Radio designer `` Rapri UM-1 ''.
Radio and electrical constructors, sets.Audio AmplifiersThe Rapri UM-1 (Power Amplifier) radio designer has been produced since 1991. A stereo power amplifier with a nominal output power of 2x10 W is assembled on analog A2030V microcircuits. The board contains: a heat sink with a heat sink area of 750 sq. Cm; radioelements; connectors for connecting a signal source, supply voltages and loads. The A2030V is a high-power amplifier, covered with negative feedback, protected against load short-circuits, with a supply voltage range of +6 V to ± 18 V. At maximum voltage, it is capable of delivering 4 Ohm to a load of 20 W. The microcircuits are placed on a common heatsink. The minimum EMF of the signal source is 0.7 V. Input resistance is 22 kOhm. Rated (maximum) output power at a voltage of a current source of ± 15 V - 10 (15) W. The band of reproducible sound frequencies is 20 ... 20,000 Hz. Total distortion 0.05%. The dimensions of the UM are 156x108x52 mm. The price of the UM is 30 rubles. The PA was delivered assembled, for assembly together with a preamplifier (also RK) of a full AF amplifier.
