Typical Uses
The Programmable Power Supply works well with a variety of electronic circuits,
motors, lamps, heaters, and Peltier devices, and the PASCO apparatus listed below.
Specifications
Model Number Name Comments
ET-8499 Calorimeter Set the Power Supply’s Stair function for a single heat pulse (see
page 26).
EM-8678 Charge/Discharge Circuit Use the Power Supply to charge the circuit’s capacitor or battery. Set the
Power Supply’s maximum voltage to 5 V (see page 20).
ET-8782 Thermoelectric Circuit Set the Power Supply’s maximum voltage to 10 V (see page 20).
ME-8088 Centripetal Force
Apparatus Use the Power Supply’s ramp function (see page 23) to slowly increase
the rotational speed.
ME-8750 Mechanical Oscillator
Driver Drive dynamics carts (such as ME-6950) or the Chaos/Driven Harmonic
Accessory (CI-6689A).
ME-8955 Rotational Motor Drive Drive the Rotating Platform (ME-8951) with the Magnetic Levitation
Accessory (EM-8947) or Rotational Acceleration Tank (ME-8957).
TD-8513 Heat Conduction Apparatus Power the apparatus with a positive-offset rectangle wave (see page 22)
or sine wave (the Power Supply’s default custom program, see page 28).
