The Power Amplifier Type PA14-180 is designed to drive exciters requiring a 180 VA power amplifier. It operates with a frequency range from 40 Hz to 10 kHz at full power or from DC to 100 kHz for small signals, with minimal harmonic distortion. It can function as a voltage generator with low output impedance or as a current generator with high output impedance. The maximum RMS output-current limit is adjustable, and voltage mode is recommended for standard applications.

• General: Maximum power output is 180 VA into a 0.8 Ohm resistive load.
• Frequency Range: Full power from 40 Hz to 10 kHz; small signal from DC to 100 kHz.
• Voltage Output: Maximum 12 V RMS.
• Current Output: 5 A RMS from DC to 10 Hz; 12 A RMS from 10 Hz to 40 Hz; 15 A RMS from 40 Hz to 10 kHz; 12 A RMS from 10 kHz to 15 kHz.
• Input Voltage: Less than 5 V.
• Input Impedance: Greater than 10 kOhm.
• Power Supply: Adjustable to 100 V, 120 V, or 230 V ± 5 %, 50 Hz / 60 Hz, single phase, AC mains supply, with 580 VA power consumption.
• Monitor Output: Voltage monitor at 0.1 V/V ± 3 %, 5 Hz to 15 kHz; Current monitor at 0.1 V/A ± 3 %, 5 Hz to 15 kHz.
• Dimensions: Width 482 mm (19 in), Height 88 mm (3.5 in), Depth 450 mm (17.7 in), Weight 14 kg (31 lb).

• Frequency Range: Full power from 40 Hz to 10 kHz; small signal from DC to 100 kHz.
• Gain: Nominal 5 V/V; ± 0.5 dB from 20 Hz to 10 kHz; ± 3 dB from 10 kHz to 100 kHz.
• Total Harmonic Distortion: Less than 0.1 % from 40 Hz to 5 kHz, full power; less than 0.2 % from 5 kHz to 10 kHz, full power.
• Signal-to-Noise Ratio: Greater than 90 dB (full power, -0.5 dB).
