HF2150-1A-24DE(DIP)产品概述

一、产品简介

HF2150-1A-24DE 是宏发(HF)推出的一款插件式功率继电器,采用单刀单掷常开触点(1A, SPST-NO)结构,适用于需要高电流开关能力的控制和电源隔离场合。封装为通用DIP插件式,外形尺寸约为31.8 × 27 mm,便于插入PCB或使用插座安装。线圈额定电压为24V,线圈为无极性单线圈设计,使用灵活。

二、主要性能特点

  • 额定触点容量高:在电阻性负载下可达30A @ 240VAC,20A @ 30VDC,最大切换电流可达40A,适合大电流负载开关(如电机、灯具、加热器、继电器驱动回路等)。
  • 线圈功耗低:额定线圈功率约900mW,线圈电阻660Ω;以24V驱动时线圈电流约为24V/660Ω ≈ 36.4mA,实际消耗功率约0.87W,与标称900mW相近。
  • 响应速度快:动作时间约15ms,释放时间约10ms,适合一般控制信号响应要求。
  • 可靠接触材料:触点材料为AgCdO(氧化镉银),在耐电弧、抗焊接粘连方面性能优异(但含镉,需关注相关环保合规性与替代方案)。
  • 宽工作温度范围:-55°C ~ +85°C,适应工业级环境。

三、关键技术参数(概览)

  • 触点形式:一组常开(1A,SPST-NO)
  • 引脚数:5(DIP插件)
  • 额定线圈电压:24VDC(无极性)
  • 线圈电阻:660Ω
  • 额定线圈功率:900mW(标称)
  • 触点容量(电阻负载):30A @ 240VAC;20A @ 30VDC
  • 最大切换电压:277VAC;30VDC
  • 最大切换电流:40A
  • 接触电阻:≤50 mΩ
  • 动作/释放时间:15ms / 10ms
  • 工作温度:-55°C ~ +85°C
  • 尺寸(外形):约31.8 × 27 mm(插件封装)

四、典型应用场景

  • 工业控制:大功率继电控制回路、接触器辅助回路、加热/冷却系统控制。
  • 电源与配电:交流负载切换、UPS、配电板中中小功率负载的控制。
  • 家用电器:洗衣机、烘干机、电磁阀、照明控制等需要高电流开关的部分。
  • 交通与安防设备:车载或轨道侧非严格汽车级应用(注意环境与认证要求)的高电流开关控制。

五、安装与使用建议

  • 插件安装:建议使用与封装匹配的直插座或直接焊接到PCB,确保引脚牢固并预留散热空间。
  • 线圈驱动:由于线圈为无极性,直流驱动方向可任意;驱动电源应稳定在24V并限制电压冲击。
  • 抑制与吸收:对于感性负载或线圈旁路,建议在负载侧或线圈侧配置RC吸收、瞬态抑制器或二极管(线圈侧若并联二极管会对释放时间产生影响,DC使用时请根据需求选择)。
  • 负载类型注意:若为感性负载(电机、继电器线圈、灯具启动电流等),建议按感性负载的开关能力和寿命进行适当降额,并使用熄弧/吸收电路以延长触点寿命。
  • 环境与合规:触点材料为AgCdO,优点是抗电弧和低接触电阻;但含镉,需根据目标市场的环保法规(如RoHS限制)确认合规性或考虑替代产品。

六、选型与注意事项

  • 若需要更高的寿命(频繁切换)或更低接触电阻,可向供应商咨询触点结构或加选保护电路的方案。
  • 在高峰值起动电流场合(如感性电机启动)应按起动电流而非稳态电流选择继电器,必要时采用接触器或并联更大容量开关元件。
  • 如需板级替代或满足无镉要求,请查阅HF或其他厂家的相近型号与RoHS兼容版本。

本概述基于主要电气、机械与环境参数,供设计、选型与安装参考。具体电气寿命、机械寿命及更详细的引脚布局与安装尺寸建议参阅HF官方完整规格书与样品进行验证。

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
