QA243-1509R3 产品概述

一、产品简介

QA243-1509R3 是 YLPTEC(易川)推出的专用 DC-DC 模块电源,属于 QAxx3-R3 系列,专为 IGBT 驱动器设计。模块采用非对称双路输出(+15V / -9V),在保证驱动电压要求的同时尽量降低 IGBT 驱动损耗。产品尺寸紧凑,封装为 SIP(19.5 × 9.8 × 12.5 mm),适合集成于变频器、伺服驱动、电焊机和 UPS 等功率电子系统中。

二、电气参数

  • 输入电压(Vin):21.6V ~ 26.4V
  • 输出通道数:2(+15V / -9V)
  • 输出功率:2.4W(总功率)
  • 输出电流(最大):100mA(每路)
  • 转换效率:典型 82%
  • 最大容性负载:2200µF
  • 隔离电压(Vrms):5kV
  • 开关频率:200kHz
  • 纹波噪声:50mVp-p

三、核心特性

  • 非对称双路输出:专为 IGBT 驱动优化,减少驱动损耗与能量回流。
  • 保护机制:具备输出短路保护与自动故障恢复功能,发生短路或异常时模块会保护自身并在故障解除后自动恢复供电,提升系统可靠性。
  • 高隔离等级:5kV RMS 隔离,满足驱动端与母线间安全电气隔离要求。
  • 高开关频率:200kHz 有利于缩小外部滤波元件体积和提高系统响应速度。

四、机械与环境参数

  • 尺寸:长 19.5 mm × 宽 9.8 mm × 高 12.5 mm(SIP 封装)
  • 工作温度范围:-40℃ ~ +105℃,适应宽温环境的工业应用。
  • 结构紧凑,便于在空间受限的功率模块或控制板上安装。

五、主要应用场景

  • 通用变频器(VFD):为 IGBT 驱动提供稳压、隔离的驱动电源。
  • 交流伺服驱动系统:满足伺服放大器对双轨驱动电压的需求。
  • 电焊机与功率电子设备:提供可靠的驱动供电并承受工业环境振动与温度变化。
  • 不间断电源(UPS):用于逆变器驱动及控制电路的隔离供电。

六、使用建议与注意事项

  • 输入侧应加适当的滤波与过压保护,避免瞬态超过 26.4V 的额定上限。
  • 输出侧根据系统情况配置去耦电容,注意总容性负载不超过 2200µF,以防影响稳定性与启动特性。
  • 在高温或靠近最大额定工作条件下建议适当降额使用,并做好散热设计,保证长期可靠性。
  • 布局时注意信号与功率走线分离,减少开关噪声耦合;必要时增加 EMI 滤波元件。
  • 利用模块的自动恢复特性可简化故障处理,但建议在系统设计中加入监测与告警逻辑以便及时排查持续异常。

QA243-1509R3 以其针对 IGBT 驱动的非对称输出、紧凑封装与工业级耐受能力,为需要隔离、稳压与短路自恢复的驱动系统提供了高性价比的解决方案。

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
