1U高度模块化电源MU4系列,功率高达800W, BF型绝缘和极低的噪声 

TDK 公司宣布推出TDK-Lambda 品牌1U高度MU4系列AC-DC模块化电源。该产品具有极低的可听噪声，非常适用于对于噪声要求很高的测试和医疗应用。MU4系列可提供多达5路隔离的稳定输出，功率可达800W。MU4系列所有型号均满足MOPP（患者保护）绝缘，包括输出到地，以简化在 BF型医疗应用中的设计。其他目标应用有牙科、测试和测量、广播、专业音频和工业设备等。

通过智能风扇控制，MU4风扇转速降低，噪声低至36dBA*。其微控制器算法监测初级转换器和每个输出模块的温度，调整风扇速度以实现最佳冷却。

MU4系列设计为薄型1U高度，尺寸为89 x 41 x 257.5mm (W x H x D)，可实现更小的系统结构设计。

MU4系列提供9款输出模块可供选择，提供从3.3V到104V的输出电压范围，功率额定值从150W到480W。可选项有5V / 2A辅助电源，风扇故障信号，禁止和使能（用于单个或所有输出）选项，DC good，PMBus™通信和用于并联的均流功能。

使用在线快速产品查找器，可非常简单的配置和选择MU4系列产品。该查找器会自动从各种选项中生成最优化的模块选项。输入所需的输出电压和电流后，它将自动生成一个 7 位代码，以方便下单。

MU4系列的效率高达 90%，输入电压工作范围85 - 264 Vac，输入范围 180 - 264Vac时输出功率可达800W，输入范围90 - 180Vac时输出功率为600W，输入低于90Vac时降额。最大漏电流是300µA-包含所有元器件公差，接触电流小于100µA。电源可工作在环境温度-20°C - +70°C，在 50°C 以上线性降额至 50% 负载。

MU4系列输入到输出耐压4,000Vac (2 x MoPP)，输入到地耐压1,500Vac (1 x MoPP)，输出到地耐压1,500Vac (1 x MoPP)，适用于B型和BF型医疗设备。安全认证有IEC/EN 60601-1, ES 60601-1. IEC/EN/CSA/UL 62368-1, (设计符合IEC/EN 61010-1)，并带有CE / UKCA标识，符合低压、EMC和RoHS EU指令和UK法规。该系列符合 EN 55011-B、EN 55032-B 辐射和传导发射，并符合 EN 60601-1-2：2015（第 4 版）和 EN 61000-4 抗扰度标准。

*专利申请中。取决于配置，标称条件为 25°C、115Vac/240Vac 和 80% 功率。
