School Savers - Vernier PAMP Power Amplifier

Vernier PAMP Power Amplifier

The Power Amplifier takes small input signal – from a LabQuest 2, original LabQuest, or computer – and amplifies it to produce voltages from -10 to 10 V and currents up to 1 A.

Can provide a steady, linearly-controlled DC output for driving loads like DC motors or DC circuits, and precise AC waveforms for driving things like RLC circuits and speakers.
Utilizes internal feedback for accurate AC waveforms (sine, square, triangle, and sawtooth) and DC levels.
Current-limited to protect against overload and shorting.
Current monitor function allows you to log real-time load current with any Vernier interface.
Class A-B Push-Pull Amplifier provides low distortion with good efficiency.
Supports input signals from the LabQuest 2 or original LabQuest’s Power Amplifier app, the free PC software Power Amplifier Function Generator (Windows or Mac), or Logger Pro 3.8 or newer (LabPro only).
Also supports an input signal from LabVIEW via the SensorDAQ interface.

Specifications
Input connection: 3.5 mm audio cable (from LabQuest or computer) or BTA cable (from LabPro CH4)
Input Frequency range: DC to 15 kHz.
Overall gain: 10X (LabQuest/computer), 2X (LabPro)
Input impedance: 10 kO. (LabQuest/computer), 50 kO (LabPro)
Maximum input ±12 V without damage.
Pulse Width Modulation input used for producing DC offset or pure DC output

Current Sensor
Connect to Vernier interface to monitor load current
There is a 0.1 O resistor between the black terminal and ground. Current measurements are based on the voltage drop across this resistor.
