Found in old documentation, this circuit has only the most difficult component to obtain the PUT. The sensors are electrodes placed in the reservoir. The circuit directly controls an AC power load.
The load current can be adjusted up to about 1 A. The transistor can be TIP32 or TIP42. The...
With this step the motor is energized when the TTL or CMOS input is high. Motors up to 1 amp and...
The diodes on this power supply are 2.5 V x 1000 V. The circuit provides a very high voltage for...
