This board is a shell version of the PWM3TP with the same functionality but only 2 instead of 3 channels for an easy integration with Arduino projects.
It provides galvanic separation between your project and power devices such as variable frequency drives, servo motors and any other actuator with a control analog input. Each channel provides a trim-pot to adjust the output level in the range 5 to 15 V.
Two jumper selectors with three position each allow the use of any of the 6 PWM pins of the Arduino UNO. The Arduino MEGA2560 has 15 PWM pins but only 6 of them can be used in this board.
The board is fitted with standard 0.2″ screw terminals for easy wiring to external devices.
There are three versions of the board that differ only in the type of components used (see pictures):
The boards are shipped fully assembled and tested. NOTE: The headers are designed for the UNO-R3. If you want to install the shell in an older version you may need to cut short the extra pins that are not present in earlier products.
NOTE. You may power the board with only 10Vdc, but then the output can be adjusted only to 5-6V. This can be useful to connect commercial drives that provide only 10Vdc auxiliar power and have an input scaling parameter to use only 5Vfsd for the analog input.
