PA-5000 Amplifier Rack

PA-5000 Amplifier for WAS-5000 Wide Band Acoustic Transducer

Used to amplify an acoustic noise signal to the WAS-5000 transducer, the PA-5000 receives an input signal from a noise source and amplifies it crisply to the transducer. This signal can be from a white noise source, sine wave, or other source, depending on the user’s preference or requirements.

The PA-5000 can be configured to power either one or two WAS-5000 transducers from a single rack. When paired with a CU-5000 Cooling unit and a noise source, the PA-5000 completes the system required to operate the WAS-5000. NTS can provide design, build, and construction management for a complete acoustic facility.

General Characteristics of the PA-5000

The PA-5000 uses a digital gradient amplifier, specifically designed for use in precision voice-coil actuator control systems. It accepts a differential input signal of ±5 VDC, amplifies with a fixed gain of 40V/V, and provides a 100 Amp RMS, 200 Amp peak pulse width modulated signal (102kHz, ±7%). A PLC (Programmable Logic Controller) is used to sequence the rack operation and control system interlocks with the CU-5000 Cooling Unit. Communication with the other system components is via Ethernet IP industrial protocol. An HMI (Human Machine Interface, or Touch screen) is recommended on one of the PA-5000 racks for manual control and maintenance.
