The IEC Very Low Frequency Oscillator provides a sine wave output of 0.1Hz. This means that it takes 10 seconds for the sine wave output to complete one full sine wave cycle. Output is 15V peak to peak and output current is up to 5mA.

Accuracy of frequency is about +-5%. A press button will stop the oscillation and hold the output at 7.5V. This feature allows the oscillator to synchronise with an event.

Can be used for study of phase of volts and amps in inductors and, by using LEDs, can demonstrate the operation of a rectifier bridge in slow motion.
