HLK-20M05 产品概述

一、产品简介

HLK-20M05 是 HI-LINK(海凌科)推出的一款高集成度开关电源模块,采用插件(通孔)封装,面向需要稳定 5V 电源输出的小型嵌入式系统与工业控制应用。模块支持宽范围输入:直流 70V350V 或交流 85VAC264VAC,单路稳压输出 5V/4A(最大输出功率 20W),适合替代传统线性电源或大功率开关电源方案而节省 PCB 设计和安装空间。

二、主要电气参数

  • 输入电压(DC):70V ~ 350V
  • 输入电压(AC):85VAC ~ 264VAC
  • 输出电压(Vout):5V
  • 输出电流(最大):4A
  • 输出功率:20W
  • 转换效率:约 82%
  • 静态功耗(空载功耗):0.1W
  • 纹波噪声:100mVp-p(典型值)
  • 隔离电压(Vrms):3000V
  • 保护功能:过流保护、短路保护

三、机械尺寸与封装

  • 尺寸(L×W×H):56mm × 32mm × 22.5mm
  • 封装形式:插件(通孔),便于焊接与更换,适合手工或波峰焊生产工艺

四、功能与特性

  • 宽输入电压,兼容全球通用交流电源以及高压直流输入,适应性强。
  • 内置过流与短路保护,提高可靠性并降低外部保护电路复杂度。
  • 3000Vrms 隔离等级,满足多数低压侧与高压侧绝缘要求,有利于系统安全设计。
  • 较高的转换效率(约 82%)与较低的静态功耗(0.1W),适合对功耗敏感的应用场景。

五、推荐应用场景

  • 嵌入式控制器、电表与仪表供电模块
  • 工业自动化控制板、传感器供电
  • 通信设备、门禁、安防摄像头(在符合功率与热管理前提下)
  • 任何需将高压直/交流电转换为稳压 5V 小功率电源的设备

六、使用与安装建议

  • 散热:模块工作时仍会产生热量,建议在有限封闭空间内保持良好通风或在有必要时加装散热措施;尽量远离热源。
  • 旁路与滤波:为降低输出纹波与提高瞬态响应,建议在输出侧并联低 ESR 电解电容(如 100µF 以上)和 0.1µF 陶瓷旁路电容。输入侧建议加保险丝与适当的 EMI 滤波器以满足系统抑制干扰要求。
  • PCB 布局:输入与输出回路应尽可能短而粗,接地良好,保留足够间距以满足 3kV 隔离要求。插件封装便于更换,但焊接质量需保证以避免接触不良。
  • 保护与可靠性:尽管模块有过流和短路保护,建议系统仍配置输入端保护(熔断器、浪涌抑制器等)以应对异常工况和浪涌。

七、选型与注意事项

  • 输出电流请勿长期超载,建议在 4A 以下连续工作并预留一定余量以延长使用寿命。
  • 高温环境或封闭不通风箱体内,应按经验适当降额使用或增加散热,以防效率下降或过热跳闸。
  • 依据具体应用,确认模块的纹波、瞬态响应与电磁兼容能否满足整机要求,必要时在系统级做额外滤波与抑制设计。

以上为 HLK-20M05 的产品概述与使用建议,供设计、选型与维护参考。若需进一步的典型电路、特性曲线或 EMC/安全认证资料,请参考厂商数据手册或联系供应商获取完整技术文档。

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
