VERNIER POWER AMPLIFIER
Use the Vernier Power Amplifier as a power supply for DC and AC circuit investigations or to drive devices such as speakers, lamps and small DC motors.The Power Amplifier takes small input signal – from a LabQuest 2, original LabQuest, or computer – and amplifies it to produce voltages from -10 to 10V and currents up to 1A.

• Provides 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, Vernier's free PC software Power Amplifier Function Generator (Windows or Mac) View >>>> or Logger Pro 3.8 or newer (LabPro only).
• Also supports an input signal from LabVIEW via the SensorDAQ interface.

Requirements:
This sensor requires suitable software and an interface such as one of the Vernier LabQuest variations or Vernier Go-Link.
For comprehensive details of the possible sensor/interface/software combinations see the Compatibility Guide link below.

Important Note: The Vernier Power Amplifier creates no signal on its own. It depends on a signal source, such as the LabQuest Power Amplifier App or Vernier's free Power Amplifier Frequency Generator software for PC/Mac.

A LabQuest Mini or LabQuest Stream does not provide a signal source. Use the Power Amplifier Function Generator software as the signal source.

Specifications:
Technical Details of Power Amplifier Operation
• 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 kΩ. (LabQuest/computer), 50 kΩ (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 Ω resistor between the black terminal and ground. Current measurements are based on the voltage drop across this resistor.

Included:
• Vernier Power Amplifier
• Power supply
• 3.5mm audio cable for LabQuest control
• BTA cable for LabPro input and current sensing
