HLK-3M05B 3W隔离电源模块产品概述

一、产品定位与核心优势

HLK-3M05B是海凌科(HI-LINK)推出的小功率AC-DC隔离电源模块,主打3W额定功率、5V稳定输出,专为需要宽电压适配、高隔离防护的低功耗电路设计。其核心优势集中在「宽电压覆盖全球市电、3kV高隔离保障安全、50mV低纹波适配敏感电路」三个维度,可直接替代传统线性电源,简化电路设计并提升可靠性。

二、电气性能参数详解

作为电源模块的核心指标,HLK-3M05B的参数兼顾适应性与可靠性:

2.1 宽范围输入特性

  • 直流输入:120V~350V DC,适配高压直流供电场景(如工业设备备用电源);
  • 交流输入:85VAC~265VAC,覆盖全球主流市电(110V北美、220V国内/欧洲),无需额外变压器,直接接入市电即可工作;
  • 电压波动适应力强:±10%输入波动下仍稳定输出,降低电网波动对后端电路的影响。

2.2 稳定输出与低功耗

  • 输出电压:5V±(典型值),匹配多数单片机、传感器的供电需求;
  • 最大输出电流:600mA,额定功率3W,可驱动小型负载(如LED显示、低功耗MCU);
  • 静态功耗:仅0.1W,待机能耗极低,适合长期通电的设备(如智能家居传感器);
  • 纹波噪声:50mVp-p(峰峰值),低噪声输出避免干扰模拟电路(如ADC采样、音频模块)的精度。

2.3 高隔离防护

  • 隔离电压:3kVrms(交流有效值),符合工业级隔离标准,有效防止高压侧故障串入低压侧,保护后端敏感电路(如医疗设备、通信模块)的安全。

三、结构与封装设计

HLK-3M05B采用插件式封装,尺寸为34.8mm(长)×20.5mm(宽)×15mm(高),体积紧凑:

  • 插件引脚设计便于手工/自动焊接,连接可靠性高,不易虚焊;
  • 外壳采用耐高温工程塑料,耐温范围-20℃~+85℃(典型值),适应多数工业/民用环境。

四、安全保护功能配置

内置双重保护机制,提升设备可靠性:

  • 过流保护(OCP):输出电流超600mA时,自动限流/切断,故障排除后自动恢复;
  • 短路保护(SCP):输出短路时立即启动保护,避免内部电路损坏,故障解除后恢复正常。

五、典型应用场景

HLK-3M05B的特性使其适用于多个领域:

  1. 智能家居:智能插座、温湿度传感器、智能门锁的辅助供电;
  2. 工业控制:PLC扩展模块、小型传感器(接近开关、光电传感器)的隔离供电;
  3. 消费电子:小型家电(加湿器、空气净化器)控制板供电;
  4. 医疗设备:低功率监护仪(血氧仪、体温计)辅助电路供电(依赖高隔离);
  5. 通信设备:小型路由器、交换机模块供电,避免高压干扰信号传输。

六、选型与使用注意事项

  1. 输入电压确认:避免接入超出120V350V DC或85VAC265VAC的电压;
  2. 负载限制:输出电流不超600mA,避免长时间过载;
  3. 散热考虑:紧凑空间内保持通风,避免模块温度过高;
  4. 隔离距离:PCB布局时,输入(高压)与输出(低压)侧需保持≥5mm距离;
  5. 焊接温度:烙铁温度≤350℃,焊接时间≤3秒,避免损坏内部元件。

HLK-3M05B以小体积、高可靠性的特点,成为低功耗隔离供电场景的优选方案,可快速集成到各类设备中,降低设计复杂度。

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
