Photo and product description
电参数:
输入电压范围:DC5V-35V,AC5V-22V
输出电压范围:DC1.25V-30V(连续可调)
输出电流范围:最大连续工作电流<3A(输入输出直流压差不超过10V),输入输出直流压差超过10V时请保证输出电流<2A,峰达电流可达5A
工作温度范围:0°C-100°C (为防止过温损坏,可自行加大散热或者采用其它的主动散热方式)
尺寸(长宽高):86mm X 48mm X 32mm
注:该板的稳压器LM338K为拆机件,请注意,是由于全新国产的LM338K,输出电流不会超过2A就会烧毁。
LM338K作为一种做优秀的线性稳压器,具有高稳定性、耐温高、高线性等特性,输出电压范围可达1.25V~30V连续可调,最大工作电流超过3A(最大输出电流可达5A需要加大散热器或者加大主动散热措施)。该板带有8A整流桥(带散热片),并用配备4400uF的输入滤波电容,输出2200uF的输出滤波电容,可有效的降低输出纹波与干扰。适用于30V以下供电的电器、设备、音响、数字功放等等,提供低内阻、低纹波的电源。
