HLK-PM03 产品概述
一、产品简介
HLK-PM03 是 HI-LINK（海凌科）推出的小功率开关电源模块，属于 AC/DC-DC 类型、单路输出的插件式模块。模块支持广宽输入电压，能够直接从市电或直流母线获取能量，提供稳定的 3.3V 输出，适合为单片机、传感器、通信模块等低功耗电子元件供电。
二、主要参数
- 转换类型：AC/DC-DC（支持交流和高压直流输入）
- 输入电压：AC 85VAC ~ 265VAC；DC 70V ~ 350V
- 输出电压：3.3V，精度 ±0.2%
- 输出电流：最大 1A，输出功率 3W
- 静态功耗（空载功耗）：0.1W
- 转换效率：约 72%（典型）
- 纹波噪声：100mVp-p（典型）
- 保护特性：过流保护、短路保护
- 隔离电压：3kV RMS
- 封装与尺寸：插件（Through-hole），34mm × 20mm × 15mm（长×宽×高）
- 品牌：HI-LINK（海凌科）
三、保护与安全
模块内置过流及短路保护，可在异常工况下保护负载与模块自身。3kV RMS 的隔离电压保证了一次侧与二次侧之间的安全隔离，适用于需要基本安全隔离的应用。具体保护行为（如恒流、打嗝式恢复等）请以厂方详细资料为准。
四、机械与安装
HLK-PM03 为插件式封装，便于快速在试验板或量产 PCB 上安装。建议预留足够的侧面和顶面空间以利散热（模块为小功率天然通风散热，长时间满载时需良好通风）。安装前确认孔位与引脚排列，并参考官方数据手册获取准确的引脚定义及安装示意。
五、设计与应用建议
- 输入侧：在交流输入端建议配置熔断器、浪涌抑制器（MOV）或 TVS，以及电源EMI 滤波（共模电感与差模电容）以抑制干扰与浪涌。
- 输出侧：为了减小纹波与瞬态响应，推荐在模块输出端并联低 ESR 电解电容与陶瓷电容（注意电容耐压及极性）。
- 接地与屏蔽：模块一次、二次隔离，布线时保持一次侧与二次侧返回回路短且独立。若需将二次侧接地到系统地或机壳，请参考安全规范并采用 Y 电容或经过认证的连接方式。
- 散热与功率余量：尽量在常温下留有裕量运行（建议连续负载在 80% 以下或根据现场温升做适当降额），避免在高温或封闭空间长期满载运行。
- 测试：测量输出纹波时使用短接地环和合适的示波器探头接法（尽量用直探或将地线缩短），以免测量误差。
六、典型应用场景
- 工业控制与监测模块的逻辑供电
- IoT 设备、传感器节点、无线通信模块电源
- 仪器仪表、低功耗嵌入式系统供电
- 小型智能家居设备、门禁与安防模块电源
七、选型与采购建议
在使用前请参考 HI-LINK 官方数据手册核实引脚定义、典型性能曲线及环境限制（工作温度、存储温度等）。如需更高效率、更大功率或特定认证（如 UL、CE）版本，可向供应商咨询替代型号或认证信息。购买时注意渠道与出货检验，确保获得原厂或授权代理产品。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
