Power Amplifier
CHF 609.50*
Use the Power Amplifier as a power supply for DC and AC circuit investigations or to drive devices such as speakers, lamps, and small DC motors.
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.
Important Note: The Power Amplifier creates no signal on its own. It depends on a signal source, such as the LabQuest 2 or original LabQuest’s Power Amplifier App, our free Power Amplifier Frequency Generator software for PC/Mac, or Logger Pro 3.8 or newer (LabPro only)
A LabQuest Mini or LabQuest Stream does not provide a signal source. Use the Power Amplifier Function Generator software as the signal source.
What's included
Vernier Power Amplifier
(1) Power supply
(1) 3.5 mm audio cable for LabQuest control
(1) BTA cable for LabPro input and current sensing
