Power Amplifier
 The
new Vernier Power Amplifier allows you to drive loads with +/-10 V and
currents up to 1 A. Works with any waveform, including DC, sine, square,
triangle, and sawtooth waveforms.
The Power Amplifier can drive a variety
of loads, including speakers, lamps, small Dc motors, and RLC circuits.
- Utilizes internal feedback for accurate AC waveforms and Dc levels.
- Can provide a steady, linearly controlled DC output for driving loads
like DC motors, and precise AC
waveforms for driving things like speakers.
- Current limited to protect against overload and shorting.
- Current monitor function allows you to log real-time load current.
- Class A-B Push-Pull Amplifier provides low distortion with good
efficiency.
- Works with LabQuest, LabPro, and SensorDAQ

Power Amplifier Accessory Speaker
This kit includes a speaker and accessories used with the Vernier Power Amplifier to study mechanical waves and springs. The speaker contains a lightweight metal disc glued to the speaker cone. A drive post attached to the metal plate allows you to drive elastic materials such as strings and springs.
