A2415S-1WR3 1W双路降压电源模块产品概述

一、产品定位与核心功能

A2415S-1WR3是YLPTEC(易川) 推出的小功率降压型电源模块,针对24V直流系统设计,核心功能是将21.6~26.4V输入高效转换为±15V双极性稳定输出,满足工业、医疗等领域中低功率双极性负载的供电需求。模块内置短路保护,适配宽温环境,体积紧凑,是紧凑空间内双路供电的优选方案。

二、关键电气性能解析

1. 输入输出特性

  • 输入适配:覆盖21.6~26.4V电压范围(对应24V系统±10%波动),无需额外稳压即可直接对接工业现场的24V电源,兼容性强;
  • 双路输出:输出±15V直流电压,最大电流±34mA,总功率约1W,精准匹配运算放大器、传感器调理电路等需要双极性供电的模拟负载;
  • 负载灵活性:支持从±4mA到±34mA的电流范围,可覆盖不同功率需求的低负载场景。

2. 效率与纹波控制

  • 转换效率:达89%,在1W小功率模块中表现优异,减少自身发热,降低系统散热设计要求;
  • 低噪声输出:纹波噪声仅30mVp-p,满足高精度模拟电路(如压力/温度传感器放大、音频前置电路)对电源纹波的敏感需求,避免噪声干扰信号精度。

3. 隔离与保护设计

  • 电气隔离:1.5kVrms隔离电压,有效阻断输入输出间的干扰传递,提升系统抗电磁干扰(EMI)能力,适配对隔离要求较高的工业、医疗场景;
  • 短路保护:内置短路保护机制,输出短路时自动限流/关断,故障排除后自动恢复,保护模块及负载安全,降低现场维护成本。

三、结构与可靠性设计

1. 紧凑封装与尺寸

采用SIP(单列直插)封装,尺寸仅19.5mm(长)×6mm(宽)×10mm(高),体积小巧,便于在PCB板或设备内部紧凑布局,尤其适合空间受限的小型仪器、嵌入式系统。

2. 宽温与负载适应性

  • 宽温工作:-40℃~+85℃的工业级温度范围,覆盖户外设备、车间环境的高低温波动,无需额外温控措施;
  • 容性负载支持:最大容性负载330uF,可直接驱动较大电容负载,无需额外缓冲电路,简化系统设计流程。

3. 开关频率优化

100kHz开关频率处于常规开关电源区间,既避免过高频率带来的EMI问题,又保证输出稳定性,平衡了效率与电磁兼容性。

四、典型应用场景

A2415S-1WR3的特性使其适配多领域低功率双极性供电需求:

  • 工业控制:PLC辅助模拟电路、传感器信号调理模块(压力/温度传感器放大)、工业机器人末端执行器供电;
  • 医疗设备:低功率监护仪信号放大、小型诊断设备(如血糖仪)的模拟电路供电(1.5kV隔离满足基本医疗隔离要求);
  • 通信设备:小型基站辅助电源、通信模块的模拟信号处理电路;
  • 消费电子:高端音频设备前置放大电路(低纹波特性适配音频信号纯净度需求)。

五、选型与使用注意事项

1. 选型匹配

  • 输入电源需为21.6~26.4V直流,避免过压(>26.4V)损坏模块;
  • 负载总功率不超过1W,单路电流不超过±34mA,确保模块工作在额定范围内。

2. 布局与散热

  • SIP封装便于插装,布局时需预留适当空间(避免周围元件遮挡),虽发热小,但需保证通风良好;
  • 输入输出端建议并联10uF电解电容+0.1uF陶瓷电容,进一步滤波提升输出稳定性。

3. 故障处理

  • 短路保护触发后,需排查负载短路原因(如接线错误、负载损坏),排除后模块自动恢复;
  • 避免长期在>85℃环境下工作,防止模块性能衰减。

总结

A2415S-1WR3凭借小体积、双路输出、高隔离、宽温适配等核心优势,成为24V系统中低功率双极性供电的高性价比方案,广泛适用于工业、医疗等对可靠性要求较高的场景,可有效简化系统设计,降低成本。

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.
