响。

QA2401C-20通过平衡电气性能、安全可靠性与尺寸紧凑性,为需要双路隔离电源的应用提供了一站式解决方案,可有效简化系统电源设计流程,提升设备稳定性。

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
