QA01C-18 隔离电源模块产品概述

一、核心电气参数:精准匹配低压双输出需求

QA01C-18是一款双路输出隔离电源模块,核心参数针对12V系统实际工作场景优化,无需额外稳压即可直接接入:

  • 通道数:2路独立输出(18V正电压、-3V负电压),满足双电源供电需求;
  • 输入范围:13.5V~16.5V(覆盖12V铅酸电池组的浮充/充满电压区间,如汽车、工业低压电源);
  • 输出能力:18V通道最大100mA,-3V通道最大-100mA,适配小功率模拟/数字电路;
  • 转换效率:79%(小功率隔离模块中属合理水平,减少自身发热,无需额外散热);
  • 隔离电压:3.5kVrms(AC有效值,符合工业级隔离标准,抑制共模干扰);
  • 纹波噪声:60mVp-p(低噪声设计,适配传感器、模拟信号处理等敏感电路)。

二、关键性能:适配极端环境与安全需求

2.1 宽温工作:覆盖工业级温度范围

支持-40℃~+105℃的工作温度,完全匹配户外设备、车间高温/低温场景(如北方冬季户外、南方车间高温),无需额外保温/散热措施,可靠性更高。

2.2 短路保护:故障自恢复

内置短路保护电路,当输出端发生短路时,自动限制电流或切断输出;故障排除后可自恢复,避免模块损坏,提升系统稳定性(无需手动重启,减少维护成本)。

2.3 负载兼容性:支持大容性负载

最大容性负载220uF,可直接连接后端大滤波电容,进一步降低输出纹波,适配不同负载的启动需求(如电机驱动、电容性负载设备)。

2.4 电磁兼容优化

开关频率95kHz(处于音频范围外),减少电磁干扰(EMI),无需额外EMI滤波即可满足一般工业/通信设备的电磁兼容要求。

三、物理封装:紧凑尺寸适配空间受限场景

采用SIP-5直插封装,尺寸仅19.5mm(长)×9.8mm(宽)×12.5mm(高),体积小巧,适合集成到:

  • 小型PLC模块、手持仪器内部;
  • 车载电子设备(仪表、辅助控制单元);
  • 通信设备(光纤收发器、以太网交换机)的紧凑空间。

直插封装安装方便,可通过通孔焊接或插座连接,降低装配难度。

四、安全隔离:保护电路与抗干扰

3.5kVrms的AC隔离电压,满足GB/T 13028等标准要求,实现输入输出电路的电气隔离:

  • 防止高压串扰,保护后端敏感电路(如通信接口、模拟信号处理单元);
  • 抑制共模噪声,提升系统抗干扰能力(如工业现场的电磁干扰);
  • 满足工业级设备的安全防护需求,避免电路间电位差损坏器件。

五、典型应用场景

QA01C-18的参数特性使其适配多个实用场景:

  1. 工业控制:为PLC的I/O接口、传感器节点提供隔离双电源,避免现场干扰影响控制信号;
  2. 通信设备:光纤收发器、以太网交换机的辅助电路供电,实现电气隔离提升通信稳定性;
  3. 车载电子:汽车仪表、辅助控制模块的供电,适配车载12V电源波动(13.5-16.5V)与宽温环境;
  4. 小型仪器:便携式数据采集器、温湿度传感器模块,满足双输出供电需求;
  5. 医疗辅助设备:非侵入式监护仪的辅助电源,隔离电压满足一般医疗安全要求。

六、总结

QA01C-18是一款专为低压双输出隔离供电设计的高性价比模块,紧凑尺寸、宽温工作、短路保护与高隔离电压等特性,使其成为工业控制、通信、车载等场景中小功率双电源需求的可靠选择,无需复杂外围电路即可快速集成。

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
