WRB4805S-3WR2 降压型电源模块产品概述

一、产品核心定位与应用场景

WRB4805S-3WR2是YLPTEC(易川)推出的1通道隔离降压型电源模块,主打3W功率级高压输入转低压输出场景,专为需要电气隔离、宽温适应的工业/通信类应用设计。相比传统线性稳压方案,其兼顾效率与体积,可替代低频开关电源,适配紧凑空间内的高压转低压供电需求。

二、关键电气参数解析

1. 输入输出核心范围

输入电压(Vin)覆盖36V~72V宽区间,兼容工业48V总线、60V电动车辅助系统、72V储能单元等常见高压电源;输出电压(Vout)稳定5V,最大输出电流600mA,持续输出功率3W,满足多数小功率数字负载(如MCU、传感器、通信模块)的供电需求。

2. 效率与损耗控制

典型转换效率78%,高于同功率线性稳压方案(通常<60%),大幅降低高压输入时的热损耗;空载输入电流仅16mA,适合长期待机场景(如无人值守监控、低功耗传感器节点),减少待机功耗。

3. 隔离与纹波特性

具备1.5kVrms电气隔离能力,有效隔离高压侧电磁干扰,保护低压负载安全;输出纹波噪声100mVp-p,可满足一般数字电路(非高精度模拟电路)的供电要求,无需额外滤波即可稳定工作。

三、物理特性与封装设计

采用SIP(单列直插式)封装,尺寸仅22mm×9.5mm×12mm,体积紧凑,适配PCB板高密度布局;直插式引脚便于焊接固定,适合批量生产与现场维护,3W功率下自然散热即可满足全温区工作需求,无需额外散热片。

四、核心功能特性

1. 短路保护功能

内置短路保护电路,负载短路时自动切断输出,故障排除后可自恢复,避免模块损坏与负载起火风险,提升系统可靠性。

2. 大容性负载能力

最大容性负载2200uF,可稳定驱动大电容负载,应对负载突变(如电机启动、传感器上电)时的电压波动,保障输出电压稳定。

3. 高频开关设计

开关频率300kHz,高于传统低频开关电源(通常<100kHz),有助于减小电感、电容体积,进一步压缩模块尺寸,适配紧凑空间。

五、环境适应性

工作温度范围覆盖**-40℃~+85℃**,符合工业级温度标准,可适应户外低温环境(如北方冬季监控)、车间高温环境(如电机控制柜),无需额外温控措施,降低系统设计复杂度。

六、典型应用推荐

  1. 工业控制领域:PLC模块、远程IO单元的5V辅助电源(输入48V工业总线);
  2. 通信基站附属设备:基站监控摄像头、环境传感器的供电(输入48V直流电源);
  3. 电动车/储能系统:48V/60V/72V电池组的5V控制电路供电(如BMS模块、仪表);
  4. 智能家居安防:太阳能板48V输出转5V(给WiFi模块、摄像头供电,带隔离保护)。

该模块以高压兼容、隔离防护、宽温适应为核心优势,是工业、通信、电动车等领域小功率高压转低压供电的实用选择。

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
