Protection features Protection mechanism includes antireverse connection, undervoltage, overheating, overcurrent, and short circuit protection. These safeguards help prevent damage to the device and connected equipment. Cooling and reliability Longlife ultraquiet fan with rotorlock protection. If the rotor is blocked, it does not burn, and the operation remains quiet. Widely used Suitable for a wide range of applications and configurations. Component Power amplifier chip: rt7498e Use scenarios In home theater or hifi amplifier modules to improve reliability and maintain quiet operation. In compact desktop amplifiers or portable PA systems where space efficiency and low noise are important. In embedded or small industrial control panels that require a robust power amplification stage with protective features.
