YLPTEC B1212S-3WR2 1.5kV隔离电源模块产品概述

YLPTEC(易川)推出的B1212S-3WR2是一款专为工业级场景设计的1.5kV交流隔离DC-DC电源模块,主打小体积、宽温适应、高可靠性,核心满足12V输入转12V输出(3W功率级)的隔离供电需求,广泛适配工业控制、通信设备、汽车电子等场景。

一、核心优势:平衡性能与紧凑设计

这款模块的核心竞争力体现在“隔离安全+高效稳定+小封装适配”三个维度:

  • 1.5kVrms的高隔离电压,可有效阻断输入输出间的电气干扰,避免共地串扰影响信号精度;
  • 88%的转换效率降低自身发热,无需额外散热设计即可稳定工作;
  • SIP-4直插封装搭配超小尺寸(19.65×10.16×7mm),能轻松嵌入紧凑PCB布局,节省空间成本。

二、电气参数:精准匹配应用需求

2.1 输入输出规格

  • 输入电压范围:10.8V~13.2V,完美覆盖汽车12V系统(铅酸电池典型工作电压区间)、工业12V直流电源的波动范围,无需额外稳压;
  • 输出规格:稳定12V直流输出,最大负载电流250mA(对应3W额定功率),满足小型传感器、MCU、通信模块等低功耗器件的供电需求;
  • 转换效率:88%(典型值),相比同功率级普通模块效率提升约5%,长期运行可减少功耗浪费。

2.2 隔离与纹波特性

  • 隔离电压:1.5kVrms(250VAC/1分钟测试),达到工业级隔离标准,可隔离高压干扰、防止触电风险;
  • 纹波噪声:80mVp-p(典型值),属于低纹波电源,适合对电源纯净度敏感的模拟电路(如数据采集、传感器信号处理)。

2.3 开关与负载特性

  • 开关频率:250kHz,处于电磁干扰(EMI)易抑制的频率范围,无需复杂滤波即可满足EMC标准;
  • 最大容性负载:560uF,输出端可直接带较大电容,适应后端电路的容性负载突变(如电机启动瞬间的电容需求)。

三、机械与环境:工业级可靠性保障

3.1 封装与尺寸

  • 封装类型:SIP-4直插式,焊接工艺简单,适合批量生产;
  • 尺寸参数:长19.65mm×宽10.16mm×高7mm,体积仅约1.4cm³,是同功率隔离模块中的紧凑设计代表。

3.2 工作环境

  • 温度范围:-40℃~+85℃,覆盖工业级宽温需求(如户外控制柜、车载设备),无需降额使用;
  • 存储温度:-55℃~+125℃,提升运输与存储的可靠性。

四、保护功能:提升系统安全性

模块内置输出短路保护功能:当输出端意外短路时,模块自动进入限流保护状态,避免自身烧毁及后端电路损坏;故障排除后可自动恢复正常工作,无需手动重启。

五、典型应用场景

B1212S-3WR2的参数特性使其适配多个领域:

  1. 工业自动化:PLC输入输出模块、传感器节点、小型执行器的隔离供电;
  2. 汽车电子:车载通信模块(如CAN总线节点)、辅助传感器(如胎压监测接收器)的12V隔离供电;
  3. 通信设备:小型基站(pico基站)、无线AP的辅助电源;
  4. 仪器仪表:数据采集仪、示波器辅助通道的低纹波隔离电源。

总结来说,YLPTEC B1212S-3WR2是一款“小而精”的工业级隔离电源模块,以高隔离、高效率、宽温适应为核心,精准匹配低功率隔离供电的场景需求,是替代传统线性电源(效率低、体积大)的理想选择。

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
