- 产品详情
WRV系列转换器采用了原始设计，具备高频脉冲宽度调制(PWM)电流模式调节器，能够支持极宽的输入电压范围。这种设计使得WRV系列特别适合于非稳压电源应用，例如电池和太阳能电池等，同时也适用于需要多种电源输入的系统。由于不需要预调节器，这种设计不仅简化了系统结构，还降低了成本。此外，WRV系列能够实现严格的输出电压调节，并提供非常低的无脉冲纹波，温度系数(TC)低于50 ppm/°C。
WRV系列提供三种输出电压范围：0至2kV、2.5kV或3kV。同时，它支持三种输入电压范围：3.6至10Vdc、6至15Vdc以及1.5至26Vdc，输出功率为1W。这些特性使得WRV系列转换器在多种电源环境中都能提供稳定可靠的电力转换解决方案。
