The 600UMPT-D full-body translational power amplifier is designed to amplify audio frequency signals and distribute them over a two-wire line, to work with loudspeaker systems with a total power up to 600 W in sound reinforcement and public address complexes. Under operating conditions the amplifier belongs to the climatic execution UHL category 4.2 GOST15150-69, is designed for operation at temperature from +5 to +40 degrees C, humidity 80% at temperature +25 degrees C, pressure from 84 to 107kPa and voltage in the power supply network 220+- 22V with frequency 50+-1Hz.
The class D power amplifier includes a high-power amplification path and has one line input. To protect the amplifier from overloading in case of forced speech signal, a limiter is included in the path.
The amplifier is provided with: short circuit protection; overcurrent protection in power supply circuits; protection against overheating of terminal transistors; protection against constant voltage at the output.
