TPA 4U 35 A
The solid state power broadcast amplifiers are designed in SMD technology and operate in class A mode. All power transistors are current stabilized, in order to guarantee a stable working point. Two fans take care of the cooling. For that reason the amplifier can be operated up to ambient temperatures of + 50 В°C. A temperature control switches off the complete amplifi er in case of overheating. After cooling down the amplifier will be restarted.
