VLV step-down thyristorised chopper – Training module (ref: PED020700)
→ 30 V, 2 Amps, subvoltage thyristorised chopper module.
Parallel resistors are located in the branches in order to display the current on the oscilloscope.
One microcontroller enables the user interface & the parameters adjustments (frequency, duty cycle, operations in manual or automatic mode).
