A2405S-1WR3 电源模块产品概述

YLPTEC(易川)推出的A2405S-1WR3是一款双路隔离降压型直流电源模块,专为需要正负电压供电的低压电路场景设计,兼具高可靠性、紧凑体积与宽温适应性,可满足工业控制、通信设备、测试仪器等领域的供电需求。

一、核心功能与应用定位

A2405S-1WR3的核心功能是将24V(21.6~26.4V范围)直流输入转换为两路独立的±5V直流输出,总输出功率1W,每路最大输出电流100mA。其双路正负输出的设计,精准匹配了模拟信号处理电路(如运放、ADC/DAC)、传感器信号调理模块、单片机模拟前端等需要正负电源的场景,解决了单一正电源无法满足部分电路工作需求的痛点。

二、关键性能参数详解

1. 输入输出特性

  • 宽输入范围:支持21.6~26.4V直流输入,覆盖常见24V电源适配器的输出波动(通常24V电源允许±10%波动),无需额外稳压电路即可稳定工作,适配不同电网或电源设备的供电场景。
  • 双路正负输出:两路独立输出±5V,每路最大负载电流100mA,总功率1W,满足多数小型模拟电路的供电需求(如运放的正负偏置、ADC的参考电源)。
  • 强负载适应性:最大容性负载可达1200μF,可直接驱动大容量滤波电容,进一步降低输出纹波,适配对电源噪声敏感的电路(如微弱信号采集)。

2. 效率与功耗

  • 88%转换效率:在1W功率范围内实现较高效率,减少模块自身发热,无需额外散热装置即可稳定工作,降低系统功耗与散热成本。
  • 低空载功耗:空载输入电流仅1mA,待机功耗低,适合长期通电的设备(如工业传感器节点),避免不必要的能源消耗。

3. 噪声与防护

  • 30mVp-p低纹波噪声:输出纹波噪声控制在30mV以内,有效抑制电源噪声对模拟信号的干扰,提升信号采集精度(如工业压力传感器的微弱信号检测)。
  • 1.5kVrms隔离电压:输入与输出之间实现电气隔离,避免地环路干扰,同时保护后端敏感电路免受输入侧高压波动影响,符合工业级设备的隔离安全要求。
  • 短路保护功能:输出端发生短路时,模块自动启动限流保护机制,故障排除后可自行恢复,减少因短路导致的设备损坏与维护成本。

4. 环境适应性

  • 宽温工作范围:支持-40℃~+85℃的工作温度,覆盖工业现场的高低温环境(如北方户外设备、高温车间),无需额外温控措施即可稳定运行。
  • 100kHz可控开关频率:工作频率处于电磁干扰(EMI)相对易抑制的范围,配合简单滤波电路即可满足多数设备的EMC要求,降低系统电磁兼容性设计难度。

三、设计特性与可靠性

1. 紧凑SIP封装

采用SIP(单列直插)封装,尺寸仅为19.5mm×6mm×10mm,体积小巧,可直接焊接在PCB板上,节省安装空间,适合小型化设备(如便携式测试仪器、微型PLC模块)。

2. 高可靠性设计

  • 采用工业级元器件,确保宽温环境下的性能稳定;
  • 短路保护、过流保护等功能提升模块抗故障能力;
  • 隔离设计减少系统间干扰,延长后端电路使用寿命。

四、典型应用场景

A2405S-1WR3的性能特点使其适用于以下场景:

  1. 工业自动化:PLC输入输出模块、传感器信号调理电路(如压力传感器、温度传感器的运放调理);
  2. 通信设备:小型基站辅助电路、数据传输模块的正负电源供电;
  3. 测试仪器:便携式示波器、信号发生器的模拟通道电源;
  4. 单片机系统:带ADC/DAC的MCU电路(如工业数据采集卡)的正负电源;
  5. 医疗设备:小型监护仪的模拟信号处理电路(需隔离安全设计)。

总结

A2405S-1WR3作为一款双路隔离降压电源模块,以宽输入范围、双路正负输出、高隔离、低噪声、宽温工作、小体积为核心优势,精准匹配了工业级设备中对正负低压供电的需求,是替代传统线性电源(效率低、发热大)的理想选择,可有效提升系统可靠性与紧凑性。

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
