Description
APA-1200 is a special audio power amplifier for electromagnetic compatibility military standard test, which is mainly used for conducting sensitivity of power line, conducting sensitivity of shell current, magnetic field radiation sensitivity test in GJB 151A-97/ 152A-97 and MIL-STD-461D/E/F, DO-160E/F, and other sensitivity tests that need to amplify audio signal.
APA-1200 audio power amplifier meets 80W (0.5 Ω) calibration power required by CS101 in gjb151a-97 / mil-std-461d and current higher than limit value of 10dB (but not more than 15A, 183db μA) required by RS101.
And meet the test requirements of CS101 30Hz-150kHz in mil-std-461E/F.
Features
1) Double independent channel design, 2 x 1250W (2Ω load) output power, each channel provides output protection function.
2) The gain (34dB) can be adjusted continuously to facilitate the test.
3) Support 2Ω output impedance matching, fully meet the low input impedance requirements of audio isolation transformer.
4) High enough power output at low impedance.
5) Provide sufficient protection function to ensure good equipment reliability.
6) The front panel is equipped with power indicator light, signal indicator light and limit indicator light to monitor the working status of the equipment at all times to prevent damage to the equipment.
7) High reliability design, suitable for all kinds of complex tested equipment.
